Keros
View on Wikipediafrom Wikipedia
Keros (Greek: Κέρος; anciently, Keria or Kereia (Ancient Greek: Κέρεια[1])) is an uninhabited and unpopulated Greek island in the Cyclades about 10 km (6 mi) southeast of Naxos. Administratively it is part of the community of Koufonisia. It has an area of 15 km2 (6 sq mi) and its highest point is 432 m (1,417 ft). It was an important site to the Cycladic civilization that flourished around 2500 BC. It is now forbidden to land on Keros.
Key Information
Keros hoard
[edit]
The "Keros Hoard" is a very large deposit of Cycladic figurines that was found on the island of Keros.
In 2006–2008, the Cambridge Keros Project, co-directed by Colin Renfrew with others, conducted excavations at Kavos on the west coast of the island.[2] This general area is believed to be the source of the so-called "Keros Hoard" of fragmentary Cycladic figurines.[3] The material excavated in 2006–2008 includes Cycladic figurines, vessels and other objects made of marble, all broken prior to deposition and most likely broken elsewhere and brought to Kavos for deposition. The lack of joining fragments shows that only a part of the broken material was deposited here, while ongoing studies of the pottery and other material show that material was brought from multiple sources for deposition here.
Daskalio
[edit]
In 2007–2008, the same project identified and excavated a substantial Cycladic period settlement on the nearby island of Daskalio that was once attached to Keros, but is now a tiny islet because of sea level rise. A large area has been excavated, revealing a substantial building 16 metres long and 4 metres wide — the largest from this period in the Cyclades — within which was discovered the 'Daskalio hoard' comprising a chisel, an axe-adze and a shaft-hole axe of copper or bronze. In addition to excavation, survey of the islet showed that most of its surface — a total of 7000 square meters — was occupied during the Early Bronze Age, making this the largest site in the Cyclades. Specialist studies for the geomorphology, geology, petrology, ceramic petrology, metallurgy and environmental aspects (botanical and faunal remains, phytoliths) ensued.
In 2012, the activities at this site were dated 2750 to 2300 BC, which precedes any identified worship of gods in the Aegean.[4]
In 2018, excavations revealed the remains of massive terraced walls and giant gleaming structures on the islet. The structures were built using 1,000 tons of stone, turning the headland, which measures just 500 feet (150 m) across, into a single, giant "step pyramid". Researchers found evidence of complex drainage tunnels and traces of advanced metalworking. The researchers say the remains make the island one of the most impressive archaeological sites of the Aegean Sea during the Early Bronze Age. The excavations show that the headland of Dhaskalio was almost entirely covered by remarkable monuments.[5] Archaeologists believe that ancient Greeks embarked on at least 3,500 maritime voyages to transport between 7,000 and 10,000 tonnes of white marble among islands, in order to construct the aforementioned pyramid.[6] Researchers said that "[t]he island is naturally pyramid-shaped, but one should not refer to the island as a pyramid — a pyramid is a completely artificial construction."[7]
Keros-Syros culture
[edit]Keros-Syros culture is named after the two islands in the Cyclades—Keros and Syros. This culture flourished during the Early Cycladic II period (ca 2700-2300 BC). Some of the best preserved sites of this culture are at Kea and Ios, located not far from Keros.
Some of the important artifacts of this culture are the so-called frying pans – shallow circular vessels or bowls with a decorated base. The use of metal became widespread during this period.

Geography
Location and Physical Features
Keros is an uninhabited island situated in the Cyclades archipelago of the Aegean Sea, approximately 10 km southeast of Naxos. Its central coordinates are 36°53′N 25°39′E. The island forms part of the Lesser Cyclades group and lies within the South Aegean region of Greece.[2] Covering an area of 15 km², Keros features a rugged, semi-mountainous terrain characterized by steep slopes, V-shaped valleys, and rocky coasts shaped by intense tectonism and erosional processes. The highest point, Mount Papa, rises to 432 m above sea level.[2] Vegetation is sparse, limited by the arid conditions and rocky substrate typical of the Cyclades, rendering much of the land marginal for agriculture.[5] Geologically, Keros consists primarily of hard crystalline limestones and marbles, with evidence of metamorphic influences common to the southeastern Cyclades, including schist formations.[6][7] These rock types have facilitated prehistoric quarrying activities, though local resources were supplemented by imports from nearby islands. The island's western coast includes the islet of Dhaskalio, approximately 0.5 km offshore, which was once connected to Keros by a tombolo-like causeway during the Early Bronze Age but has since been separated due to erosion and sea-level changes.[1] Keros lies close to other islands in the Lesser Cyclades, with Koufonisia situated about 1.5 nautical miles (approximately 2.8 km) to the northeast.[2]Administrative and Modern Status
Keros is administratively integrated into the municipality of Naxos and Lesser Cyclades as part of the community of Koufonisia, a reorganization stemming from Greece's 2011 Kallikratis Programme that consolidated local government units across the country.[8][9] The island is uninhabited, with no permanent residents or supporting infrastructure; national censuses conducted by the Hellenic Statistical Authority recorded a population of zero in 2001, 2011, and 2021.[10][11][12] To safeguard its significant archaeological remains, the Greek Ministry of Culture enforces strict prohibitions on landing and unauthorized access to Keros, requiring special permits issued through the Ephorate of Antiquities of the Cyclades; these measures, in place since the commencement of systematic excavations in the late 1980s, extend to restrictions on approaching by boat and the use of drones near the sites.[13][11][14] Preservation initiatives have intensified in recent years, with ongoing monitoring and collaborative archaeological work led by the Ephorate of Antiquities of the Cyclades in partnership with international institutions such as the British School at Athens and The Cyprus Institute, including a new excavation season conducted in 2025 to further enhance site guardianship, particularly in response to climate change-induced threats like coastal erosion affecting Greek island heritage sites.[4][15][16]Archaeological Overview
Context in Cycladic Civilization
The Cycladic civilization emerged during the Early Bronze Age in the Aegean Sea, spanning approximately 3200 to 2000 BC, and is conventionally divided into three periods: Early Cycladic I (c. 3200–2700 BC), marked by initial settlement and simple material culture; Early Cycladic II (c. 2700–2300 BC), characterized by cultural elaboration; and Early Cycladic III (c. 2300–2000 BC), which saw influences from external regions.[17] This era witnessed the islands' inhabitants developing seafaring capabilities that facilitated inter-island and broader Aegean interactions. The Early Cycladic II period, in particular, represented a peak of innovation, with expanded maritime trade networks exchanging obsidian, metals, and prestige goods; advancements in copper and bronze metallurgy, including smelting and alloying techniques; and growing ritual complexity evidenced by specialized deposits and communal gatherings.[18] These developments transformed the Cyclades from isolated communities into interconnected nodes, where sea travel enabled the distribution of raw materials from sources like Melos for obsidian and Kythnos for copper, fostering social and economic hierarchies.[19] Within this framework, Keros emerged as a pivotal sanctuary or pilgrimage center, drawing participants from across the Cyclades and beyond, as indicated by the diverse imported materials—such as obsidian from Melos, Giali, and Anatolia, and foodstuffs from nearby Kouphonisia—assembled at the Dhaskalio-Kavos site without evidence of on-site agriculture or fortification.[19] This reliance on external resources underscores Keros's role as a symbolic hub rather than a self-sustaining settlement, promoting regional cohesion through ritual activities over several centuries (c. 2750–2250 BC).[17] Archaeological assessments of the Dhaskalio structures reveal that sustaining this centrality required substantial organized effort, including over 3,500 maritime voyages between 2750 and 2300 BC to ferry 7,000–10,000 tons of high-quality white marble from Naxos, highlighting the island's profound symbolic and logistical significance in Cycladic society.[20] Unlike islands such as Naxos, with its productive quarries and cemeteries like Aplomata, or Syros, featuring fortified settlements like Kastri, Keros uniquely prioritized ritual deposition over defense or subsistence, distinguishing it as a dedicated ceremonial nexus.[19]History of Excavations
Archaeological interest in Keros emerged in the early 1960s following reports of looting at the Kavos site, prompting initial rescue excavations by Christos Doumas in 1963, which uncovered substantial quantities of broken marble figurines and vessel fragments indicative of Early Cycladic activity.[11] These findings highlighted the site's significance but were limited by the rescue nature of the work, with Doumas documenting the intentional fracturing of artifacts amid extensive illicit digging.[21] Further investigation followed in 1967 under Photeini Zapheiropoulou and Konstantinos Tsakos, who conducted a larger-scale salvage operation at the looted area, recovering over 170 additional figurine fragments and confirming the deliberate breakage patterns observed earlier.[1] These early efforts established Kavos as a key locus for fragmented Cycladic marble objects, though systematic analysis was constrained by the post-looting context.[4] Systematic excavations resumed in 1987–1988 under the direction of Colin Renfrew, in collaboration with Christos Doumas and Lila Marangou, focusing on both Kavos and the nearby Dhaskalio settlement as part of a broader Cycladic survey.[22] This campaign employed targeted trenching and surface collection, revealing evidence of intentional breakage across hundreds of marble figurines and vessels, with over 300 stone artifacts documented, underscoring ritual deposition rather than mere discard.[23] The work emphasized stratigraphic recovery to contextualize the site's chronology within the Early Bronze Age, marking a shift toward interdisciplinary methods including pottery typology and basic conservation.[24] The Cambridge Keros Project, initiated in 2006 under Renfrew's leadership with Michael Boyd as co-director, represented a major escalation in scope and methodology, conducting excavations from 2006–2008 that targeted unlooted deposits at Dhaskalio and Kavos using micro-excavation techniques for fine-grained recovery.[11] This phase uncovered multi-phase structures at Dhaskalio, including terraced buildings, and confirmed extensive hoard deposits at Kavos through precise stratigraphic excavation, integrating digital recording via total stations and GIS for spatial analysis.[21] Subsequent fieldwork included the 2012–2013 Keros Island Survey for landscape prospection and the 2015–2018 Keros-Naxos Seaways Project, which expanded to maritime networks using geophysical survey and 3D modeling to map site evolution.[25] These efforts advanced methodological standards, incorporating radiocarbon dating and residue analysis to refine chronologies without disturbing fragile contexts.[26] Following the 2018 season, the project paused due to funding constraints and the passing of Renfrew in 2024, but resumption was announced for 2025 as a five-year collaboration between the Greek Ministry of Culture's Ephorate of Antiquities of the Cyclades and the University of Cambridge, directed by Michael Boyd and funded by the Avax Group.[4] This new cycle introduces AI-assisted analysis for artifact classification and climate impact studies on site preservation, marking the Aegean's first fully digital excavation with 3D record-keeping and virtual reality integration.[27] The 2025 field season, which ran from April to June, included a training component for students and emphasized sustainable practices amid rising sea-level threats, successfully marking the beginning of the five-year research programme, with plans announced for a further season in 2026.[16][1] Throughout these investigations, excavations have grappled with the legacy of 1950s–1960s looting, which dispersed thousands of Keros fragments into international collections, including the National Archaeological Museum in Athens, where Cycladic figurine pieces from Kavos form part of the permanent display.[28] Ethical debates over repatriation persist, with Greek authorities advocating for the return of looted items from private holdings and foreign museums to reconstruct site contexts, as seen in broader Cycladic repatriation efforts since the 2010s.[29] These challenges have informed project protocols, prioritizing non-invasive documentation to mitigate further loss.[1]Dhaskalio-Kavos Site
Dhaskalio Settlement
Dhaskalio is a low-lying rocky islet located off the western coast of the island of Keros in the Cyclades, Greece, which during the Early Bronze Age was connected to the adjacent Kavos area on Keros by a narrow causeway due to lower sea levels at the time.[30] The site hosted a multi-phase settlement spanning approximately 2750–2300 BC, representing the largest known Early Cycladic settlement in the Cyclades, covering approximately 1.3 hectares (13,000 m²) and serving as a hub for residential, productive, and possibly communal activities.[31][32] The settlement's architecture demonstrates advanced planning and construction techniques, featuring terraced multi-level complexes built with massive retaining walls of limestone boulders and imported high-quality marble, primarily sourced from the nearby island of Naxos.[25] Key structures include a monumental hall-like building at the summit, measuring 16 m in length and 4 m in width, alongside integrated stone stairways and sophisticated drainage systems that facilitated the site's terraced layout across a steep incline.[30] This engineering is exemplified by a step-pyramid-like mound formed by over 1,000 tons of quarried stone, which supported the upper terraces and may have served ritual or communal functions within the broader landscape that included nearby ritual activities at Kavos.[33] Archaeological evidence points to specialized craft production at Dhaskalio, particularly in metalworking, with the discovery of a hoard comprising at least three copper or bronze tools—a chisel, an axe-adze, and a shaft-hole axe—likely made from arsenical copper, found within the summit building.[30] These artifacts, along with associated smelting debris and a stone mold for casting daggers, indicate on-site production using imported ores and highlight Dhaskalio's role in regional trade networks for high-status metal goods during the Early Bronze Age. Excavations continued from 2015 to 2018, revealing further details on architecture and metallurgy, with a new five-year program commencing in 2025.[31][16]Kavos Ritual Area and Keros Hoard
The Kavos promontory on the island of Keros, located in the Cyclades archipelago, features no evidence of buildings or permanent habitation but is characterized by intentional deposits of fragmented artifacts, including shattered marble vessels and hundreds of figurine fragments, uncovered during systematic excavations from 2006 to 2008 by the Cambridge Keros Project.[21][20] These deposits, particularly the Special Deposit South, consisted of over 53,000 pottery sherds, more than 2,200 marble vessel fragments, and approximately 500 marble figurine fragments, all placed in structured layers without signs of domestic activity.[20][34] The Keros Hoard, comprising these excavated materials alongside earlier looted artifacts, includes abstract female figurines of the folded-arm type, incised marble discs known as "frying pans," and rolled-rim bowls, with pieces sourced from various Cycladic islands based on marble provenance analysis.[34][21] The artifacts were deliberately broken prior to transport and deposition around 2700 BC during the Early Cycladic II period, as evidenced by the absence of joining fragments within the deposits themselves, indicating off-site fragmentation events.[20][21] Scholars interpret Kavos as an early maritime sanctuary dedicated to ritual breakage practices, where the intentional shattering of high-status items symbolized offerings or the decommissioning of sacred objects, rather than accidental damage or utilitarian discard.[20][34] The lack of human remains, tools, or structural remains further supports its role as a non-residential ritual locus focused on ceremonial deposition.[21] This site represents the largest known deposit of Early Cycladic figurines and marble vessels, underscoring Kavos's role as a pan-Cycladic ceremonial center that facilitated inter-island gatherings and exchange, thereby challenging traditional notions of isolated island communities in the prehistoric Aegean.[20][34] The hoard's diverse origins and scale highlight emerging social complexity and shared ritual traditions across the region around 2700 BC.[21]Keros-Syros Culture
Chronology and Characteristics
The Keros-Syros culture, a pivotal phase of the Early Cycladic civilization, spans the Early Cycladic II period, roughly from 2700 to 2300 BC. It succeeded the Grotta-Pelos culture of Early Cycladic I (c. 3200–2700 BC), which featured simpler schematic artifacts and smaller-scale settlements, and preceded the Kastri phase of Early Cycladic III (c. 2300–2000 BC), marked by fortified sites and broader Aegean interactions. This chronology is established through radiocarbon dating of settlement layers and grave goods across the Cyclades, with key sites like Dhaskalio on Keros providing stratified evidence of continuous occupation during this span.[35][36] Core characteristics of the Keros-Syros culture reflect technological and cultural advancements, including the widespread adoption of metallurgy, evidenced by the production of bronze tools, weapons, and ornaments sourced from local ores on islands like Seriphos and Siphnos. Pottery evolved to include incised fine wares, notably the distinctive "frying pans"—shallow, circular vessels with symbolic motifs such as spirals, ships, and abstract female symbols scratched into the surface before firing, often interpreted as ritual or astronomical representations. Marble figurines, typically stylized female forms with folded arms, became emblematic, produced in specialized workshops and distributed via maritime networks. Unlike preceding phases reliant on subsistence agriculture, the culture emphasized maritime exchange, with longboats facilitating trade in obsidian, metals, and ceramics across the Aegean, fostering interconnected island communities rather than intensive land-based farming.[37][38][39][40] Social organization during this period shows signs of emerging hierarchy, inferred from the concentration of specialized production—such as marble carving and metalworking—at select sites, and the role of ritual centers like Kavos on Keros, where fragmented prestige items suggest communal ceremonies reinforcing elite status. The population was distributed in small, dispersed settlements of 50–100 people each, supported by marine resources and inter-island mobility rather than large agricultural surpluses.[41] The culture's decline around 2300 BC may have been influenced by environmental shifts such as aridification and soil degradation in the broader Aegean region, as suggested by paleoclimatic records from Greece, potentially compounded by external influences like increased contacts with Minoan Crete or Anatolian groups disrupting trade networks. This transition is marked by the abandonment of major unfortified sites and the rise of defensible settlements in the subsequent Kastri phase, signaling a shift toward more insular, protective strategies.[42]Key Artifacts and Influence
The Keros-Syros culture is renowned for its iconic marble idols, typically stylized female figures with folded arms across the chest, measuring up to 50 cm in height and carved in a schematic, abstract style that emphasizes geometric forms over naturalistic details.[43] These figurines, often featuring incised lines for facial features or body markings, represent a pinnacle of Early Cycladic artistry. Complementing them are the distinctive "frying pans," shallow ceramic vessels approximately 20–30 cm in diameter, incised on their interiors with motifs such as spirals, ships, and possibly solar or lunar symbols, which may relate to astronomical observations or fertility rituals.[44] Early bronze items, including daggers with triangular blades, further exemplify the culture's material repertoire, crafted from copper alloyed with arsenic to enhance hardness and durability.[45] Production techniques reflect sophisticated craftsmanship, with idols fashioned from fine-grained Naxian marble quarried on Naxos, shaped through abrasion and polishing rather than chiseling to achieve smooth surfaces. Incising on frying pans and other objects was accomplished using sharp obsidian tools, sourced from Melos, allowing for precise geometric engravings.[36] The bronze daggers involved smelting copper with arsenic, a process that produced a harder alloy suitable for weapons, marking an early adoption of arsenical bronze in the Aegean.[46] Stylistic motifs from the Keros-Syros culture, particularly the folded-arm pose of figurines, spread to Minoan Crete during Early Minoan II (c. 2700–2400 BC) and to the Helladic mainland thereafter, influencing local workshops in the creation of similar anthropomorphic sculptures.[47] This dissemination is evident in shared iconographic elements, such as abstracted female forms, which appear in Cretan terracotta figures and mainland grave goods, fostering broader Aegean artistic interconnections. The culture's artifacts have also played a significant role in modern perceptions, with marble idols becoming emblematic of Cycladic abstraction and inspiring 20th-century artists like Henry Moore, while fueling debates on authenticity in museum collections due to widespread looting.[48] A hallmark unique to Keros within this culture is the concentration of deliberately broken artifacts, including hundreds of shattered marble idols and vessels, interpreted as evidence of "killing" rituals where objects were ritually decommissioned before deposition.[49] This practice contrasts sharply with domestic sites like Chalandriani on Syros, where intact items predominate in burials, underscoring Keros's specialized role in ritual activities. The depositional context at Kavos exemplifies this, with fragments transported from across the Cyclades for intentional breakage and burial.[11]References
