Charles Ellicott Commentary Ezra 6:2

"And there was found at Achmetha, in the palace that is in the province of Media, a roll, and therein was thus written for a record:" — Ezra 6:2 (ASV)

At Achmetha. —That is, Ecbatana, the Median capital of Cyrus. It is probable that the original roll of parchment had been destroyed at Babylon by Smerdis, but a copy of it was found here, probably in a Chaldean transcript.
