Broneer, O ... American School of Classical Studies at Athens ... 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 ... 1956 ... 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. ... An incised line, drawn by compass, sets off the rim. The white color is well preserved, in contrast to the white on the fragments found in the well, which had largely disappeared from being immersed in the water (cf. breastplate of Diomedes on the left flank, Pl. 50 a). ... Since my first article on the North Slope krater was published, some important literature has appeared dealing with the art of Exekias and with the relation of the krater to the rest of his works.6 All have accepted the attribution to Exekias and the chronological order I proposed, placing the krater near the end of Exekias'career.
