Claros had been entirely buried in the alluvial silt deposited by the small river at the site, a widespread phenomenon along this coastline during the 1st century BC, as the hinterland was deforested. T. Macridy uncovered the monumental entrance to the sanctuary in 1905 and returned for further explorations with the French archaeologist Charles Picard in 1913. Excavations recommenced between 1950 and 1961 under Louis Robert, and a series of important Roman dedicated monuments came to light, as well as the famous
Doric Temple of Apollo, seat of the oracle, in its final grand though uncompleted Hellenistic phase, 3rd century BC. The Sacred Way was excavated in 1988 under J. de La Genière. Since then much alluvial spoil has been carted off-site and Claros was prepared to receive visitors. After the beginning of the Roman Province of Asia (end of the 2nd century BC), prominent citizens of Colophon helped to increase the authority of the sanctuary, the importance of the religious competitions and the fame of the oracle. To celebrate the major sacrifices before crowds consisting of Greeks and non-Greeks, four rows of iron rings attached to heavy blocks allowed a hundred victims to be killed simultaneously. Claros is the only sanctuary in the Greek world which offers a clear picture of the way priests could perform the
hecatomb. ==References==
