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 ... They were put inside the vase to be added at some future time and have now been inserted. ... The man in front of him has thrown his arm back, raising the spear to the height of his head, in readiness to hurl or thrust at his opponent. ... 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.
