Assyrian Identity in Ancient Times and TodayWhen the territories west of the Euphrates were conquered...Aramaic became the second language of the empire, alongside Akkadian. Assyrian reliefs beginning from the time of Tiglath-pileser III provide numerous portrayals of a scribe writing on a tablet or a board, side by side with another scribe writing on papyrus or a parchment scroll. Th[e] pictorial rendition undoubtedly corresponds to the phrases "Assyrian scribe" (tupsharru Ashuraya) and "Aramaic scribe" (tupsharru Aramaya) that occur together in the various documents, referring to officials in the imperial service.

Thucydides reports that the Persian Artaphernes, who was carrying a message from the Great King to Sparta, was taken prisoner, brought to Athens, and the letters he was carrying were translated from the Assyrian language.
Thucydides 4.50.2:
He was conducted to Athens, where the Athenians got his dispatches translated from the Assyrian character (Assuri?n grammat?n) and read them.
