レーザー計測でエーゲ海諸島の古代遺跡を発見(Archaeologists use lasers to locate ancient settlements and artefacts on Greek Islands)

古代遺跡の調査において、University of Copenhagen(コペンハーゲン大学)などの国際研究チームは、ギリシャのCyclades(キクラデス諸島)にある、多数の無人島を対象に、従来の発掘ではなく、レーザー測量(LiDAR)や地磁気測定(マグネトメトリー)といった非破壊・非侵襲の最新技術を駆使した網羅調査を実施した。これにより、藪や樹木に覆われていた地形の凹凸や、埋もれていた構造物の痕跡を空中/地上から浮かび上がらせ、石壁や建造物跡、古代から中世、近代まで多時代にわたる人類の活動痕を見いだしている。調査対象には先史時代(新石器時代)、青銅器時代、古典期、中世、更には近世に至るまでの遺構・遺物が含まれ、これまで人の居住や利用が想定されてこなかった無人島も含まれる。こうした手法により、今後の発掘は「どこを掘るか」をより的確に定められるようになり、過剰な発掘を避けつつ、遺産の保護と持続可能な文化遺産管理、さらには観光開発とのバランスを図ることが期待される。本研究は、キクラデス諸島の歴史観を根本から広げ、島々における人の利用と移動のあり方を再考させるものとなっている。

Abstract

Quarries are information-rich anthropic landscapes, but their unique characteristics often limit the effectiveness of traditional archaeological documentation strategies. Here, the authors present a novel interdisciplinary method for the documentation and analysis of these landscapes, focusing on two ancient marble quarries on the Mediterranean island of Naxos. The workflow, combining lidar, photogrammetry, sculptural and architectural study, geoscience, ecological study and archaeological survey, provides a means for the systematic documentation of quarry landscapes in the Mediterranean and beyond, and aims to promote an understanding of premodern extractive activities not as isolated occurrences but as important aspects of interconnected, evolving landscapes.

Highlights

  • Geophysical prospection is rarely used on Cycladic islands or ancient Greek rural contexts.
  • Magnetometry applied for the first time on the island of Paros.
  • Possible subsurface features identified around a Hellenistic tower site.
  • Demonstrates a mixed-methods approach crucial to documenting cultural heritage landscapes under threat.

Abstract

Geophysical prospection in Greece has predominantly been applied at ancient urban sites on the mainland and Crete. It is rarely used on Cycladic islands and even less so in rural contexts, despite their centrality to the eastern Mediterranean region and the ability of geophysical techniques to efficiently cover extensive rural spaces and identify archaeological traces of agriculture and landscape exploitation. This study applies magnetometry for the first time on Paros, around the so-called Hellenistic Palaiopyrgos tower, with the aim of detecting the presence of buried ancillary structures and archaeological indications of agricultural activity. Several sub-surface features were identified and are compared to those at similar tower sites in the Cyclades and Greece. We highlight challenges to this approach and possible pathways forward specific to the investigation of rural landscapes. The data captured in this study will also play a central role in the protection of the Palaiopyrgos archaeological site, highlighting a methodological approach to be deployed in other areas that are experiencing rising pressure due to tourism and rapidly expanding development.
