Adam Clarke on Jeremiah 51:27

Set ye up a standard - Another summons to the Medes and Persians to attack Babylon.

Ararat, Minni - The Greater and Lesser Armenia.

And Ashchenaz - A part of Phrygia, near the Hellespont. So Bochart, Phaleg, lib. 1 c. 3, lib. 3 c. 9. Concerning Ashchenaz Homer seems to speak, Il. 2:370, 371: - Φορκυς αυ Φρυγας ηγε, και Ασκανιος θεοειδης, Τηλ' εξ Ασκανιης. "Ascanius, godlike youth, and Phorcys led

The Phrygians from Ascania's distant land."

Calmet thinks that the Ascantes, who dwelt in the vicinity of the Tanais, are meant.
