Middle Bronze Age Settlement in Czelad ź Wielka – The Next Step Toward Determining the Habitation Model, Chronology, and Pottery of the Silesian-Greater Poland Tumulus Culture

: The article presents the results of research on the habitation model, chronology, and pottery production of the Silesian-Greater Poland Tumulus Culture at Czelad ź Wielka settlement (Góra county). The site of the Czelad ź Wielka is the ﬁ rst published settlement of the Tumulus culture from the area, providing the ﬁ rst evidence for developing a model of habitation change between the Early and Late Bronze Age. The typochronological analyses allowed positioning the ﬁ nds in the Middle Bronze Age, while radiocarbon dating placed the site between the late sixteenth and ﬁ fteenth century BC. Quanti ﬁ cation of technological traits were used to de ﬁ ne the general characteristics of Tumulus culture pottery in the region showing the preference for coarse, undecorated, or textile-impressed ceramics. Spatial analyses indicate the presence of a clustered settlement pattern characterized by discard of ceramic material in cultural layer. The ﬁ ndings suggest continuity of certain cultural traits from the preceding Ún ě tice and the in ﬂ uence of contemporary Trzciniec cultural circle.


Introduction
The appearance of the Tumulus culture societies in Western Poland in the Middle Bronze Age (MBA) coincides with the period of social transformations.The change toward using barrow rather than flat cemeteries (Makarowicz, 2017a), intensification of metal production (Stępniak, 1986;Staniuk, 2015Staniuk, , 2023)), and an increasingly mobile socio-economic system (Gedl, 1975(Gedl, , 1992;;Gediga, 1978) are but a few examples of processes associated with this transitional time.While the first two are well-documented in the empirical studies, the main argument for the increased mobility is the sudden decline in settlements between the Early Bronze Age (EBA) and MBA (Gedl, 1975, pp. 13-15;Gediga, 1978, p. 132;Kłosińska, 1997, p. 101;Kaczmarek, 2012a, pp. 59, 161;2012b).These findings are well-reflected in the Silesian-Greater Poland border area, where numerous funerary contexts are characterized by a fairly large number of metal artefacts, despite the absence of any forms of settlements (Cwaliński, 2012;Jaeger & Pospieszny, 2011;Makarowicz, 2017a, p. 132;Staniuk, 2023).The site in Czeladź Wielka (Góra County, Lower Silesian Voivodeship; Figure 1) is a crucial new archaeological discovery (Talarczyk-Andrałojć & Andrałojć, 2010, 2011;Talarczyk-Andrałojć, Andrałojć, & Siara, 2012) 1 , which sheds light on non-funerary characteristics of cultural change in the second half of the second millennium BC, allowing revision of the nearly 100 years old criteria of distinguishing the Silesian-Greater Poland Tumulus Culture (SGPTC) (Gedl, 1975;Gediga, 1978;Kostrzewski, 1924a,b).This will be based on the identification of habitation practices associated with the site and an attempt at establishing their dynamics in relation to other MBA sites in the region.Due to a limited number of available radiocarbon dates in the region and their absence from the immediate surroundings, the settlement of Czeladź Wielka represents the first case study for determining the absolute chronology of settlement occupation of the SGPTC in the region.
2 History of Research on MBA Occupation in the Silesian-Greater Poland Border Area The issue of MBA settlements is a consequence of three contemporary prehistoric processes, as well as the chronometric methodology in the Silesian-Greater Poland border area.The first process is the collapse of the Central European EBA civilization resulting in the disappearance of well-defined cultural traits of the Únětice culture (Kadrow, 1998(Kadrow, , 2001)).Its disappearance was associated with the emergence of the Tumulus cultural circle, in which SGPTC is a part (Gedl, 1975, pp. 77-82;Gediga, 1978;Makarowicz, 2017a).The cultural change was characterized by practicing of inhumation and cremation burial rites on same cemeteries, low frequency of ceramic finds, the lack of permanent settlements, and the invention of a new metallurgical style (Blajer, 1999;Harding, 2000;Ignaczak & Makarowicz, 1998a;Kłosińska, 1997, p. 7;Kristiansen & Larsson, 2005;Kaczmarek, 2012a, p. 157;Kneisel, 2012;Makarowicz, 2010).The clear cut-off from the preceding EBA proved challenging for conventional archaeology, where transitions between cultural groups were generally associated with gradual changes in material culture.
The second process is the increasing frequency of "eastern" traits in SGPTC, associated with the Trzciniec cultural circle (TCC) (Gardawski, 1959;Ignaczak & Makarowicz, 1998a;Kłosińska, 1997;Makarowicz, 2010).This trend was especially recognized in Central Poland on the fringe of what has been dubbed as the distribution of area of the SGPTC (Gardawski, 1959;Kłosińska, 1997).While the SGPTC was defined on the basis of funerary finds and metal artefacts, the sites associated with TCC include settlements with rich collections of ceramic finds and low frequencies of metal artefacts (Górski, 2007;Makarowicz, 2010).While the relationship between the groups is not contested, the exact nature of their relations and forms of interaction remain open for interpretation (Gedl, 1975;Gediga, 1978;Innerhofer, 2000;Kłosińska, 1997).
The main source of the discussion and the third underlying issue is the small number of settlements which have been associated with the SGPTC, as well as their ephemeral archaeological characteristics (Gedl, 1975;Gediga, 1978;Kłosińska, 1997;Kaczmarek, 2012b).The discovered sites were recognized as indicative of shortterm occupation typical of camps, rather than stable settlements (Gedl, 1975;Kłosińska, 1997;Kaczmarek, 2012a, p. 157).As such, it amplifies the discontinuity of settlement practices from the EBA or even the contemporary TCC (Czebreszuk, 2013;Górski, 2007;Jaeger, 2018;Makarowicz, 2010).Despite the long history of  1 Excavations of Czeladź Wielka were requested by KRUSZGEO Polskie Kopalnie S.A. and carried out by Refugium S.C. company to precede the exploitation of the Kowalowo I aggregate.The site was excavated between 2010 and 2012.The supervisor of the excavation was Małgorzata Talarczyk-Andrałojć, who was supported by Karolina Siara in 2012.The archaeological works covered four archaeological sites -Czeladź Wielka 12, 18, 20, and 29.Although the materials presented in this article originate mostly from Czeladź Wielka 18, we decided to overrule the site distinctions established on the basis of surface collections, and treat them as a single research area -Czeladź Wielka.research in the region (Lasak, 1996(Lasak, , 2001)), this system of short-term occupation is yet to receive a coherent definition and diachronic investigation.The existing studies focused almost exclusively on investigating funerary rites, which was supported by a fairly large number of flat and barrow cemeteries in the area (Cwaliński, 2012;Gedl, 1975;Gediga, 1978;Lasak, 1996Lasak, , 2001;;Staniuk, 2023).The result of these studies was a general model of cultural development pointing toward an increasing importance of Danubian influence which was transformed into a specific, local form of metallurgy and burial rite (Gedl, 1992;Innerhofer, 2000;Kaczmarek, 2012a).
Methodologically, the underlying challenge for a diachronic study was the incompatibility of EBA and MBA chronology of the SGPTC sites.While the EBA chronology is based on radiocarbon dates, later phenomena (excluding TCC) are based on typological sequences.New radiocarbon dates from the region using samples acquired through coring suggest a complex history of landscape changes around MBA barrow cemeteries (Stróżyk, 2019).However, they are not associated with specific material culture or other cultural traits.Other radiocarbon dates from Tumulus contexts, e.g., Czechia, Moravia, or Germany, originate from graves with finds without analogies in the SGPTC and therefore should not be used as proxies for estimating the chronology in Poland (Krištuf & Rytíř, 2009;Müller & Lohrke, 2009;Šabatová & Parma, 2020).As a result of this archaeological conundrum, the conventional dating is generally acceptedthe emergence of the Tumulus cultural circle corresponds to Reinecke's BB 1 , approximately 1600-1500 BC (Innerhofer, 2000;Kneisel, 2012;Müller & Lohrke, 2009), which overlaps with the disappearance of the Únětice culture (Czebreszuk, Müller, Jaeger, & Kneisel, 2015;Kneisel, 2012;Müller, 2012;Silska, 2012, p. 202).
Given the outlined issues, we believe that the identification and characterization of the habitation model in Czeladź Wielka allows reconsideration of the occupational traits of SGPTC, which together with radiocarbon dating, allows outlining the character of cultural change in the Silesian-Greater Poland border area between the EBA and MBA.The site of Czeladź Wielka is located ca. 3.5 km west of Wąsosz and is located on the border of four mezoregions: the Leszczyńska Heights, Żmigród Basin, Głogów Ice Marginal Valley, and Trzebnica Hills (Kondracki, 1994;Solon et al., 2018).The site was established on the upper part of a hillslope overlooking the Barycz and Orla Valley, on its northern and eastern side (Figure 2).The intersection of the two rivers was 1.5 km away from the site and there was a small spring in the immediate vicinity of the site.Majority of the site is part of the agricultural area with the western part of the site covered by a forest, which limits the possibility of determining its full extent.The geology of the site is characterized by sands with occasional patches of rocky layers (Talarczyk-Andrałojć & Andrałojć, 2011, p. 4;Talarczyk-Andrałojć et al., 2012, p. 9).
The site stratigraphy comprised of a modern humus layer, cultural layer, seven different types of soil characterized by different frequency and fraction of stone inclusions, and a subsoil (Talarczyk-Andrałojć et al., 2012, pp. 22-25).The prehistoric sequence was partially destroyed by Early Modern Period activitiesditches, digs, and tree stumps.The intensity of activities on the sites proved challenging for onsite chronological estimation of features.The majority of archaeological material (ca.57%) was documented in the cultural layer.However, during excavations, it became clear that the ceramic material forms isolated concentrations which could be linked to the underlying soil structure (Talarczyk-Andrałojć et al., 2012, p. 132).The documented features were mostly small-or medium-sized, generally with a single, brownish, or grayish fill.Fills found in the remaining features were heavily disturbed.
The majority of recovered finds were ceramic fragments; approximately 5500 pottery sherds were documented, an overwhelming majority of which were dated to the MBA (Talarczyk-Andrałojć et al., 2012, p. 132).Other finds were rare, excluding a handful number of flint or bone artefacts, no other types of material culture were discovered (Talarczyk-Andrałojć et al., 2012, pp. 132-133).Based on other reports of Bronze Age settlements in the Silesian-Greater Poland border area, no other comparable site from the second half of the second millennium BC was documented, including sites identified during field surveys (Talarczyk-Andrałojć et al., 2012).

Ceramic Analysis
The absence of available reference samples for MBA settlement ceramics was the main reason behind the decision to examine the entire available material.This process was made to determine the most prevalent traits of local pottery production.The methodology followed the system established for EBA and MBA settlement pottery in Central Hungary (Staniuk, 2020).Throughout the data collection, the system was modified to include traits specific for the finds from Czeladź Wielka.The data collection included macro-and micromorphological evaluation of shapes, decoration, and macroscopic analysis of technology.
In total, 49.06 kg of ceramic material were examined.The sample included complete forms and selected finds (1,096 units) and mass finds (4,382 units).The material was highly fragmented, the vast majority (ca.90%) of material had a surface area equal to or less than 5 cm × 5 cm.The majority of finds were indeterminate body sherds (441) and rims (357).

Macromorphology
The only set of completely preserved vessels were miniature forms, three of which typologically correspond to the beaker type from Polesie 1 (Górski, Makarowicz, & Wawrusiewicz, 2011, pp. 47-50), and one to the bowl type (Górski et al., 2011, pp. 45-47).For the perforated vessels, the only possibility of typological assignment was based on the upper vessel part, which corresponds to other similar artefacts found in TCC contexts (Górski et al., 2011;Grygiel, 2012;Makarowicz, 2010Makarowicz, , 2016)).The discovered forms were of slightly different shape: CZE_SF_487 had a semi-spherical shape and was accompanied by a standing foot; CZE_SF_491 had a conical shape; CZE_SF_488 was conical with a profiled base.The miniature bowl (CZE_SF_505) with irregular wall shape can only generally be associated with monopartite, unprofiled bowls (Figure 3).In general, miniature forms in the SGPTC are considered "foreign" or at least rare objects (Gedl, 1992, p. 17); the single reported example is the artefact discovered in a grave in Krzelówa direct analogy for the CZE_SF_487 form (Gedl, 1975, p. 113, Tab. 2:4).The remaining vessels lack direct analogies, although miniature vessels are well-documented in TCC, Lusatian, or, in general, Bronze Age archaeology of Central Europe (Górski et al., 2011;Kłosińska, 2008;Oleszczak & Twardowski, 2011;Wójcik, 2020).

Micromorphology
Due to the small number of preserved vessels, typological evaluation was based on the examination of micromorphological traits.These were almost exclusively limited to lip shapes (Figure 4).
In total, 32 types were distinguished with types LP003, LP002, LP041, LP010, LP004, LP006, and LP020 representing the most common solutions.Types LP003 and LP002 are common for Central European Bronze Age, which suggest that pottery production between EBA and MBA remains stable in terms of some micromorphological traits.

Technological Analysis
Macroscopic analysis of technology was based on fresh breaks or cleaned existing breaks.The main objective of the analysis was to determine the degree of technological homogeneity of the assemblage.
Clay preparation was fairly consistent; crushed rock temper was the dominant non-plastic inclusion (ca.98%), in some instances combined with sand, mica, or crushed rocks of a higher fraction (gravel).The second most frequent non-plastic inclusion was sand (ca.2%).Single sherds tempered with grog or without visible inclusions were documented.During data collection, it became apparent that the crushed rock inclusion was usually white.Although the exact frequency was not counted, we estimate that at least 70% of the pottery with crushed rock inclusions comprised of white crushed rocks.This observation is in accordance with the technological markers for Late Únětice, Tumulus, or TCC assemblages in the Polish Lowlands (Diers, 2010;Ignaczak & Makarowicz, 1998a,b;Silska, 2012).The majority of the assemblage was characterized by moderate distribution of non-plastic inclusions in the clay matrix (ca.73%), followed by poorly distributed inclusions (ca.15%).Size-wise, the group of inclusions between 1 and 3 mm was preferred (ca.75%), followed by large inclusion measuring above 3 mm (ca.13%).Overall, it was not observed that the amount of temper resulted in the cracking of external vessel surface (ca.86%).
Based on the combination of technological traits (type, size, and visibility of inclusions on the vessel surface), 27 technological groups were identified.Group 15 (61%) was the most frequent (Figure 5a).
The high degree of fragmentation severely impacted the possibility of determining wall construction techniques.As such we decided to focus exclusively on analyzing the wall thickness distribution (Figure 5b).The majority of finds fell between the 6 and 9 mm (88%) range, which points toward preference of thick-walled vessels.The presence of wall-thickness exceeding 9 mm suggests the limited presence of large storage forms used for storage.Although the detailed documentation of techniques was problematic, it is suggested that coiling supplemented by pinching vessel bases was used.Both techniques are core building methods in Central European Bronze Age (Kreiter, Sofaer, & Budden, 2006;Mogielnicka-Urban, 1984;Michelaki, 2006;Staniuk, 2020).
Interior surface treatment was more constrained with only seven types documented (Figure 5d).Smoothing and burnishing were also frequent, one instance of roughening was recognized (eventually very strong scrubbing), as well as surfaces without any special treatment.
Examination of cross-section coloring suggests that the majority of finds were fired in reducing atmosphere (Figure 5e).In the majority of cases, the cross-section was not uniformly colored, which suggests that maintenance of stable firing conditions was impossible.This led to the surfaces varying in color from the core.

Decoration
Each element unassociated with the technological steps presented above was treated as part of decoration to avoid unclear criteria of treating certain elements as more functional than others, e.g., lugs or ribs (Staniuk, 2020, p. 194).In total, 370 decorated fragments were distinguished (ca.7%).The low frequency of decorated ceramics is common among MBA settlements in the Polish Lowlands (Górski et al., 2011;Makarowicz, 2013Makarowicz, , 2016)).The vast majority of decoration was placed on the body (ca.95%).
The most frequent decorative technique was impressing, followed by incising, and applying different elements (Figure 6a).The remaining techniques suggest local familiarity with other decorative techniques but at the same time highlight reluctance toward their adaptation.Unexpectedly a single example of painted decoration was documented, achieved with a black substance reminiscent of birch tar (cf. Figure 9).
 2 A detailed analysis of textile pottery will be presented elsewhere (Skrzyniecka et al. in preparation).
Considering the thickness of sherds with perforated surfaces discovered in Czeladź Wielka (5, 6, 7, 8, and 9 mm), both forms could have been used on site.
In Czeladź Wielka, the preferred way to implement decoration was to cover the entire surface of the vessel (Figure 6c).Ornament combination was very rare, which at least partially can be explained by the high fragmentation of the ceramic material.Irrespective of preservation, the decoration analysis confirms that if decorative traits are to be considered as cultural markers, the analyzed inventory should be associated with the SGPTC due to the prevalence of textile decorations.However, the large frequency of ribs points toward influence from the TCC.

Spatial Analysis
Spatial analysis of find distribution was linked to two types of archaeological features: refuse pits and cultural layer.Initially the distribution of features was used to infer the presence of linear structures associated with functional divisions within the settlement, proving the existence of stable architecture.Analysis of feature distribution ruled out the presence of fixed architecture (no spatial correlation, one identified structure measuring more than 100 m 2 is indicative of later Early Modern Period architecture).We determined that later activities on the area of the archaeological site resulted in the formation of secondary features with re-distributed MBA finds.This is further supplemented by the low frequency of ceramic materials found in features, which contrasts with the distribution of material in the cultural layer, as well as radiocarbon dating (Figure 8).
The distribution of finds in the cultural layer highlights the presence of "empty spaces" within the site, as well as the existence of intense deposition zones.This points toward a clustered settlement model, where the group used intensively one part of the occupied area leading to an increased deposition of ceramic material.After a while (maybe a season), the group would move across the occupied area, allowing post-depositional factors to start affecting the distribution of finds in a radial fashion.This occupational model was documented on other MBA sites, e.g., Szczepidło or Polesie 1 (Górski et al., 2011;Makarowicz, 2016).The commonality of this settlement model could suggest an existence of stronger ties between the SGPTC and TCC.

Absolute Chronology
We acquired four radiocarbon samples from the site (Table 1).Radiocarbon dating took place in the Poznan Radiocarbon Laboratory.Three samples were acquired from archaeological features -214, 316, 460.The fourth sample was obtained from a vessel found in the cultural layer of sector HaII/82 D. The dated bone samples suggest that the animal bones were deposited in the Early Modern Period, despite the selection of features with MBA ceramics.As such the post-depositional transformations of the prehistoric occupation was substantial.
The dated ceramic vessel proved more successful, the wood tar found on the ceramic vessel (sample Poz-143258) had an estimated date of 3215 ± 35 BP, which after calibration in OxCal v. 4.4 (Bronk Ramsey, 2009;Reimer et al., 2020) was dated to 1506-1445 (68.2%) and 1536-1416 (95.4%) cal BC (Figure 9).This indicates that the site can be safely placed in the second half of the second millennium BC, between the late sixteenth and fifteenth century BCE.
The radiocarbon date from Czeladź Wielka is the first absolute date from the Silesian-Greater Poland border area, especially from a settlement context.Based on a comparative analysis with other dated sites in Western and Central Poland, the site of Czeladź Wielka was used after the decline of the fortified settlement in Bruszczewo, simultaneously with the creation of a new, long-term occupation in Szczepidło or Polesie 1 (Figure 10).The site was contemporary with the barrow in the Krotoszyn Forest or short-term occupation of Cichmiana 2 or Krągola, as well as the cemetery in Górzyca.Given the disintegration of the Únětice culture, the dating of the materials from Czeladź Wielka suggests a very short-term period of cultural change between the EBA and MBA, which rather quickly resulted in an emergence of a new habitation model.Its overlap with the TCC could point toward a direction of origins or at least drawing of inspirations from a different cultural milieu.

Discussion
We begin the identification of habitational practices in Czeladź Wielka by examining the settlement model.Currently, a systemic approach for distinguishing settlement types in Bronze Age archaeology is relatively   open (Brück & Fokkens, 2013;Harding, 2000;Sørensen, 2010), with locally documented domestic architecture suggesting that occupational models in the Polish Lowlands were relatively diverse (Makarowicz, 2010).Based on the size of the occupied area and the characteristics of the archaeological record, we consider the settlement as representative of a seasonal model similar to a short-term camp.The low number of features associated with permanent architecture, limited to 30 postholes and a single semi-sunken floor house, points toward the use of temporary dwellings.The large number of pits, assuming that several of them can be dated to the MBA, suggest a refuse management strategy employed to reduce the excessive number of discards on the occupied surface.Last but not least, the linearly-arranged "empty spaces" suggest the presence of occupational zones within the camp.
We treat the accumulation of archaeological finds in the cultural layer as an additional argument in favor of the seasonal occupation model.A similar situation was encountered in Lgów, Szczepidło, or Polesie 1 (Grygiel, 1977, p. 64;Górski et al., 2011;Makarowicz, 2016).In all cases, ceramics were the dominant find type.The overall homogeneity of the ceramic material suggests short-term occupation without a long-term occupational practice, a pattern especially common for other MBA sites in the Polish Lowlands (Makarowicz, 2010, p. 96).
The chronological positioning of the site further supports the short-term occupational model of Czeladź Wielka.The relative dating of described finds especially the textile-impressed pottery, as well as the absolute dating positions in firmly in the half of the second millennium BC, specifically the fifteenth century BC.Overall, this time period represents a transitional time when the societies living in the post-Únětice world are yet to adapt the cremation burial rite associated with the Urnfield culture (Kadrow, 1998;Kristiansen & Larsson, 2005;Nørgaard, Pernicka, & Vandkilde, 2021).This corresponds to phase BB 1 and the increasing influence from the Carpathian Basin (Kaczmarek, 2012a, p. 157), as well as the rise of barrow cemeteries in the Silesian-Great Poland border area, e.g., Smoszew (Stróżyk, 2019), as well as across Central Europe (Chvojka et al., 2011;Krištuf & Rytíř, 2009).
While the occupational model can be considered short-term, we consider certain line of evidence as maintained by a complex social group.The stylistic diversification of material culture within a relatively small collection of artefacts can only partially be explained by functional choices (use of ceramics for food preparation and storage).It most likely points to a pottery network linked to specific potters or workshops.If stylistic differentiation such as the number of different lip types can be treated as evidence of different pottery workshops, the people living in Czeladź Wielka had access to wares produced by more than a dozen individuals.
From a technological standpoint, these workshops were most likely drawing from a shared technological skillset, all based on the standardized choice of non-plastic inclusionscrushed rocks.This preference represents a continuity of practices established in the preceding Únětice period (Dibbern, 2010;Diers, 2010;Silska, 2012).Persistence of this practice should be considered as one of the threads for maintaining knowledge despite the large-scale social changes between the EBA and MBA in the region.Wall thickness of the vessels points toward a certain degree of specialization, since the majority of finds are thick-walled vessels used for transport, storage, and processing of pottery.These functional properties are often accompanied by larger volumes of vessels, which require acquisition of motor skills which come with experience.Furthermore, the differentiation of surface treatments based on the size of the vessels is a further argument toward a functionalist perspective on pottery productiona wider skillset was used to finish the exterior of the vessel than the interior.Consistency of visual preferences was also documented since the majority of vessels were characterized by a reducing firing atmosphere, although it was not successfully maintained.As such, the pottery of Czeladź Wielka fits well into the Central European Bronze Age ceramics, where the rise of metallurgy was not immediately tied to the improvement of pottery firing techniques (Kreiter, 2007;Michelaki, 2006;Staniuk, 2020).
The absence of fine ware ceramics raises questions regarding the consumption practices, which were perhaps overtaken by nonceramic vessels.Alternatively, this could be treated as a change toward collective food consumption where a single pot was used to eat from by a group of people.
In the Polish Lowlands, the high frequency of textile impressed pottery was reported for the EBA settlement of Bruszczewo (Schaefer-Di Maida & Kneisel, 2019) and the Middle-Late Bronze Age settlement in Szczepidło (Makarowicz, 2016).However, the frequency of textile impressions in Czeladź Wielka is relatively higher than that in both these sites (ca.3% of the entire material; Bruszczewoca.2%; Szczepidłoca.0.5%).Other SGPTC sites had a much lesser proportion of textile-impressed ceramics (Gedl, 1975, pp. 62-64).
However, the overall low frequency of pottery decoration in Czeladź Wielka is also a trait associated with MBA pottery.The variety of documented elements, such as impressions, applications, or incisions were additional production steps which were generally avoided in pottery production.Currently, no explanatory model for the low frequency of decoration was provided for the MBA, primarily due to the scarcity of available ceramic inventories.However, the studies of decorative motifs on metal artefacts (Gedl, 1992) suggest that aesthetic principles and regional preferences were well-established in the MBA.The existence of parallel stylistic networks suggests a complex exchange model encompassing different items, each subject to selection based on different principles.This points to a complex social model, requiring independent investigation of possible links between craftsmanship, social status, and distribution networks for the different artefacts.Given the existing data on ceramic finds from Czeladź Wielka, we emphasize the overall visual similarity of finds to the TCC assemblages (Kłosińska, 1997;Makarowicz, 2010).While the problem of syncretism between the SGPTC and TCC is not new, our results highlight the importance of comparative analysis of stylistics and technology between these two groups (Gardawski, 1959;Gedl, 1975;Gediga, 1978;Ignaczak & Makarowicz, 1998b).
Overall, the emerging image of the social model of the SGPTC is a complex one: on the one hand, based on short-term habitation, it potentially emerges as a result of the political vacuum created by the disintegration of the Únětice culture, on the other, it represents a well-maintained and integrated system of skill transmission.As such, we suggest that we are dealing with specialized, well-integrated, small groups of people, who were able to organize short-term occupation and traverse the landscape.Although Czeladź Wielka fits in with existing hypotheses of the occupational models in SGPTC (Kłosińska, 1997;Kaczmarek, 2012a;Makarowicz, 2017a;Vandkilde, 2007), our findings on the material culture point toward the complexity of social organization during the mid-second millennium BC.

Conclusion
Based on stratigraphic and material culture studies, we suggest that the SGPTC site in Czeladź Wielka represents a model of short-term seasonal occupation in the MBA.The radiocarbon dating corresponds to the decline in the EBA settlement in Bruszczewo and the spread of short-term occupation from the Silesian-Greater Poland border area toward north-east in the fifteenth century BC.
The short-term occupation model was probably accompanied by a well-established system of pottery production, most likely explained by a complex social model maintained by small groups of people.The high frequency of textile decorated pottery may confirm the validity of existing cultural markers for the SGPTC.However, its low frequency points toward the need to refine the existing definitions to other ceramic traits.Other decorations suggest links to the TCC, while the overall low frequency of decoration is representative of other MBA sites in the Polish Lowlands.Since Czeladź Wielka represents one of the first documented settlement sites for the MBA in the Silesian-Greater Poland border area, we believe it will provide the basis to re-evaluate other excavated and unpublished sites to improve our current state of knowledge of the SGPTC settlement system in the region.
