Abydenus was a
Greek historian, and the author of a
History of the Chaldeans and Assyrians, of which some fragments are preserved by
Eusebius in his
Praeparatio Evangelica, and by
Cyril of Alexandria in his work against
Julian. Several other fragments are preserved by
Syncellus. These were particularly valuable for chronology. An important fragment, which clears up some difficulties in Assyrian history, has been discovered in the Armenian translation of the
Chronicon of Eusebius.
