Two burials under a Chios basilica reveal how sacred space and identity were built.

This study re-examines two ancient burials found beneath the mosaic floor of St. Isidore Cathedral on Chios, Greece. The tomb's unusual construction and lack of grave goods made dating difficult. Tradition links the site to martyrs Isidore and Merope, and Byzantines built grand churches there in their honor. The authors combine archaeology, history, and archaeogenetics to explore how this sacred place shaped local identity over time.

Sample interpretation

No ancient DNA samples or Y-chromosome data are reported in this paper. The study focuses on archaeological context, historiography, and the potential of archaeogenetics, but no genetic results or sample statistics are provided. Therefore, no genetic ancestry or haplogroup conclusions can be drawn from this abstract.

For genealogy enthusiasts

For ancestry enthusiasts, this paper highlights how archaeology and genetics can together study sacred sites and identity. However, without actual DNA data, it offers no direct clues about ancient lineages or migrations. It reminds us to separate historical tradition from genetic evidence.

Abstract

This article aims to present a comprehensive evaluation of two human burials unearthed during rescue excavations conducted in 1981/82 beneath the mosaic floor of the central nave of the Basilica of Saint Isidore, in the Letsaina area of the capital of Chios Island. The archaeological site of this Byzantine monument, characterized by architecturally complex stratigraphic sequences spanning different periods and adorned with elaborate mosaics reflecting its former grandeur, provided a multidimensional framework for the investigation. Whereas archaeological investigations were conducted prior to the site’s recent and important restoration project, the archaeological interpretation presented herein reflects the stratigraphic framework and understandings established during the 1980s excavations. The specific construction and placement of the tomb, along with the absence of grave goods, posed significant challenges for its dating. Additionally, an intriguing aspect of their discovery was its evocation—according to tradition—with the burial of the martyrs Isidore and Merope in this sacred space, where the Byzantines erected monumental Christian structures in their honor.
