In the article Darius and His Behistun Inscription, which appeared in AJSL, LV (1938), 392 ff., Professor Olmstead on page 398 arrives at the conclusion that the Magian GaumAta, who claimed to be Bardia, son of Cyrus,' ruled not seven months but one and seven months, namely, from March 11, 522, to October 17, 521. As a consequence he places Darius' aiccession to the throne not on Teiritu 10, 522/21, but on Tesritu 10, 521/20, a dating which if proved correct would make it necessary to drop all dates given in my table for the events of the and second years of Darius' reign (AJSL, LV, 14347) by one year. Professor Olmstead bases his conclusion on the wellknown fact that a number of Babylonian tablets are dated in the second, third, and fourth months of the accession year of Barzia,2 while others are dated in the and the third to eighth months of the first year of Barzia.
