i.:_ A marginal range beyond the maximum limit "where exploitation is considered uneconomic, and which is generally not exploited, without modification of the system of exploitation, establishment of new settlements, or in periods of economic crisis" ( Browman, 1976, 467). In applying this model to the ethnographic data on distances to ceramic resources, several generalizations are possible. For clays (N = 85), distance ranges from less than one kilometre to 50 km (Fig. 2:1). The preferred territory of exploitation probably occurs at one kilometre because the largest percentage of the communities (29%) obtain their clay at one kilometre or less. '82% of the communities obtain thei r clay. from up to seven ki 1 ometres and this distance probably represents the upper limit of the maximum range of exploitation. Resul_ts are similar for temper, except that the sample is smaller (N = 29). Distance to temper resources ranges from less than one kilometre to 25 km with the majority of the sample (52%) obtaining their temper at· a distance of one kilometre or less (Fig 2:1). This one kilometre radius is probably the preferred territory of exploitation. 96% of the sample obtain t heir temper up to eight kilometres away suggesting that eight kilometres con­ stitutes the upper limit of the maximum range of temper exploitation. Distance·s to slip, paint and glaze resources ( Fig. 2:2) have a range of 1 - 880 km with the largest' percentage ( 32%) of the sample (N = 34) obtaining these materials up to 8 km. This radius of eight kilometres is probably the pref erred territory· o'f exploita­ tion. Additional thresholds are difficult to determine f rom the data, although 70% of the sample obtain their slips and paints from no more than 60 km away. In contrast to the distance to clay and temper resources, potters do not always travel to their slip and paint sources themselves, but rather often acquire them through trade. This fact accounts, in part, for the greater distances to slip and paint resources than clay and temper resources. This resource level of the model has two implications for the study of ceramic distribution in the past. First, because chemical and mineralogical data do not pin-point precise source locations, but identify general areas, generalizations about the range of exploitable raw materials can help determine the minimum distances at which ancient non-local ceramic distribution can be identified with confidence. Areas of production need to be separated from areas of distribution in order to identify non-local distribution using resources as a criteria. From the data, non-local distribution is neither possible nor identifiable at less than a 7-8 km.radius around a community. Potters in communities less than 14-16 km away are likely to have resource areas that overlap, and apparent non-local distribution may involve using raw materials within a resource area of another community. Thus, the identification of ceramic distribution, using resources, can best be accomplished when distances between communities exceed 16 km. Si nee all clays may not be suitable for use with local technology (e. g. Arnold, 1971) and clay resources may become exhausted or inac­ cessible, potters could exploit more distant resources and �ravel

36

in a radius of 25-50 km from their community to obt ain suitable clay and temper. Thus, communities as much as 50 (for temper) to 100 (for clay) km apart may be too close to identify ceramic distribution between them. Although t4is possibility may occur, it is not very probable since the low frequency of these distances in the ethnographic literature suggest that they occur in what Browman (1976) calls a marginal range and generally are not exploited except in times of crisis. Nevertheless, since times of increased non-local ceramic distribution co-occur with increased ceramic specialization which in turn results from demographic pressure on agricultural resources (see Arnold, 1975; 1978b; and in preparation), resource distances in the marginal range may prove to be important in defining minirrum distribution distances in the past. Finally, the analysis of slips may be more effective in showing distribution relationships than analysis of the fabric of the pottery. The ethnographic data indicate that 68% of the slip, paint and glaze resources occur outside the maximum range of clay and temper exploitation and may often be traded. Sli ps and paints are generally less complex, and physico- chemical analysis of them may prove more useful in defining non-local distributive relationships than the analysis of pastes. The second level of analysis involyes the identification of forming patterns and provides data relating to the ethnic and linguistic group of the potters. A number of ethnographers have noticed a co-occurrence of language groups and ceramic forming patterns. Reina and Hill (1978, 204-206), for example, recently. demonstrated that specific pottery forming techniques correspon­ ded to language groups in Guatemala. Cardew (1970, 10) identified four distinct variants of forming technique in Nigeria - one annng the Nupe and the others among the Yoruba. Key (1973) noted the correspondence of Austronesian speakers in New Guinea with the paddle and anvil technique and non-Austronesian speakers with the coiling method. Foster (1955) found that the vertical-half melding technique in Mexico corresponded to the Tarascan speaking area, and that the use of the movable base for making pottery corresponded to the Yucatec Maya speaking area in the northern Yucatan peninsula. Although not associated with any language group today, the ancient mold-made forming technique found on the north coast of Peru (Donnan, 1965) was associated with the Moche-Chirru civilizations which occurred from about A. D. 100 - 1476 . These civiliza­ tions probably spoke a distinct language which continued to be used up until late colonial times. This and other forming techniques on the north coast (Collier, 1959; Christensen, 1955) contrast with the use of a movable base to form pottery among Quechua speakers in the nearby Central Andes (Arnold, 1972c; Spahni, 1966; Ravines, 1963-64; 1966). These relationships are explained by the fact that forming patterns, in contrast to vessel shapes and design motifs, stem from largely unccnscious neuro-muscular patterns called motor habit patterns. These patterns are often learned as a child as consistent muscular patterns and are cultural just as attitudes and values are cultural. The association of languages and motor habits of forming pottery may be related to the learning of the potter's craft. While some of the patterns are learned by imitation,

37

others are learned by a combination of imitation and verbal In the latter case, and where the native l anguage instruction. is used extensively, certain linguistic forms may be associated with specific forming motions used to teach the craft , which differ from one language group to another. Some languages, for example, are extraordinarily rich in verb forms which convey precise meaning for kinds of motion (e. g. Hopi). With consi st ent use, these motions become unconscirns rnotor habits and di££ er from motor habits used by potters speaking other languages. Because they are unconscious motor habit pat terns are very persistent over time and are thus very difficult t o change. Foster (l948) noted that it was probably the incompat ibility of motor habit patterns that explained the difficul ty that potters had in accepting t he wheel in Mexico. Its acceptance was only possible among non-potters or where the extant motor habit patterns for making pottery were congruent with those necessary to operate the wheel. The persistence of these forming patterns over time is noted by several scholars. Charl ton (1976) found that acculturation to the wheel in the Valley of 1'!.:exico did not begin signifi cantly to replace pre-conquest forming patterns until 15-0 years after the conquest, after which change was gradual and continued up until the 20 th century. Tschopik (1950) noted the great persistence of the Aymara ceramic tradition (not just the forming patterns) in spite of Inca domination, the Spanish conquest and al most 500 years of massive acculturation. Adams (1979) noted the persistence of hand-made pottery in Nubia for over 1300 years despit e the co-o ccure nee of the wheel. Specific pottery forming techniques may al so correspond to language groups in areas where considerable ethnographic literature on pottery making exists, but where further study is necessary to discover whether the languages (or language groups) spoken by the potters co-varies with shaping methods. Schurig (1930), Solheim (1952b), MacLachlan (1938) and Tuckson and May (1975), for example, provide distribution charts of pott ery forming techniques in various parts of Oceania. Saraswati and Behura (1960) provide distribution data for forming patterns in India. Linne's (1925) classic study of South American ceramics also includes a distribution chart of forming techniques, and Foster Excellent data bases (1955) has done sirr_ilar work in Mexico. for pottery making also exist in the literature for South America (e. g. Litto, 1976), Nigeria (Thomas, 1910; Wahlman, 1972 and many others) and Oceania (e. g. Scheans, 1965; Solheim, 1952a, 1954; Solheim and Schuler, 1959; Specht, 1972). What are the implications of the correspondence of pottery forming techniques with language groups for the study of ancient ceramic distribution? This relationship would merit only trivial interest if there were no application of these associations to archaeology. One may quibble about the relationshi p of forming patterns and language groups in any given area, but the point is that shaping methods can provide a key to identifying ancient social groupsl larger than the local connrunity, whether

4 NOTES ON CERAMIC TRADE IN ANCIENT SCANDINAVIA 1 Birgitta Hulthen Summary Important production centres and ceramic distribution areas are not evident in Scandinavia prior to the iron age. It is shown that irrported pottery was frequently copied by native potters during the late iron age. There is, up to now, no evidence of ceramic mass production in Sweden until medieval times. Introduction Important production centres and s-ubstantial demand within a local area are necessary conditions for the development of ceramic trade. Imported goods can be identified in different ways. On the one hand, raw materials of imported pottery may differ from those locally available. On the other hand, decora­ tion and manufacturing techniques may, at certain times, differ from one area to another. In view of this, both ceramic raw materials and manufacturing techniques have been investigated. Studies of production centres and distribution patterns have also been of major importance in this research. Neolithic pottery The very first potters of Scandinavia belonged to the late mesolithic Erteb�lle people (from c. 5000 B. C.). Only two types of vessel were manufactured by these potters: a cooking pot with conical bottom, and an oval, shallow lamp vessel(Fig. 4:2), both products for domestic use made of local clay and tempe� (Hulthen, 1977, 23 ff). A specific distribution of these vessels may sometimes be observed. This is probably not a result of trade but due to settlement mobility (Andersen, 1975, 33). Seasonally dependent hunting and fishing caused a spread of both man and pottery. The cooking pot may also have been used for storage purposes and as a container for bringing products from fishing stations to dwelling places. The lamps have frequently been found with eel spears, and may have been used in connection with nocturnal fishing (Skaarup, 1980, 6ff; Hulthen 1981). The Erteb�lle ceramics from different areas are very homogeneous, and vessels of foreign shape and raw materials seern to be missing (Fig.4:3). Each group was provided with pottery by its own potters. 1

The frequency of each pottery type is represented as a proportion of that type by weight amongst the excavated pottery collection, dated to the period 450 B.C. - A.D. 50, from each find spot (Fig. 5: 7). The ceramic salt containers are represented as a ratio of those containers to pottery, by weight again (see also Sidrys, 1977, 99-104). This latter ratio is here called the Droitwich Salt Index (DSI). These indices represent an indirect measure of the flow rate of goods entering each site, throughout the period (see McGuire and Downum, manuscript). The best index measure­ ment would have been the weight of commodity against the weight of excavated soil, but the latter figures were rarely available. In addition, the type of site would have influenced this index since the collections from several of the sites are associated mainly with large blocks of often sterile, defensive rampart soil, and not necessarily by soils resulting from living surfaces, or activity areas. The index of each artefact type from each of the sixteen sites, which satisfy the above minimal requirements of reliability, is plotted against the distance of that site from the appropriate source (Fig. 5 : 2 , 4 , 6). The type of site (large or small hillfort, salt-working site, etc.) is also represented symbolically . With these three distributions anq the three fall-off curves based on the pottery indices and the DSI, is it possible that three different modes of exchange could account for them? What types of exchange could produce these patterns? At the lowest order of complexity, both Renfrew (1975) and Fry (1979) have described a direct type of exchange between producer and consumer, probably near the place of production, which would result in the very localized distribution of an artefact. One possible example of this model is the resultant spatial distrib­ ution of the undecorated pottery from the Clee Hills source. The patterning of this artefact is strongly affected by distance, with a maximum distribution of 35 km. There appears to be no correl­ ation between type of site and percentage of this pottery in the particular collections. Hodder (1974b and c) discusses this very corrrnon model with regard to Romano-British coarse pottery of the first to fourth centuries A. D., and suggests a strong correspondence between these distributional effects and simple competitive market principles or predicted market areas. These marketing models for coarse, unspecialized artefacts are limited by the 11constraints of tirre, energy and social cost, operating as a function of distance from the central place 11 (of production) as has been discussed many times with regard to site catchment analysis (Higgs and Vita-Finzi, 1972), Central Place Theory (C.A. Smith, 1976), and the territorial extent of early states (Cherry, 1978). The cost effectiveness of a day's journey to the Clee Hills, and back, to obtain pots had to be justified against both the quality of the artefact and any other social and material exchanges which accompanied the transaction (see Hodder, 1980). For example, the 32 km trip to the salt­ working site of Droitwich from the Clee Hills area (Fig. 5 : 7, Site 2) had its obvious material rewards. Renfrew (1977, 84) describes this restricted area of activity as "supply zone behavior", where single journeys by the consumer to the producer, or vice

region (Fig.

5 : 7, Site 1).

A very different mode of exchange is suggested by the fall-off curve for the salt containers (Fig. 5 :6). Here a rruch more distinctive pattern exists with two effects: 1) a generalized, bounded plateau in conjunction with 2) the concentration effect of a possible central locus for distribution and exchange, or as a centre for the consumption of salt (Fig. 5 :7, Site 1). This locus is not the closest site to the source area for the salt, but it does provide a clear peak in the distributional curve which suggests a focus of activity for the exchange or use of salt, at some distance from the production area (29 km). The degree and strength of that focus at Site 1 complements its relative importance to the distribution of the decorated pottery, but contrasts with the distribution of the undecorated pottery, none of which reaches the site. This superficial examination of the archaeological pattern­ ing of three different types of material culture within a small regional framewo.rk, has demonstrated several possible modes of exchange that indicate the existence of a loosely centralized system during the later iron age in western Britain. An overall similarity of material cultur·e has shown a· tendency towards considerable uniformity within this region suggesting a network along the lines of reciprocal exchange for some items at certain levels. But the complexity of the system emerges alongside this modifying effect, in the forms of supply zone activity and the presence of a centralizing factor. It has been possible, therefore, to identify different modes of exchange for different types of objects. In two out of three cases, the distribution patterns do not appear to be influenced by the type, or size, of site where the artefacts are found. The next stage of this research will improve and clarify these subjectively established differences through statistical analysis, and will review the applicability of the various modes of exchange outlined above.

of firing. Moreover, Shepard maintains that pyrometric cones are unreliable because they bloat with reducing gases and their softening point depends on rate of heating, as well as temperature. Accord­ ing to the same authority, the thermoelectric pyrometer is the most satisfactory and reliable instrument for recording ethnographic firing temperatures (Shepard 1968, 83). This.instrument comprises three main components: thermocouple, the pyrometer itself and leads connecting the two. When the thermocouple is heated, a minute electrical current is generated between the metal parts which are welded together and positioned inside a protective porcelain sheath. The amount of this current varies in direct relationship to temperature. The thermocouple is wired to the pyro�ter which consists of a sensitive galvanometer connected to the needle of a temperature dial. As Cardew points out, the thermoelectric or thermocouple pyrometer is robust, it requires no batteries because the firing itself supplies the "power" needed, and has no moving parts except the dial needle (Cardew, 1969, 308-9). Pole (1974; 1975) has employed a thermoelectric pyrometer to record ethnographic iron-smelting temperatures in Ghana. The metallic components of the type of thermocouple used by him were Platinum/Platinum 13% Rhodium, good up to 1, 400° C. After breakage of the thermocouple on two occasions as a result of con­ tact with charcoal and ore, Pole protected it whilst in use with a metal sheath, which, he was informed would melt at 1, 200° C (letter from Pole to Nicklin, 1. 3. 73). It is not surprising that laboratory or factory apparatus should get damaged or need modification under the rigours of field use. Though in my own work on pottery pyrometry it was not found necessary to protect the thermocouple in the manner described by Pole, certain other modifications, however, were essential. The chief problem in the use of the thermoelectric pyrometer for ethnographic pottery studies is that it is designed for use with a kiln (an enclosed fire like an oven), rather than an open fire of the type used in southern Nigeria for firing pots. Rudimentary kilns are found in parts of Nigeria, especially the north (Slye, 1968; Cardew, 1969; Whittle, 1980} but these do not occur in southeastern Nigeria. For the thermoelectric pyrometer to give accurate readings it ·is necessary to keep the terminal head of the therrrncouple at air temperature. In addition, if the apparatus were to be used without modification in these con­ ditions, the leads would burn and melt. Such problern, were not encountered by Pole, since the mud wall of the smelting furnace served the same function that the kiln wall would have done in the firing of pottery in a kiln. In the recording of kiln or furnace temperatures only that portion of the thermocouple which is pro­ tected by the porcelain sheath is actually exposed to the fire. It would appear that in cases where the thermoelectric pyrometer has been used in previous ethnographic pottery studies, some form of kiln was errployed by the potters.

II The pyrometric apparatus which I used in the field con­ sisted of a rectangular metal case with a needle calibrated to a 1 dial on top of the instrument which reads from zero to 1, 200° C. When in use the normal air temperature was recorded by a standard

349

glass-bulb thermometer on the side of it, and by turning a screw the reading of the instrument was adjusted to this temperature. This ensured that only the firing terr:perature itself was recorded. A base metal thermocouple was used, with Nickel-Chrome /Nickel­ Aluminium elements mounted inside an aluminous porcelain sheath. The leads inside the terminal head of the thermocouple were dis­ connected prior to fieldwork. The elements of the thermocouple were then soldered directly to a length of heat resistant (or compensating) cable. The terminal head was packed with potting clay, which provided heat and electrical insulation, and prevented undue movement of the elements while in transport or use. The leads which had been disconnected from the thermocouple were then reconnected to the compensating cable so as to facilitate easy connection of the pyrometer in the field. Before taking the pyrometer into the field the whole process of pottery manufacture in a number of specific village locations had been studied, and detailed written and photographic records compiled. w·th regard to the firing stage, an indication of the amount and type of fuel was obtained. The duration of the firing period was measured from the time that the fire was lit, until the time when the first pot was removed. The tim e at which the last pot was removed was also noted. The number of pots in the firing was counted, and also the number of breakages. The number of pots which were discarded, re cycled as grog, or patched up and sold in the usual manner was noted. (In southeast Nigeria sealing substances are employed to repair or conceal cracks.) The ·potters were consulted and the forthcoming operation discussed. They were able to inform me precisely where the hearth was to be sited before the fire was built. By this method, and by careful observation of the area where recent firings had taken place, the central point of the hearth was located on the ground, and a hole a little over twenty centimetres deep was dug (Fig. 23:1) . A narrow trench of the same depth was dug, leading from the hole. The trench ran from the centre of the hearth to about a metre beyond the edge, its length (and so that of the cable) depending upon the size of the fire. An empty tin can approxirrntely twenty centimetres in diameter was taken and a round hole some three centimetres in diameter punched at either end. The thermocouple was placed in this can so that only the porcelain sheath protruded from the hole at the top, held in place from the outside of the can by a clamp provided with the thermocouple. The can was then packed with earth, and the lid, facing downwards, closed. It was buried in the hole at the centre of the hearth so that the top of the can was level with the soil surface when sprinkled with earth. The cable leading from the bottom of the can was buried in the trench and connected to the pyrometer at a safe distance from the fire. The final procedure before the potters began to build the fire was to fill all exc?,vated areas and smooth the hearth surface so that it was as close to its undisturbed state as possible. The major object of these preparations was to ensure that the terminal head, compensating cable and pyrorr12ter were maintained at the same temperature; for the same reason the pyrometer was also protected from radiant heat from the fire.

that the systems concept is as atomistic as the older type concept. Granted, the units are larger, and what goes on within a system is viewed more in terms of relation� and processes, but even systems are customarily divided into subsystems so that their operation may be viewed as the interaction between entities. Two consequences of the atomistic nature of the approach are apropos. First, assuming that the world is made up of entities, we cannot conceive of, let alone study, phenomena as continua. Thus, transitions are out of bounds to anyone using an atomistic fram ework. Hence stem our problems in _studying the transition between system states, between hunters-and­ gatherers and agriculturalists as well as between coiling and wheel manufacturing of pottery. Faced with such a transition, we attempt to reduce its magnitude by defining system states in between, so that we have many small transitions instead of one major one. But that does not really help. Second, if there is nothing to connect the two system states, if each is an entity all by itself, we have no ground to compare the system states: we do, in fact, not know whether they are comparable at all. The same is_ true of all phenomena, and has been a major. drawback to working with datasets like the archaeological, where there are few, if any, indications on how phenomena were connected in the minds of the people studied. That is why we do not know how products compared when pre­ historic man was faced with a choice, and it is an inherent weak­ ness of _all decision-making approaches to date. Similarly, it makes us question which analytical techniques are appropriate to analysis of a certain state of a system unless these techniques have been specially developed for the one under study. A second aspect of the same problem is our view of causality: because of the atomistic nature of our optics, we do not know where the causal links lie, and what the nature of these links is. Thus, it has become all too easy to associate sequent­ iality and causality to the point where phenomena observed in a temporal sequence are thought to be causally related. In many cases, this has ohscured much more complicated relationships between variables and processes. Alternatively, we have been reduced to description of the simplest kind. For example, no cogent argument exists from this point of view concerning the change from Dressel la to Dressel lb amphorae. Besides its atomistic nature, the systemic approach has other drawbacks, such as its reductionism and its functionalism. Krupp has argued in a very lucid paper that the systems approach reduces the number of variables considered relevant in the study of a set of phenomena by the introduction of the concept of 'goal range' (1968}. His argument applies primarily to 'homeostatic' systems models, but has some valid points for 'morphogenetic' models as well. He argues that one assumes a part of the variables, conceivably connected with changes observed, as essentially stable or at least stabilizing, aiming to keep the system within its 'goal range'. As the aim of studying the system is process, the stabilizing variables tend to rermin

subsumed under the 'goal range' concept, and to remain in the background while the variables infringing on the stability· are highlighted. In the case of morphogenetic systems models, one could argue that the same is actually happening, but not through subsumption under the goal range concept. Hence, Krupp goes on, 'mechanistic' approaches considering all the variables individually have been more successful and more satisfying wherever they could be applied, i. e. in all cases with a relatively low number of variables. Systemic approaches are advocated 'faute de mieux', for cases where the variables are too numerous. As, notwithstanding their number, it is the variables which must be responsible for transitions, this is a very dangerous approach. Fortunately, however, recent research in ceramic analysis has tended to unravel variables that have thus far been included in a 'black-box'-like systems approach: raw materials analysis, analysis of shaping techniques and the reasons behind them, etc. A consequence of this particular way of reducing the number of variables is that systemic approaches tend to account for either stability or for growth, as opposed to models unraveling all variables, which may include stable and unstable equilibria. (One of the few systemic approaches which do indeed account for both is Slobodkin and Rapoport's model of human evolution, where variables preserve the system either through stability or through change, depending upon the length of the period over which they operate (Slobodkin and Rapoport, 1974; Slobodkin, 1968).)Evidently, we need to have a model accounting for both stability and change if we are to study both (seemingly?) stable states and transitions. The way in which the goal range has been defined is responsible for a couple of other drawbacks-. Drawing from biology again, where · the ultimate goal for living systems is taken to be the survival of the system, the system's survival has also been introduced as the ultimate aim of cultural systems. Two aspects have, in my opinion, been detrimental to further development of the field: f irst the idea of oal ran e itself. That is most clearly exhi ite ... Y the su stantivist- unct10na1ist discussion on the nature of pre-market economies. This dis­ cussion hinges to a great extent on the maximization-assumption of modern (rr..arket) economics. It is essentially a goal-range assumption, and has been transformed for pre-market economies in such terms as 'optimization' (cf. Jochim, 1977 for a fuller discussion). If one, however, were to analyze the variables involved, the discussion would be superfluous, and formal techniques would be seen to be easily applicable to pre-market cases. Second, the concept seems to be tied in with the marked bent for functionalism among archaeologists using systems approaches. It is a focus, derived from the same b�ological definition of goal, upon subsistence and subsistence-related activities, on the transfer of matter and energy through the system. That brings us to the other concept held responsible for some of the limitations of the present approach: 'random'. Whereas we consider a system structured, i. e. consisting of component parts with certain connections between them, ·we

consider the commodities which flow through the system, i. e. energy, matter and information as flowing randomly through components and channels between them. Kinship relations, redistributive systems, market economies are all sets of such channels: the substances, the work exchanged, and the messages passed through these channels are considered non-structuring. Evidently, commodities which have no structure, which move randomly, cannot be held responsible for whatever structure there is in a system, or for transitions between system states. For energy and matter, this seems inevitable: they both follow the law of conservation (if the amount of energy/matter grows in one place, it has to diminish in another), and can therefore never have a structuring effect. Information channels have been studied by Wright and Johnson. Their approach has essentially the same limitations as those studying energy and matter channels: no explanation for transformations, etc. (w right, 1969; 1977, etc • ; Johnson, 1973) • Later approaches by Johnson have focused on the effects of different amounts of information flowing through the channels, and the reasons why channel sets should change. Based on experimental data, Johnson has come quite far in describing (and possibly soon predicting)· such transitions. But the reasons for change are still unclear (Johnson, 1978; 1980; 1981). In sociology, others have invoked the random approach to information exchange in explaining the genesis of srrall-scale institutions (Mayhew, Gray and Mayhew, 1971; Mayhew and Levinger, 1976). But they always come up against the fact, that in a random approach, in the end, chaos is bound to ensue (second law of thermodynamics). Thus, in their case, the larger the structure, the higher the odds against its appearance or continued existence, and the quicker it must dis appear. That same law has, finally, been the basis of a very sensible attempt to monitor decay of structures (Gorman, 1973). In conclusion: the combined use of 'systems' and 'random' approaches to archaeological phenomena seems to limit fundamentally our conceptualizations to entities, stages and the like. It does not admit the study of transformations, and does not allow for the study of structuring, only of structure. Elements of a flow-structure approach If the systemic approach is too atomistic to enable us to study certain phenomena, we · have to look for a continuum-approach. If neither the systemic nor the random approach can explain structuring, we have to introduce some kind of non-random element in our rrodel. If the systemic approach does not allow for the study of both stability and morphogenesis in one model, that is a third goal which we have to set ourselves (and, in parentheses, we should include the study of decay). The argument which is to follow has been depicted in abbreviated form on Fig. 24 :1.

Stripped of everything else, including institutions, etc., we can conceive of the human world as an endless series of flows of different nature and direction. Humans flow, so do goods, energy and information. Of necessity, we must then ask two questions: (1) what moves these flows and keeps them moving? and (2) how do these flows generate institutions? Each of the questions is the starting point for a train of thought. These �et in the end. 1. What moves flows and keeps them moving? Flows occur wherever three conditiona are met: 1. The existence of a potential, for example between the point of manufacture of a commodity and a point where this comrrodity is not made. 2. · The perception of that potential, in this case by the person trading in the pots. 3. Insufficient friction to make the flow impossible: the trader must make profit. Each of these conditions has sorrE relevant consequences to be discussed. The existence of a potential. The fact that both matter and energy follow the law of conservation implies that neither can create a potential nor maintain it against the attrition caused by flows going away from it. So developed the second law of thermo­ dynamics (growth of entropy). We must conclude that the only commodity which does not follow that law, inforrrntion, is responsible for the creation and maintenance of potentials. The perception of a potential. As long as a potential is not perceived, there is no flow. Nevertheless, we cannot deny the existence of the potential. It exists, perceived or not, be­ tween the point which has more of a commodity and all points which have less. We can thus introduce the concept field (Fig. 24 :2). Perception of a potential entails a flowcrtlnform­ ation: the trader has to be informed of the fact that no pots are available in a certain place, and of the fact that the people there do indeed want pots. A flow of information does not, on the other hand, necessarily imply a flow of energy and/or matter. Cases abound, where the friction could be overcome by information flows (low energy), but not by matter or energy flows (high energy): knowing that there is a need somewhere is quite different from being able to provide the commodities to fill it. Friction. Friction is of many different kinds: physical distance, physical barriers, cultural barriers, problems in communicating. If the potential is high enough, friction will in the long run be overcome, for instance by improving technology or people learning foreign languages. It is relative to the potential and the perception thereof. 367
