An Aegean History and Archaeology Written through Radiocarbon Dates (1) Overview Context The Aegean area has so far lagged behind several other parts of Europe and the Mediterranean in not offering any major listing of its considerable radiocarbon record, despite decades of radiocarbon sampling at major sites and worldwide radiocarbon-led debates, such as over the dating of the Santorini eruption (e.g. [1–8]). The dataset provided here is the outcome of a project “An Aegean Prehistory Written in Radiocarbon Dates” and it offers the most complete list so far of published radiocarbon dates from Greece. Some 3159 14C dates from 353 sites located in Greece have been discovered or cross-checked via a combination of harmonizing records from several existing radiocarbon databases, searching original publications and checking preliminary reports from both international and Greek sources. The project was designed to complement/enhance wider research agendas considering the interplay between human population, land use and long-term environmen- tal processes, especially a Leverhulme Trust funded pro- ject known as “Changing the Face of the Mediterranean” (RPG-2015-031, PI Neil Roberts) to which the current radiocarbon data were used as part of regional case study paper ([9], for the special issue, see [10]). In a variety of contexts worldwide, the assessment of radiocarbon date- lists as aggregate times series, often via summed prob- ability distributions, has become popular for modelling human population change (e.g. [11]). Their collation with additional archaeological records, such as pollen cores and site data, has offered further opportunities to detect regional differences in the long-term socio-ecological development. Although the original aim of the project was to retrieve as exhaustive a list of published radiocarbon dates in the Aegean area from only the Mesolithic to Iron Age (ca.12–2 kya), it became evident that the number of published dates covering the area of modern Greece was far lower DATA PAPER An Aegean History and Archaeology Written through Radiocarbon Dates Markos Katsianis1, Andrew Bevan2, Giorgos Styliaras1 and Yannis Maniatis3 1 Department of History and Archaeology, University of Patras, GR 2 Institute of Archaeology, University College London, UK 3 Laboratory of Archaeometry, NCSR Demokritos, GR Corresponding author: Markos Katsianis (mkatsianis@upatras.gr) This dataset is the outcome of an INSTAP-funded project “An Aegean Prehistory Written in Radiocarbon Dates”. It includes 3159 14C dates from 353 sites in Greece and reflects an attempt to exhaustively collect and cross-check all published radiocarbon dates from existing databases, original publications and preliminary reports using both international and Greek sources (376 sources in total). Although originally targeting prehistoric dates, all dates coming from archaeological or environmental sampling were inte- grated in the final dataset regardless of chronological period. Sites have been identified and positioned as accurately as possible, while additional information on sampling procedures, sample material and strati- graphic context have been recorded. Keywords: environment; archaeology; radiocarbon dating; Greece; Holocene Funding statement: The Institute for Aegean Prehistory (INSTAP) provided the core funding for the “An Aegean Prehistory Written in Radiocarbon Dates” project which ran between 2016–2017. Previous sup- port by INSTAP to Yannis Maniatis for the radiocarbon dating of Early Neolithic settlements in Greece in NCSR Demokritos Radiocarbon Laboratory allowed for several dates to be processed and included in the present work. Work related to data cleaning and terminology mapping was implemented as part of the dataset preparation process to be ingested in the ARIADNEplus portal. ARIADNEplus (Advanced Research Infrastructure for Archaeological Database Networking in Europe) is a project funded by the European Commission under the H2020 Programme, contract no.

Four main reasons are identified for this issue: – There is a small core of radiocarbon dates especially for Aegean prehistory originally published in Eng- lish and re-used extensively in subsequent attempts by researchers to better define individual chronolog- ical subperiod boundaries, period outsets (e.g. the beginning of Neolithic) or important events (e.g. the Santorini eruption). – A substantial number of measurements (ca. 17%) come from purely or partially non-anthropic con- texts as part of investigation strategies involving boreholes towards the reconstruction of environ- mental or geomorphological conditions in the past. – In the Greek literature, there has been a marked ten- dency for archaeologists to report calibrated dates without clear reference to conventional (pre-calibra- tion) radiocarbon ages or supplementary data (e.g. context details). – Later periods (after about ~2500 BP) are under- represented (far fewer dates) due to the lack of an academic tradition in collecting radiocarbon dates for Classical, Medieval and more recent periods of archaeology. In this respect, the final dataset includes all dates encoun- tered in the literature regardless of research context (archae- ological, environmental or material conservation studies) or chronological period. Contextual information regarding the sampling procedure has also been recorded and sites have been identified and located as accurately as possible. A lot of effort has been directed towards cleaning data and refining terminology, with a view to data ingest into the ARIADNEplus portal.1 As a result, we hope that in terms of both data struc- ture and content, the current date-list aggregate will form an important radiocarbon data reference for Greece and con- tinue to grow through further input and re-use. Spatial coverage Description: The dataset covers the area of modern Greece. Figure 1 shows the study area and the distribution of sites with archaeological and environmental samples.

BC) to early modern times. (2) Methods The creation of this dataset was only possible due to the growing availability of openly available data records and relevant digital scholarship [12]. To approach the data col- lection, we combined secondary sources of already com- piled radiocarbon datasets with other available online sources than might be screened and harvested for radio- carbon data. Steps More specifically, we have extracted lists of Greek dates from available 14C date lists and databases [13–20]. The lead author further screened digital versions of original publications and paper-based sources to find new dates or check, enhance and georeference those already listed by others. Journal sources that were extensively screened include but are not limited to: Acta Archaeologica, Annual of the British School at Athens, Antiquity, Archaeological and Anthropological Sciences, Archaeometry, Bulletin de Correspondance Hellénique, BSA Archaeological Reports, Eurasian Prehistory, European Journal of Archaeology, Geoarchaeology, Géomorphologie, Hesperia, International Journal of Nautical Archaeology, International Journal of Osteoarchaeology, Journal of Archaeological Research, Journal of Archaeological Science, Journal of Archaeological Science Reports, Journal of European Archaeology, Journal of Field Archaeology, Journal of Human Evolution, Journal of the Royal Anthropological Institute, Journal of World Prehistory, Méditerranée, Mediterranean Archaeology and Archaeometry, Oxford Journal of Archaeology, PLOS One, Proceedings of the Prehistoric Society, Radiocarbon, Mediterranean Historical Review, Science, Vegetation History and Archaeobotany, Volumes of the Archaeological Work in Macedonia and Thrace annual conference, World Archaeology. All the above were checked for all those vol- umes that were available online up to 2016. Radiocarbon lists were further extracted from several monographs, chapters in edited volumes, websites and site reports. Finally, Y. Maniatis (one of the authors here) provided clar- ifications for partially published (i.e. published by archae- ologists only as calibrated timespans) radiocarbon dates from the NCSR Demokritos Radiocarbon Laboratory. Sampling strategy In addition to providing basic and alternative lab codes (stored in “LabID” and “OthLabID” respectively) as well as date codes in searched radiocarbon dating data- bases (“OtherDateCode”), conventional (pre-calibration) radiocarbon age (“CRA”) and 1-standard deviation error (“Error”), we have further collected several data fields per date containing: – isotopic fractionation of stable carbon isotopes Carbon-13 (δ13C) for allowing clear assessment of fractionations and reservoir effects, but also for understanding changing water-stress across regions and through time (“DC13”), – other measurements related to the reported data, e.g. Percent Modern Carbon (pMC) (“Oth Measures”), – notices on the technique/method used to process the sample (“DateMethod”), – basic information on the sample material (“Mate- rial”) as well as genus or species level identifications where possible (“Species”). For each date, we report its original publication and all subsequent works referencing it including online databases or publicly accessible data archives. In this respect, a considerable amount of contextual and sup- plementary information associated with each date has been included. The collection procedure focused on data quality control, by cross-checking all attributes associated with the radiocarbon dates and addressing possible inconsistencies in the published records. In cases where conflicting statements (e.g. sample age, deviation error) were encountered in the sources, we made decisions on our final database entry based on the most complete/detailed descriptions, the preference of original publications rather over compiled second- ary sources (e.g. databases), the comparison with later (paper) publications on the possibility of measurement revisions (e.g. [21]). Problematic cases are reported in the “Problems” field, while alternative measurements alongside their link to their respective references have been included in the “Comments” field, both contained in the “C14Samples” table. The geographic location of samples has been assigned Latitude/Longtitude coordinates in decimal degrees (“Longtitude” and “Latitude”) recorded under the WGS84 ellipsoid (EPSG 4326). Each location has been coded according to its perceived accuracy using four different assessment levels (A: sub-site quality +/–10 m, B: within +/–1 km, C: Moderate accuracy within Admin Region, D: Unknown accuracy within Country). In cases of large sites (e.g. Knossos) where it was possible to locate sam- ples within smaller or neighbouring research areas (e.g. Unexplored Mansion), this differentiation is also reflected in the “SiteName” field. However, the published dataset includes downgraded location coordinates that have been grouped by site name, in line with looting prevention policies by the Greek Ministry of Culture and Tourism. Researchers wishing to obtain the accurate coordinates can contact the lead author. Current Greek administrative divisions (“AdminRegion” and “Country”) have been used to group samples. In terms of contextual information, recordings include typological distinctions between site types (“SiteType”), notes on the stratigraphic context of each sample (“SiteContext”), chronological distinctions related to intra-site phasing (“SitePhase”) and broader chrono- logical periods related to the sample’s cultural context (“CulturalPeriod”). Katsianis et al: An Aegean History and Archaeology Written through Radiocarbon DatesArt. 5, pp.  4 of 6 Quality Control After the completion of the data collection stage we undertook painstaking steps in data cleaning and check- ing. To solve data discrepancies, we had to re-visit and cross-check already screened sources. In descriptive fields, such as “SiteContext”, readily available information was edited to achieve a standardized contextual notation for each site and mitigate differences in site context reporting between publications (e.g. Franchthi Cave). In fields where a term list could be established we tried to standardize entries as much as possible and map resulting terms to reference vocabularies or thesauri (see relevant tables). We used the Getty Art and Architecture Thesaurus (AAT) to map terms in the fields of “SiteType”, “Material” and “Species”. Also, the Getty Thesaurus of Geographic Names (TGN) to standardize individual entries for the “SiteName” and “AdminRegion” fields. Finally, we employed PeriodO and the Greek Historical Periods Vocabulary (URI: http:// semantics.gr/authorities/vocabularies/historical-periods) from the National Documentation Centre (NDC) [22] to further normalize the chronological periods reported in the “CulturalPeriod” field. All mappings are also being made available to ARIADNEplus to enhance data interop- erability in the ARIADNEplus portal. Constraints In every respect, the dataset remains far from ideal. For example, almost 48% of the dates do not have associated δ13C values, whereas ca. 32% are not associated with any defined chronological period. Radiocarbon dates have been reported in the literature with varying degrees of associated information. Although the most recent pub- lications are obviously more detailed, in many aspects reporting continues to vary significantly between labo- ratories or individual reports. Although, we have given a special emphasis to quality control while moving through the labyrinth of different paper and digital sources, a feel- ing persists that certain constraints rise from the original data reporting sources. In this regard, it remains up to the user to assess data reliability and proceed with appropri- ate caution. The data archive to which this paper points should be considered a versioned first release: we encour- age all users to inform the lead author of any possible errors and we will seek to produce and update a more dynamic online repository accordingly. (3) Dataset description The dataset contains a single tab delimited text file (.txt) of the 14C dates for Greece (C14Samples) plus a BibTex format bibliography (References). A further tab delimited text file has been included to document the main file fields and the domain values included in the (C14Greece_ fields). The project’s relational database was originally in MS Access and a version of this has been made avail- able as a SQL dump file containing DDL (Data Definition Language) and DML (Data Manipulation Language) que- ries for reconstructing the database (C14Greece_dump). Apart from the main C14Samples table, the full rela- tional database contained six more tables with standard- ized domain values for the following fields contained in the main table: 1) Admin Region, 2) CulturalPeriod, 3) Material, 4) SiteName, 5) SiteType, 6) Species, 7) Source. Values from tables 1 and 4 have been mapped to TGN, those of table 2 to PeriodO and NDC chronological peri- ods, while the values from 3, 5 and 6 to the AAT. Table 7 included the original transcription of the source refer- ence, which eventually resulted in the BibTeX file, but was also maintained in the original database. Object name C14Samples.txt – single file (Tab Delimited Text, UTF8 encoding) providing the data for all 14C samples. It cor- responds to the original database main table. C14Greece_fields.txt – single file (Tab Delimited Text, UTF8 encoding) containing field type definitions and domain values for all content included in the projects database. References.bib – single BibTeX file containing references cited for all 14C samples recorded. C14Greece_dump.sql – single file containing the main data table and seven additional tables for domain values and references. Data type Secondary data Format names and versions TXT UTF8, SQL, BibTeX Creation dates Most of the records were created in 2016–2017 as part of the INSTAP funded project “An Aegean Prehistory Written in Radiocarbon Dates”. Between 2019–2020 records underwent cleaning and standardization in the frame- work of the ARIADNEplus project, while a small number of additions were implemented. Dataset Creators The researcher responsible for data entry was Markos Katsianis. Online radiocarbon listings and literature sources were provided by Andrew Bevan, who supervised the data recording and standardisation process. Records were restructured, cleaned and standardized by Giorgos Styliaras. Yannis Maniatis provided additional records from the NCSR Demokritos Radiocarbon Laboratory and helped solve dis- crepancies between entries. Terminology mappings were performed by Giorgos Styliaras and Markos Katsianis. Language English. Greek literature has been included in modern Greek. Site context descriptions from Greek sources may contain Greek characters (e.g. Sector Φ). License https://creativecommons.org/licenses/by/4.0/.

(4) Reuse potential This dataset comprises the largest single collection so far of radiocarbon data for the Aegean region, covering the equivalent area of modern Greece. It provides a compre- hensive resource for accessing detailed chronological data from specific sites or wider regions within Greece. Sites have been located to the highest possible accuracy and although their coordinates have been downgraded to ca. 500 m. radius to discourage illegal uses, their positions can still be used in archaeological site mappings. The crea- tion and circulation of radiocarbon databases of this kind follows wider efforts in sharing open licensed, georefer- enced large-scale datasets in archaeology and beyond. On a broader level, the dataset allows the Greek radiocarbon listings to be added to data collections of other kinds from the Aegean region and to be used in comparative agendas of greater geographical scope. One key reuse potential relates to the use of aggregate lists of anthropo- genic radiocarbon data as a proxy for human population change, for example via summed probability distributions (SPDs). Further potential might relate to enhanced inter- pretation of Aegean prehistoric archaeological sequences at regional levels or chronological comparison between different regions. Also, the juxtaposition of large lists of radiocarbon dates with other scientific data, such as pol- len cores, macrobotanical remains, skeletal assemblages or archaeological settlement survey datasets offers further opportunities to approach long-term socio-environmental trajectories and questions.
