Introduction A recent interest in the activities of the Mesoamerican urbaner has revived the topic of craft specialization. Mesoamericanist’s have long suspected the household to be a fundamental unit of economic production and of sociopolitical organization (Haines et al. 2004). Moreover, investigations outside of the elite areas have provided us with information surrounding the homestead activities of families and their members. With much effort, we have now begun to comprehend the economic practices occurring within the domestic complex and the system in which these units contributed to larger exchange networks (Haines et al. 2004). Craft specialization is difficult to characterize because many variables (i.e., labor, intensity, locality) accommodate its production. As Muller (1984) has pointed out, “considerable confusion arises because archaeologists fail to distinguish between site specialization and producer specialization.” This dilemma is specific to Mesoamerica, where a number of factors surrounding craft production continue to hamper our understanding of specialization. This paper will explore the topic of craft specialization in the context of the domestic unit among the three Classic period sites of El Palmillo (A.D. 200 – 800), Matacapan (A.D. 400 – 700), and Xochicalco (A.D. 650 – 900), and the Postclassic site of Tula (A.D. 900 – 1200). It will examine the factors of production (i.e., social, economical, political, ecological) associated with craft production. Aimed at furthering our comprehension of urban economics in Mesoamerica the study will discuss workshops in the context of either site specialization or producer specialization (following Muller’s [1984] approach of further sub-dividing specialization for better characterization). As the paper will support, Mesoamerica has diverse conditions facilitating both site 1 specialization and producer specialization. Before proceeding, a general discussion on craft specialization is appropriate. Craft Specialization Introduction In craft production, perhaps the most intriguing questions center around the topic of specialization, and the interpretation of its production (Rice 1987). The nature and cause of craft specialization appears to have roots embedded in early western thinking, when the wealth of early Greek life allowed leisure time for the development of special interests (Fieser 2003). Franz Boas (1940) who was familiar with this concept explained that a surplus of food was liable to bring an increase in leisure, further sparking a desire to develop arts and crafts. In a much more contemporary setting, Adam Smith (1970) describes the factors of production in a pin factory: “Division of labor increased each worker’s skill, reduced manufacturing time, and greatly increased output.” As a result, specialization becomes efficient, increasing the output of a standard product (Smith 1970). This view of the manufacturing process (the link between specialization and standardization) will be frequently revisited throughout the length of the paper. Another perspective is that craft specialization is a component of organic (natural) and mechanical (unconscious) solidarity (Santley et al. 1989). In contemporary studies, most investigators interpret craft specialization in this manner (Clark and Parry 1990). At the archaeological level, craft specialization is tied to household activities, confined to segregated spaces, where finished products are exported outside of the initial workshop area (Santley et al. 1989). Alternatively, as Clark and Parry (1990) suggest craft 2 specialization should always involve the transfer of goods from producer local to consumer – the most useful definition in archaeological terms. According to Rice (1987) an unclear definition of specialization should be no surprise, as there further exists little consensus on how to identify the existence of specialization in commodity production. However, referencing Muller (1984), Rice (1987) does distinguish between site specialization and producer specialization. In site specialization, localities have either limited functions or intensive production activity; their activities are determined by rich environmental factors such as an abundance of water, fertile soils, minerals deposits, and so forth (Rice 1987). In producer specialization, the allocation of labor (i.e., labor force) is designated to pursuing an economic interest (Rice 1987). Producer specialization can also be described in terms of intensiveness, as part-time or full-time (Rice 1987). Further, site specialization does not infer producer specialization, and producer specialization does not infer site specialization (Rice 1987). Rice (1987) does suggests “site specialization” be coined conceptually to aspects of craft production in their own archaeological context, where as producer specialization requires further subdivision to be useful archaeologically. Domestic Units (see my literature review) Typological Classifications (see my literature review) Craft Specialization in Mesoamerica Mesoamerica An accumulation of work completed and published by Barbara Stark, Pool, and Feinman has heightened interests in the study of craft production in Mesoamerica. Because Mesoamerica facilitated the development of complex societies in various 3 regions, the investigation of its craft, in particular the context under which it was produce, can be foretelling of specialization and wider economic practices (Stark 1985). Archaeologists are aware it has been easier to study the production of pottery than the exchange of it – partly because the study requires data to coincide over long distances and identifiable periods (Stark 1985). In her early work Stark (1985) suggests that the characterization of pottery production and regionalism come about through the study of its “familial versus specialty production”; noteworthy because the contributions of seasonality, supply and demand, and family and community are examined (Stark 1985). This approach/comprehension of craft production, is perhaps the best echoed (see studies by Costin [2001]; Feinman [1999]; and Pool [2007]) (for more on Stark [1985] see my literature review). El Palmillo El Palmillo was a terraced hilltop site on the eastern edge of the Tlacolula sub valley of the greater Valley of Oaxaca. In the late 1900s, Helen Haines, Gary Feinman and Linda Nicholas (from here on after Haines et al. [2004]) carried out surface investigations that yielded evidence of artifactual waste, associated with craft production. The surface findings led to the excavation of four separate terraces – producing six domestic units (1147, 1148, 1162, 1163, 925, and 507). Full excavation of each complex identified various rooms surrounding patio structures, with evidence of multiple craft activity. Assessing the residential data at the six domesticates, Haines et al. (2004). were interested in addressing the economic organization of terrace communities (specifically, how did the inhabitants make a living?). They were further interested in the articulation 4 (their role, if any?) between the El Palmillo site and large Oaxacan exchange network, controlled by the more elite Monte Alban. The six domestic units at El Palmillo were analyzed as a single group. Chert was the most common type of material found, accounting for 92% of the stone assemblage (40,000 pieces out of 42,000 identified). Chert was a vital resource in the manufacturing of chipped stone tools (e.g., points, daggers, raspadores, drills) (Figure1). Obsidian, accounting for only 4.3% of the total assemblage was the second most type of stone material identified. The majority of obsidian in this sector was imported (there are no known of obsidian in Oaxaca) and crafted into prismatic blades, and fashioned into Sshaped/crescent eccentrics (Figure 2). Other stone tools identified at El Palmillo were basalt, granite, and rhyolite, commonly used for ground stone tools. Figure 1. Sample of raspadores from Figure 2. Obsidian eccentrics from El Palmillo: (a–c) from Terrace 507 Burial El Palmillo: (a) Terrace 1162; (b) 53; (d–e) from Terrace 507. Terrace 1163; (c, d) Terrace 507. 5 Of great significance, 75% of the 40,000 pieces of chert found at El Palmillo showed traces of expedient manufacture (Haines et al. 2004). Further explaining plentiful amounts of chert (of the expedient type) found in the stone record across the Valley of Oaxaca, and other parts of Mesoamerica (Haines et al. 2004). One tool in particular, the crudely crafted raspador was very effective in extracting fibers from maguey penqas (Hester and Heizer 1972). The use of this tool at El Palmillo, and the large amount of spindle whorls (the type associated with heavy spinning) support, if not prove that the production of maguey fiber (possibly clothing manufacture), was a common household chore (Feinman et al. 2002). In sum, domestic units at El Palmillo contributed to different stages of one or multiple forms of craft production having to do with stone or plant (Haines et al. 2004). It is noteworthy to mention that few elite items found (e.g., obsidian relics, greenstone eccentrics) were in units 507 and 925, situated farther up the hilltop closer to elite compounds. Suggesting residents of the uppermost portion were wealthier and had greater access to precious raw materials (Haines et al. 2004). The evidence demonstrates that craft production at El Palmillo was intense, yet standardized in production – carried out to support inter-community, local, and foreign exchange. Specialized craft production, such as lapidary and precious stone working was limited to wealthier patrons. It is further evident that the inhabitants of El Palmillo exploited the abundant chert deposits embedded in ignimbrite formations, and the eight species of agave in the Tlacolula Valley (Haines et al. 2004). El Palmillo as an entity specialized in chert tool production and residents took up on their own practices, evident by the eccentrics found. 6 Matacapan A paper published by Santley at el. (1989) describes the evidence for craft specialization, and the results of an ethnographic study at Matacapan, a large Classic period site in the Tuxtla region of the Gulf Coast of Mexico. The paper describes the data from two sources: (1) one-hundred stratigraphic excavations containing firing kilns, refuse dumps, fine gray pottery; and (2) collection squares containing wasters, kiln debris, and fired earth. Noteworthy is the geological composition of the Matacapan vicinity – comprised of natural riverbeds and rich mineralogical sources. Bedrock testing also identified sediment rich in kaolinite, a deposit that produces fine clay requiring minimal grinding and little sieving (Santley at el. 1989). According to Santley at el. (1989), households at Matacapan were part of a complex manufacturing system that distributed in bulk, with its product reaching both sides of the Mesoamerican coast. Supporting this claim was the large amount of Matacapan style pottery recovered from the Merchants Barrio at Teotihuacan. Most of the ceramic production occurred outside of the site’s civic center, in the occupational zones in close association with clay deposits (Santley at el. 1989). The production areas demonstrated great variability – to withstand higher temperatures all kilns excavated were tempered with volcanic ash (Santley et al. 1989). Different areas around Matacapan also manufactured different ware; four groups based on principle ware manufactured were in existence, evidence suggests (Santley et al. 1989). Figurines found within the production sample suggests its manufacturing or ritual activity was taking place prior to firing (Santley et al. 1989). Thus, ceramic production at Matacapan became organized on several levels of complexity (Santley et al. 1989). 7 Evidence from Matacapan suggests craft was manufactured in a domestic but complex environment, where different modes of production among households existed. A rich environment (i.e., rich clay sources, rivers) further intensified it. The evidence demonstrates the specialization implored in the household, where residents not only fired ceramics but also built and maintained firing kilns, prepared clay from it raw form, and further distributed their products. The activities at Matacapan uphold Longacer’s (1999) discussion that craft specialization becomes expedient in nature and standardize over time. Site specialization best describes the production at Matacapan, although the existence of producer specialization was likely interwoven. The Matacapan polity administered/distributed its product throughout Mesoamerica without intervention. Xochicalco In 1992, Ronald W. Webb and Kenneth Hirth began a series of surfaces investigations on the summit surrounding the elite site of Xochicalo. Test-pitting identified obsidian production areas, setting off a series of excavations aimed at exploring craft production and the little known activities of terrace residents. Hirth and Webb (2000) excavated three domestic units/resident workshops located on the summit of Cerro Xochicalco. The work at unit 1 (Operation H) produced numerous rooms with specific refuse dumps and areas containing evidence of obsidian craft production. Unit 1 is particularly noteworthy in that the northern patio produced several stucco-working tools and recycled storage containers containing stucco. The work at unit 2 (Operation I) produced similar evidence but under different circumstances. The distribution of waste associated with obsidian and chert tool production was restricted to only a few rooms, and several rooms 8 did not contain stockpiles of ceramic vessels and ground-stone artifacts as others proved. The work at unit 3 (Operation K) only produced sporadic evidence of lithic craft production but did identify 77 reconstructible ceramic vessels, 60% of which were the serving type (bowls of all shapes and sizes). The south patio of unit 3 also contained a stone box, possibly a community sink or storage area for serving ware (Hirth and Webb 2000). Evidence from excavated terrace units exposed multiple rooms, utilized as workshops for craft production. In all three residences, evidence suggests rooms served as both general storage areas and sleeping quarters (Hirth and Webb 2000). This simple system of production does not rule out specialization (a culmination of finely worked material was recovered); it likely suggests specialized relics were channeled outside of the standard market system. As noted for this time-period various ecological and political circumstances altered the nature and procurement of craft specialization. Evidence also suggests craft specialization was a common household responsibility in addition to farming. In my general discussion on craft specialization, Clark and Parry (1999), explore social levels in the archaeological record by distinguishing between part-time and fulltime craft specialization. With similar relevance, Hirth and Webb (2000) were able to identify rooms with specific refuse dumps, storage areas, and tools associated with craft specialization allowing them to characterize production as specialized and full-time. Appropriately craft specialization in Xochicalco was closer associated with producer specialization, than site specialization. However, rewards for terraces residents specializing in craft may have generously been under the table. Because of political 9 unrest, most of the material for production came in through exchange networks, and no natural resources in particular appear to have been exploited to a point or controlled. Tula Tula, the capital of the Toltec empire (c. A.D. 950 – 1150) is located on the northwestern flank of the Mexican basin. Archaeological data indicates that Tula grew from a modest settlement shortly after AD 700 into a larger city with an estimated population of about 60,000 (Mastache and Cobean 1989; Healan 1989). Two major archaeological research projects, one by the Instituto Nacional de Antropología e Historia (INAH) of Mexico and the other by the University of Missouri have provided a good understanding of Tula’s domestic economics. In 1980, Tulane University (a part of the Missouri Project) conducted excavations that revealed what is believed to be evidence of obsidian workshops. Surface investigations in the eastern portion of the city produced concentrations of obsidian surface debris and excavations produced over 25,000 artifacts from several residential areas (over 500,000 pieces after initial excavations). The “east flank” in other words likely represented a workshop area within the city where urbaners had both lived and worked (Healan et al. 1983). The eastflank locality contained several ridges of longitude mounds mixed with stones, typical of collapsed structures (Healan et al. 1983). To sample a full range of surface activities Healan et al. (1983) decided to expose from the top of the largest area (ridge A) (Figure 3) to its base. Ridge A was composed of structures I, II, and III (e.g., inhabitation areas, courtyards, refuse pits, hearths). In the areas surrounding the structures (the interridge) high concentrations of obsidian (in some cases 60 pieces of obsidian per liter of earth removed) were found. Healan et al. (1983) believes refuse 10 dumping was confined to the interridge and the working of obsidian took place in between structures (there was no area of encroachment between refuse dumps and domestic areas). The integrity of and the continuity of production indicates a steady organization throughout Tula’s prehispanic occupation (Healan et al. 1983). Surprisingly ridge B (not shown) just north of ridge A proved to be comparable in site specifics and production intensity, providing the same category(s) of evidence (Healan et al. 1983). Figure 3. Left – Area showing ridge A, domestic area, work area, and refuse dumps, Right – Blade product debitage (item J on Table 1) from residential units at Tula: (a) unilateral, unifacial; (b) obverse unifacial; (c) bidirectional obverse unifacial; (d) like (a) but other margin ‘backed’ by steep flaking abrasion. Image reproduced from Healan (1993). Domestic areas excavated under the Missouri Project produced over 500,000 pieces of obsidian, of which 11,990 were percussion blades, 203,647 were irregular pressure blades, 45,701 were prismatic blades, 1,204 were prismatic blade errors, and 1,155 were primary crested blades (see Table 1. for a full tabulation of obsidian artifacts from workshop complex). Aside from blades, 3,102 prismatic blade cores were 11 recovered, most of which were exhausted or in an advance stage of reduction (Healan et al. 1983). Further, 83% of the collection is green in color and comes from the Cruz del Milagro (the Pachuca source) (Healan et al. 1983). Table 1.

The high amounts of core/blade debitage (A-M in Table 1) found is representational of a core/blade industry (Healan et al. 1983). Because much of the debitage was waste, it is likely that the initial core formation was assigned to the quarry local (Healan et al. 1983). In addition to minor core preparation, all core/blade production in Tula’s workshops involved the use of pressure and not percussion (Healan 12 et al. 1983). Percussion is not used when making prismatic blades; the process is entirely accomplished by applying pressure to core cobs (Healan et al. 1983). Healan et al. (1983) have interpreted the excavated residential compounds and adjacent areas as residential entities, or barrios of extended families that were heavily engaged in obsidian working. Consumption estimates (not discussed in this paper, see Healan 1993) derived from the Missouri project conclude that most of the obsidian products from the eastflank may have been consumed by the city’s own residents within a period of about 150 years. Given the low volume of production over Tula’s reign there is little evidence suggesting state control of the local production of obsidian aside from the standard taxation (Healan 1993). Healan (1993), considers the producers of the eastern section to be a division of craft specialists who handled all details of their work, from acquiring to sponsoring programs that would distribute their product. The marketplace was the most effective way of distributing small quantities to households without paying much to the state (Healan 1993). Moreover, there is persuasive evidence of interregional trade between Central Mexico and the Gulf Coast, primarily between a pre-summed Tula based system and Isla Cerritos (Sidrys and Kimberlin 1979). It is also likely that obsidian workers set aside output for selling to the pocheta, or professional merchants, for whom evidence suggests existed at Tula (see Kristen – Graham 1989) (Healan 1993). Like many Mesoamerican sites of their time, craft production at Tula was an integral part of the local economy. Arguably, its close proximity to obsidian sources, primarily the Pachuca source allowed the Toltec state to have some say as to its administration, overseeing it “to some extant”. Because of its locality, Tula during its epoch was likely known for its obsidian utilitarian blades, further making the 13 specialization of its product economically advantageous for local craftsman. Within the domestic units of the eastflank obsidian production became standardized over time; however, there is no evidence pointing to the production process as full-time. Like most Mesoamerican sites Tula’s natural resources, complex statehood (largely unknown), and variables make it difficult to characterize production in its complete entity. My closest rendition is that both Tula elite and urbaners exploited a source that was at their disposal, adhering to both site specialization and producer specialization. Conclusion This paper attempted to identify the archaeological material from the sites of El Palmillo, Matacapan, Xochicalco and Tula, which best demonstrate the nature of craft production in a domestic context. Having found Muller’s (1984) reckoning of dividing craft specialization into two categories (producer specialization and site specialization), I felt it was practical to utilize this model to describe the production activities carried out by the Mesoamerican urbaner. Influential to my reasoning was Clark and Parry’s (1990) explanation that craft specialization be confined to certain areas of the household and outputs exported outside of the work area. I was further enlightened by the concept that craft specialization quickly becomes expedient in nature and standardize over time (see my literature review). The study had three goals: (1) examine the factors giving rise to production (i.e., social, economical, political, and ecological); (2) identify the nature of activities going on within each site (producer specialization or site specialization); and (3) Examine the continuity between standardization and specialization to explain craft specialization in Mesoamerica. 14 Based on the analysis I found that certain factors had more impact on the production of craft than others beginning with the sites ecology. The availability of natural resources (in abundance) at the sites of Matacapan (e.g., clay, water, temper), El Palmillo (chert deposits), and Tula (obsidian sources), made it advantageous for both urbaners and polities to take charge of some aspect of the trade. Politics did play a part in the procurement of craft; however, in some sites it was more occurring than in others. For example, the output of chert in El Palmillo was controlled or taxed by the more established (elite) Monte Alban, where as the output from Matacapan was the sites “bargaining power”. Separated by geography Matacapan distributed their pottery to local markets, coastal markets, and as far away as Teotihuacan. In Tula, both elite and nonelite exploited obsidian sources in a process that brought about stable social and economic conditions. Toltec polities administered the obsidian to help maintain the city; urbaner’s on the other hand produced and exported what they could for their own advantage. In Xochicalco, however, unstable political conditions confined craft production to more compacted spaces, under more control, but nonetheless the procurement of craft still existed. In terms of local economics, site polities were able to centralize (likely through ideological persuasion) the majority of craft production (if not all) to the domestic area. Moreover, it was common for the Mesoamerican urbaner to live and work in the same place: Matacapan – work areas were attached to domestic units (assembly line style); Xochicalco – work areas were confined to certain rooms of the complex; El Palmillo – work areas were the household floor; and in Tula – work areas fell in between refuse dumps and domestic units. This working and living condition allowed for all who 15 partook in the process to master (specialize) their skills. Over time craft production became expedient in nature and further standardized (Longacre 1999). The nature of the domestic workshops allowed urbaners to fulfill their state duty while encouraging the production of unique craft for their own social and economic benefits. The continuity between specialization and standardization is quite clear, such as the distinction between site specialization and producer specialization. Presenting a bigger challenge for researchers is how to conform the mixed nature of craft production (i.e., consumption, exportation) into a framework we can all agree upon, without dividing Mesoamerica.
