No biographical information exists for an author of the Artaxerxes Letters. The work is attributed to the Persian king Artaxerxes and belongs to a genre of Greek literary forgeries, where letters were pseudonymously composed in the names of foreign rulers for rhetorical or historical purposes.

The Artaxerxes Letters is a collection of epistles presumed lost or fragmentary.

Letters attributed to Artaxerxes I or II appear within extant historical narratives, such as the works of Xenophon and the biblical books of Ezra and Nehemiah, serving as literary devices to authenticate accounts or illustrate royal authority. A standalone collection would fit within the broader Hellenistic tradition of pseudepigraphal letter-writing.
