The calyx-krater of Exekias, first published in 1937,1 was discovered at the bottom of a well in the American School excavations on the North slope of the Acropolis in Athens. The circumstances of discovery indicate that someone had carried down the shattered krater from the Acropolis for the express purpose of throwing it into the well, which was then abandoned as a source of water, like several other wells on the North Slope. ... Other wells, containing much pottery, mostly isolated pieces, from the Acropolis were found in the same area.
