The Condition of Contemporary Murals in Sun-Exposed Urban Environments
The present work investigates the physicochemical stability of spray paints when irradiated with artificial solar light (at spectral range 300–800 nm). This research highlights the importance of understanding the materials used in street art and public murals, recognising them as a significant component of contemporary cultural heritage. By examining the stability and degradation of spray paints toward solar light exposure, the study aims to cont…
Radiocarbon dating of samples connected to rock-cut features at Myrina Kastro (Lemnos Island, Greece) and calculation of the regional marine reservoir effect in the Late Bronze Age in the Aegean Sea
The Kastro peninsula constitutes the extension towards the West of Myrina, the Lemnos capital, on the western coast of the island, in the North Aegean Sea. The ongoing research project on rock-cut features and rock-art of this complex site included a five-year (2002–2007) subsurface investigation, during which, among other mobile finds, charcoal and seashell samples were also collected, associated in situ to rock-cut features. Subsequently, in an…
A Middle Neolithic Pottery Workshop at Magoula Imvrou Pigadi, at the Crossroads of Eastern-Western Thessaly and Phtiotida
This paper presents the first known and systematically excavated Middle Neolithic pottery workshop in southwestern Thessaly at Imvrou Pigadi. The excavations and in situ finds, along with the pronounced kiln structures, their typological classification and pyrotechnological operation, suggests considerable expertise in pottery manufacture. The pottery itself, together with the chipped stone industry and other small finds, as well as the fauna and…
Colourful earth
The red, brown, yellow and green pigment lumps from the Hellenistic pigment production site of the ancient agora of Kos (Dodecanese, Greece) are the focus of this paper. A selection of pigments is examined through a combination of analytical techniques, including SEM-EDS on uncoated samples, X-ray powder diffraction, FTIR and pRaman spectroscopy. Through the study of raw pigments deriving from the context of a production site, the aim is to appro…
Neolithic Thessaly
Thessaly in Central Greece is famous for settlement mounds (magoules) that were already partly formed in the Early Neolithic period. Some of these long-lived sites grew to many metres in height during the subsequent Middle, Late and Final Neolithic periods, and were also inhabited in the Bronze Age. Such magoules served as the backbone for defining relative chronological schemes. However, their absolute dating is still a topic of debate: due to…
Radiocarbon Dating of the Architectural Parts of the Middle Byzantine Monastery of Hosios Loukas, Boeotia, Greece
The Monastery of Hosios Loukas is situated at an altitude of 430 m (38°23′43.12′′N, 22°44′48.22′′E) in the western foothills of Mount Helikon, near the village of Steiri, Boeotia, Greece. It is one of the most important monuments of Middle Byzantine art and architecture and has been recognized by UNESCO as a World Heritage Site. Information varies concerning the construction date of the magnificent church to house the Hosios Loukas relics. Moreov…
The Cave of Pan, Marathon, Greece—AMS Dating of the Neolithic Phase and Calculation of the Regional Marine Reservoir Effect
The Cave of Pan is located on the N/NE slope of the hill of Oinoe (38°09′31.60′′N, 23°55′48.60′′E), west of modern Marathon. In rescue excavation campaigns during the last three years, among other finds, charcoal and seashell samples were also collected. The purpose of this study is the accelerator mass spectrometry (AMS) dating of the cave’s anthropogenic deposits and the calculation of the regional marine reservoir effect during the Neolithic p…
Sea Surface Radiocarbon Reservoir Age Changes in the Aegean Sea from about 11,200 BP to Present
Archaeological excavations in two coastal sites of Greece, Ftelia on Mykonos and Cyclops Cave on Youra, have provided suitable material (charcoal/marine mollusk shell paired samples deposited simultaneously in undisturbed anthropogenic layers) to estimate regional changes of the sea surface radiocarbon reservoir effect (ΔR) in the Aegean Sea. Moreover, pre-bomb 14 C ages of marine mollusk shells of known collection date, from Piraeus and Nafplion…
Radiocarbon Dating of the Neolithic Lakeside Settlement of Dispilio, Kastoria, Northern Greece
Dispilio is the only excavated Neolithic lakeside settlement in Greece. Archaeological research provided evidence that the site was continuously used from the Early Neolithic (∼6000 BC) to the Late Chalcolithic period (∼1200 BC, Mycenaean period). During several archaeological campaigns, a portion of the settlement has been excavated that enabled a sufficient understanding of the architectural layout of homes, the building materials, and the orga…
Interpreting Radiocarbon Dates from the Paleolithic Layers of Theopetra Cave in Thessaly, Greece
Theopetra Cave is a unique prehistoric site for Greece, as the Middle and Upper Paleolithic, Mesolithic, and Neolithic periods are present here, bridging the Pleistocene with the Holocene. During the more than 20 yr of excavation campaigns, charcoal samples from hearths suitable for 14 C dating were collected from all anthropogenic layers, including the Paleolithic ones. Most of the samples were initially dated using the ABA chemical pretreatment…
Interpreting Radiocarbon Dates from Neolithic Halai, Greece
Archaeological investigations at Halai, a small city-state on the sea coast of East Lokris in Greece, have been carried out since 1986 by the Cornell Halai and East Lokris Project (CHELP). The town's acropolis, first inhabited in the Neolithic period, was in Greco-Roman times a political and cultural center controlling and serving a considerable territory. Radiocarbon dating of charred material unearthed from Neolithic deposits indicate that the …
Palaeoenvironments and site formation processes at the Neolithic lakeside settlement of Dispilio, Kastoria, Northern Greece
Dispilio is a lakeside settlement by the Orestias Lake, Kastoria, northern Greece. The site was inhabited from the Middle Neolithic to the Chalcolithic, with some surface evidence of Bronze Age occupation. Microfacies analysis of the sediments, supported by a suite of environmental indices, has provided detailed paleoenvironmental data and elucidated the main processes involved in the formation of the site and its history of occupation. The settl…
The Cave of Theopetra, Kalambaka
The cave of Theopetra is located on the northeast side of a limestone rock formation, 3 km south of Kalambaka (21°40′46′′E, 39°40′51′′N), in Thessaly, central Greece. It is a unique prehistoric site for Greece, as the Middle and Upper Paleolithic, Mesolithic, and Neolithic periods are present here, bridging the Pleistocene with the Holocene. Several alternations of the climate during the Pleistocene are recognized in its stratigraphy. Among the m…

Study of the Parameters Affecting the Correlation of Background Versus Cosmic Radiation in Co 2 Counters
Systematic treatment of the data recorded by our guard counters and corrections introduced for meteorological factors has allowed observations on solar events clearly manifested in the readings. Examples are the solar flares of March 1989 and especially of June 1991, which caused a ca. 10% decrease in the cosmic radiation flux reaching the counters. A sinusoidal variation in the cosmic-ray flux with a period of one year is also clearly manifested…
Apparent 14 C Ages of Marine Mollusk Shells from a Greek Island
The excavation of the Cyclope cave, situated on the deserted island of Youra in the Northern Sporades (39°22'N, 24°10'E), revealed material of marine and terrestrial origin in undisturbed layers, suitable for radiocarbon dating. In some cases, material from different reservoirs was found together in the same archaeological layer. This research had two aims. The first was the dating of charcoal-seashell pairs in order to determine the marine reser…

Locating Archaeological Horizons with 14 C Sediment Dating
In 373 bc a catastrophic earthquake and seismic sea wave destroyed Helike, a Greek city near Aigion on the southern shore of the Gulf of Corinth. The ruins were buried by sediments of unknown depth, leaving no trace of the city. We here discuss the radiocarbon dating of organic sediment samples recovered from seven boreholes drilled on the coastal plain in the area where ancient sources located Helike. Most of the samples apparently acquired a su…
