IntroductionThe site of Monte d’Accoddi is to be found in north-western Sardinia, 3.4 km to the south of Platamona beach (Figure 1). The earliest feld investigations were carried out by Ercole Contu between 1952 and 1959. His work brought to light the most recent of the two monuments, which was built from large polygonal stone blocks. The excavation of the surrounding area led to the discovery of a village of quadrangular dry-walled huts (Figures 1–3). An examination of the fnds led him to attribute the construction of the monument to the frst phase of the Ozieri cultural facies (frst half of the 4thmillennium cal. BC). Finds of more recent dates are evidence of occupation in later phases of prehistory, whereas a stone ring may indicate earlier sporadic occupation during the Early or Middle Neolithic (Contu, 1992; 2000).A second series of feld investigations was carried out between 1979 and 1989. These were followed by large-scale rebuilding and restoration of the monument (Figure 2), implemented on the basis of a hypothetical reconstruction by Santo Tiné, who had directed the stratigraphic excavations. The most important discovery was the identifcation, within the monument itself, of a more ancient building, featuring red-painted wall plaster and with its own ramp, and containing at its summit, a rectangular sacellum. Also of great signifcance was the acquisition of six radiocarbon dates, which have enlivened the debate over the chronology of the construction phases (Tinè and Traverso, 1992).More recent studies include those undertaken by Antonella Traverso on a portion of the pottery fnds recovered during the excavations directed by Tinè. These studies contributed to the interpretation of the stratigraphic sequence, as well as identifying morphological and technological characteristics of the fnds themselves (Traverso, 2005–2007).The earliest research by the author of this paper was aimed at the morphological and typological study of pottery fnds from Hut p-s, attributed to an occupation phase of the 3rdmillennium cal. BC. Subsequently this research has been extended to all of the fnds recovered during the excavations directed by Ercole Contu, as part of a project aimed at: the overall analyses of stone, clay, hard animal materials and metal artefact production processes; defning the chronology of the building and its various phases of use; and the reconstruction of the character of the settlement that developed around this central monument.As the radiocarbon results published by Tinè and their subsequent interpretation were inconsistent with the chronological and cultural framework of Sardinian Volume XIV     ●     Issue 1/2023     ●     Pages 31–40*Corresponding author.

BC. The building comprised of a terrace with an access ramp, a form that has led to an ongoing debate as to the possible origins of this architectural model. In its earliest phase, attributable to the frst half of the 4th millennium cal. BC, the edifce consisted of a truncated pyramidal core. During the second half of the same millennium this was englobed by a second building, similar to the frst in general shape, but much larger and with a central, possibly stepped, core. The site was occupied during the 3rdmillennium cal. BC and occasionally so during the following proto-historic and subsequent phases of history. This paper will present new radiocarbon dates that will help to defne the construction and occupation phases of the monument as well as the settlement that grew around it.

In the same way, the Early Eneolithic ceramics are the latest fnds in the formation layers of the second monument and therefore represent the terminus ad quemfor that building. Examination of the archive documentation (site logs, sketches, drawings and photographs) and the accessible fnds in the museum storerooms using a morphological-typological approach, made it possible to reconstruct the frequentation phases of the shrine before, during and after the construction of the ramped monument (Melis, 2011).This paper forms part of that project and is aimed at providing a more precise understanding of the construction and occupation phases of the monument and the surrounding settlement.2. MethodologyThe principal difculties with this type of fnds analyses have been, and remain, those that often concern the contexts from earlier excavations. These have included: reviewing site documentation, interpreting stratigraphy, recovering and identifying fnds, and accessing the fnds in the storerooms of the Museum and the Archaeological Soprintendenza. An important aid to the research was the examination of the existing archive and iconographical documentation. A valuable resource was provided by the sketches, often Figure 3.

Samples of the animal remains were taken for radiocarbon analyses. These were subjected to accelerator mass spectrometry (AMS) at the Centro di Datazione e Diagnostica(CEDAD) at the Università del Salento(Lecce). The dates were calibrated in OxCal v.4.4.4 using the IntCal20 atmospheric curve (Reimer et al., 2020; Bronk Ramsey, 2009; 2021).The sampling strategy took into consideration the excavation methods employed by Contu: the area surrounding the monument was divided into trenches, each of them then subdivided into sectors (Figure 3). The excavation was subsequently carried out through artifcial “levels” and not through single-context stratigraphy. This remains the foremost problem concerning the stratigraphical data. In each trench at least 8 levels were indicated (in some cases as many as 10). However, as these were artifcially created levels, there was not necessarily any correspondence between levels from one trench to another. In order to identify the earliest occupation phases of the area, samples were taken from the deepest levels, where this possibility existed. Trench X, among those containing the most fnds, was chosen for the acquisition of dates from samples in stratigraphic order. Unfortunately, not all the levels in the same sector contained animal remains, making it necessary to look at diferent sectors of the same trench and even to other trenches, while being fully aware of a possible lack of correspondence. Contemporaneously the fnds data and the stratigraphic relationships were examined and compared to the radiocarbon dates.3. ResultsSeventeen samples were analysed. They were collected from the following trenches: I, III North sector; VI East sector; X South sector; North and subsector III; XI East sector; XII (Table 1). For the samples taken from trenches I and XII the documentation did not specify a sector. Two of the samples did not deliver any results.Seeing as how sample LTL19206A, taken from level 8 of trench X-N, gave an incongruous result (a more recent dating than the one recorded for level 6), the reading was repeated on a second sample (LTL20014A) from the same level, sector and trench (Table 1. H). The second dating is consistent with the associated fnds. These are reliably referable to Ozieri I, being comparable to material from other contexts also datable to the frst half of the 4thmillennium cal. BC.In the same way, as the dating of sample LTL19205A, taken from level 7 of trench X-N-III, provided a result too recent with respect to its stratigraphical position, the dating was repeated on another sample (LTL20013A) taken from the same place (Table 1. I). This level yielded pottery fragments relating to Ozieri I (associable to the most ancient dating), Ozieri II and to the Final Eneolithic.A further incongruous result came from X-8-N-III (Table 1. J): in level 8 the excavation revealed the presence of a layer of ash (which gave the date LTL19208A), overlying a layer (date LTL20018A), which, based on the radiocarbon dating, was more recent than that of the layer above.The examination of such incongruities, together with the analysis of the fnds, made it possible to verify the degree of stratigraphical reliability of the various sectors, and in some cases has confrmed instances of disturbance. For example, a stratigraphical irregularity recorded in X-8-N datable to the 3rd millennium is confrmed by the presence of a pottery fragment belonging to the same vessel as a fragment found in level 7. In summary, it seems possible that the most recent dates evidence disturbances of the stratigraphy, perhaps due to animal burrowing leading to fnds being dragged or slipping into lower layers. The dates associated with disturbed layers, while little use for dating those same deposits, can be important however in confrming occupation of the shrine over the timespan that they represent.The results confrmed the occupation of the site from the last centuries of the 5thmillennium cal. BC through to the end of the 3rdmillennium cal. BC. The most ancient dating (Table 1. C) was recorded in the lowest level of trench III, sector N. This was attributable to a Late Neolithic settlement (the San Ciriaco cultural facies). The Final Neolithic, to which the construction of the frst ramped monument is dated, is amply documented both by fve radiocarbon dates (Table 1. A, E, H-LTL20014A, I-LTL20013A, J-LTL19208A) and by a notable quantity of fnds. These were present in almost all the levels. Three dates (Table 1. G, J-LTL19208A, L), relative to the middle centuries of the 4thmillennium cal. BC, correspond to a transition phase between the Neolithic and the Eneolithic. The Early Eneolithic, during which the second ramped monument was built, is documented by three dates (Table 1. B, D, F). Lastly, three dates confrm occupation of the site during the Middle (Table 1. K), Late (Table 1. H-LTL19206A) and Final Eneolithic (Table 1. I-LTL19205A).4. DiscussionThe radiocarbon dates are representative of all the occupation phases of the shrine, as identifed by the study of the fnds, with the exception of occasional frequentation, documented by fnds relating to the Bronze Age and the subsequent historical period. The earliest human presence
image/svg+xmlIANSA 2023 ● XIV/1 ● 31–40Maria Grazia Melis: The Chronology of Monte d’Accoddi (Sardinia, Italy) – New Radiocarbon Dates36may possibly be represented by the fnd of a schist stone bracelet (Figure 4). This was found together with a few pottery fragments referable to the cultural facies of the 3rdmillennium cal. BC in Level 4 of Trench IX, East sector, which did not provide any radiocarbon dates. This class of fnd is generally attributed to the Early or Middle Neolithic, the period to which fnds of similar rings in Europe, continental Italy and in Sardinia are principally ascribed (Ribero, 2017; Pétrequin et al., 2019; Martinez-Sevillaet al., 2021). However, very often these artefacts have been found out of context and their chronological-cultural attribution, if arrived at on a purely morphological-typological basis, could be considered unreliable. In fact, type AB2, to which group the Monte d’Accoddi example belongs (Tanda, 1977), is represented in Italy by 6 stone bracelets, referable to diverse chronological-cultural contexts, spanning the Early and Recent Neolithic (Ribero, 2017).Sardinian stone bracelets have been found in 12 sites: for 5 of these there is no chronological-cultural indication as to the context they were found in. Only the bracelet from Filiestru originates in a layer attributable to an advanced phase of the Early Neolithic (5300–4900 cal. BC). The artefact from Nostra Signora del Buon Cammino was a surface fnd recovered with material from the Early and Middle Neolithic. In other cases, an attribution to the Middle Neolithic has been suggested (4900–4400 cal. BC), but this remains unconfrmed due to a lack of diagnostic fnds or because they were recovered together with fnds from later periods. Of particular relevance is the exemplar from Liscia Pirastru, which had evidence of occupation during the Final Neolithic (4000–3400 cal. BC) and possible evidence of frequentation during the Late Neolithic (4000–3400 cal. BC). Therefore chronologically, Sardinian stone bracelets existed between the Early and Final Neolithic. Thus, we cannot exclude an attribution of the bracelet from Monte d’Accoddi to the Late or Final Neolithic, phases that are well represented both through dating and fnds at Monte d’Accoddi. This dating appears more convincing, especially considering that no fnds pre-dating the Late Neolithic were recovered.In view of this, a comparison with the chronology of Corsican bracelets becomes interesting, even if only one example has a similar shape to that from Monte d’Accoddi. However, drawing a comparison is necessary, considering the strong relationship that developed between Sardinia and Corsica during the Neolithic, as testifed by the circulation of raw materials, by the shared funerary model of the cofre, and by the spread of formal models in the feld of pottery production. In Corsica stone bracelets have been found in 12 sites, localised mainly in the south of the island. As in the case of Sardinia, in many instances there is no information as to the context they were found in, or they were recovered in multi-phase sites without a clear cultural association. Furthermore, two cases of transformation and reuse as pendants are known in the ambit of the Eneolithic at Terrina IV (Camps, 1988) and during the Bronze Age at Castiddacciu (Jehasse, 1980). Nevertheless, in 50% of the fnds the context in which they were recovered is ascribable to the Corsican Middle Neolithic II: the cofre burials at Tivulaghju (cofreB; Tramoni et al., 2007) and Foce (Pasquet, 1979), the rock shelters at San Ciprianu (Tramoni, D’Anna, 2016) and Torre d’Aquila (Magdaleine, 1995), the open-air settlements of Pastini-Foce (Tramoni et al., 2007) and A Guaita (Lorenzi, 2021). The Corsican Middle Neolithic II began around 4400 cal. BC, at the same time as the Late Neolithic was beginning in Sardinia (the San Ciriaco cultural facies) and ended around 3900 cal. BC, when the transition to the Final Neolithic had already happened in Sardinia (the Ozieri I cultural facies).The integration of the results of the new dating at Monte d’Accoddi with those previously published dates, with the stratigraphical context together with the study of the fnds has made it possible to defne the occupation sequences of the shrine more accurately (Figure 5; Table 2), as illustrated.4.1 Phase 1 (Late Neolithic)This phase is represented by a settlement at Monte d’Accoddi, typifed by the substructures identifed by Tiné in diverse areas (Tinè and Traverso, 1992). Pottery fnds recovered by Contu in numerous levels as well as in a trial trench dug roughly 90 m to the NE of the monument can also be assigned to this period. The San Ciriaco cultural facies, documented across the whole of Sardinia in the period between 4400 and 4000 cal. BC, was involved in the phenomenon of the earliest megalithic funerary monuments, consisting of cofressurrounded by stone circles.

BC. The presence of Sardinian obsidian, and of pottery bearing formal characteristics analogous to those of San Ciriaco, confrm the existence of a strong relationship between the two islands. From a terminological point of view, in Corsica the period between 4900 and 4400 cal. BC is entitled Middle Neolithic I, and that between 4400 and 3900 cal. BC Middle Neolithic II. For the Sardinian San Ciriaco cultural facies,the term Late Neolithic is preferable, as several elements suggest it should be considered a distinct phase and not a sub-phase of the Middle Neolithic. These include the apparition of megalithic cofresand the rock-cut tombs known as domus de janas.Figure 5.Complete list of the radiocarbon dates.

BC (phase 2a) a settlement attributed to the Ozieri I cultural faciesexisted at Monte d’Accoddi, in a period of demographic growth and technological development in the feld of the transformation of raw materials and architecture in Sardinia. This phase also corresponds to the period of maximum exploitation and difusion of Sardinian obsidian both in Sardinia and in the western basin of the Mediterranean.In this cultural scenario the frst ramp-and-terraced monument was built and the settlement that surrounded it continued to be occupied (phase 2b). The existence of a sub-phase of occupation during the Final Neolithic, before the building of the frst monument, is demonstrated by the presence of diagnostic pottery in the formation layers of the edifce.The positioning of a menhirto the west of the ramp may have occurred in this or in the preceding phase. The dating resulting from the area of the menhir (Figure 5, UZ-475/ETH4716) cannot be attributed to the erection of the monolith, which from a stratigraphical point of view is older than the second monument, but rather to the occupation of the Early Eneolithic settlement, of which several substructures were found to the west of the ramp, near to the area of the menhir.4.3 Phase 3 (Final Neolithic – Early Eneolithic)The transition phase between the Neolithic and the Eneolithic at Monte d’Accoddi is represented by four dates that correspond to a period of occupation of the shrine before the second monument was built. The extraordinary fnd of a sperm whale tooth (Table 1.L) belongs to this phase, adding to the number of attestations of this type of cetacean in the prehistoric Mediterranean (Melis and Zedda, 2021). The transition from the Neolithic to the Eneolithic is well documented in the settlement at Su Coddu/Canelles Table 2.  Occupation timeline of the shrine.PhaseAgeCultural faciesType of occupation1Late NeolithicSan CiriacoSettlement.

Sporadic occupation9Historical AgeVarious periodsSporadic occupation(southern Sardinia) in Pit 134, from which pottery, stone and hard animal material fnds were recovered. These had intermediate morphological and technological characteristics between the Final Neolithic and the Early Eneolithic, with a dating ranging between 3630 and 3371 cal. BC (LTL2930A, 4708 ± 45 BP, 3630-3556 [22.6%], 3538-3482 [23.2%], 3476-3371 [49.6%] cal. BC; Melis, 2013).4.4 Phase 4a-b (Early Eneolithic)At the beginning of the Eneolithic the frequentation of the oldest monument is confrmed by fnds of diagnostic pottery on the foor of the sacellum, positioned at the summit of the building. The existence of a sub-phase of frequentation during the Early Eneolithic (phase 4a) before the construction of the later building is also established by diagnostic pottery fnds in the formation layers of the second monument. A large-scale rebuilding intervention was made necessary by structural instability (phase 4b): the building was incorporated into a larger structure possessing similar general characteristics.Several elliptical substructures relative to an Early Eneolithic settlement were brought to light during the excavations run by Tiné to the west of the ramp.4.5 Phases 5 and 6 (Middle and Late Eneolithic)Occupation during the 3rdmillennium cal. BC was formerly only attested by fnds and building remains to the east of the monument, that are stratigraphically later than the monument. It is now confrmed by the radiocarbon dates. The frst is attributable to the Filigosa cultural facies of the Middle Eneolithic (Table 1.K). The presence of pottery fnds belonging to the Monte Claro cultural faciescould also be attributed to this and/or to the succeeding phase: this is based on radiocarbon dates from other sites, developing over a long period between the Middle and the Late Eneolithic.
image/svg+xmlIANSA 2023 ● XIV/1 ● 31–40Maria Grazia Melis: The Chronology of Monte d’Accoddi (Sardinia, Italy) – New Radiocarbon Dates39The second date (Table 1.H), therefore, may be ascribable to this cultural facies or to the coeval Abealzu. The important context of Hut p-s, situated to the north-east of the monument, is attributable to the latter. Interestingly, it was destroyed by fre, preserving intact evidence of its last phase of existence. Unfortunately, the context was not datable, as none of the available fauna remains came from the hut itself.4.6 Phase 7 (Final Eneolithic)Occupation during the Final Eneolithic, recognisable by the presence of fnds attributable to Bell Beaker (Melis, 2019), is also confrmed by a date (Table 1.I), which partially overlaps the Late Eneolithic. This characteristic conforms to the picture presented by the few existing radiocarbon dates for the second half of the 3rdmillennium cal. BC, which makes it impossible to identify a clear delimitation between the Late and the Final Eneolithic. The limited number of fnds implies an infrequent occupation of the shrine. However, the presence of Bell Beaker material at Monte d’Accoddi may have begun earlier, as suggested by pottery fragments typical of the international style and by formal similarities with pottery belonging to the other cultural facies of the 3rd millennium cal. BC. This hypothesis may also be supported by the dating of the Bell Beaker site at Bingia ‘e Monti (Perra and Lai, 2020). In particular the most ancient of these dates (MAMS26891, 3984±29 BP, 2578–2456 cal. BC 2σ), if not attributable to the construction phase and earliest use of the tomb, ascribed to Monte Claro, would make it possible to backdate by about a century the presence of Bell Beaker in Sardinia. However, considering the meagre evidence available, it remains necessary to await eventual confrmation through dates obtained from radiometric and stratigraphical data.4.7 Phases 8 and 9 (Bronze Age and Historical Age)From the end of the 3rdmillennium cal. BC the frequentation of the shrine became sporadic and remains unverifed through radiocarbon dates. An infant burial, containing grave goods of a tripod vase and a bowl, is attributable to the frst phase of the Early Bronze Age, between the end of the 3rdand the beginning of the 2ndmillennium cal. BC. A few scarce pottery fragments are attributable to the Middle and the Final Bronze Age. Lastly, the Historical Age yielded fnds from various periods: a glass bead, pottery fragments and several coins.5. ConclusionThe data presented here leads us to several considerations. The radiocarbon dates seem to suggest a continuity in the use of the shrine and the gradual nature of the transitions from one phase to another. For the most part the dates are attributable to the 4thmillennium cal. BC, during which the two building phases of the monument can be placed. The analysis of the fnds, still underway, shows an abundance of material relative to this period. This perhaps indicates that it corresponds to the most intense period of frequentation of the area.The fnds are evidence of the observation of ritual practices and activities connected to the economy of production and to the transformation of raw materials (Melis, 2020). The enormous quantity of animal remains discovered during the course of the excavations run by Contu, as well as in successive campaigns, may be the result of consummation during community gatherings, feasts and ceremonies, etc.These activities, together with the singular architecture of the shrine (evidently the fruit of collective efort) suggest that it served as a reference point in an intensely occupied territory, perhaps for the whole island, an identifying symbol of an afuent and cohesive society. This could be compared to the model of “pre-state cooperative afuent societies”, which manage their own “surplus gain” in specifc activities (such as the construction of a communal monument, collective feasting and the development of artisanal production) preventing its transformation into “surplus proft” (Risch, 2018).An outdated hypothesis, still dear to some scholars, that the ramped building had oriental origins, inspired by the ziqquratmodel, has no scientifc confrmation. With the exception of the ramp, the edifce possesses diferent architectural characteristics, something also true of the building methods. The chronology of Monte d’Accoddi appears, if anything, compatible with that of the terrace buildings considered prototypes of the ziqqurat (Butterlin, 2013). However, there is no proven evidence of relationships between Sardinia and the Near East in the 4thmillennium cal. BC, such as genetic data, exogenous fnds or raw materials. On the contrary, relationships in the sphere of the western Mediterranean are well documented by the circulation of obsidian and by the difusion of megalithic monuments. When the frst megalithic monuments appeared in Sardinia, in western Europe large funerary monuments with mounds were being built, some of which were stepped structures (Giot, 1987). These were sometimes (Laporte et al., 2002) assembled using a system similar to that of the “cassoni”at Monte d’Accoddi: a series of large rectangular dry-stone boxes, which were then flled and covered by the mound of the second monument. Also in this case, they represented a diferent type of monument, that, furthermore, was part of a cultural phenomenon with which Sardinia came into contact in its most southern and Mediterranean facets.Thanks to the new radiocarbon dates presented here, the frequentation of the 5thand the 3rdmillennia cal. BC are identifed, for the frst time, in terms of absolute chronology. During the 3rdmillennium cal. BC, the shrine was still occupied by a stable community, as demonstrated by the huts to the east of the monument, although perhaps by fewer people compared to the preceding millennium. In this new cultural scenario, which on a regional scale showed a growth in social inequality and territorial competitiveness, the structure built at the base of the ramp seems likely to have been used to control access to the summit of the monument. In this cultural panorama the fre that destroyed Hut p-s may be evidence of the fnal event before the shrine was abandoned.
