In Persia, the title “the Great” at first seems to have been a colloquial version of the Old Persian title “Great King”. It was first used by Cyrus II of Persia. The title was inherited by Alexander III when he conquered the Persian Empire, and the epithet eventually became personally associated with him. The first reference to this is in a comedy by Plautus, in which it is assumed that everyone knew who “Alexander the Great” was; however, there is no evidence that he was called “the Great” before this. The early Seleucid kings, who succeeded Alexander in Persia, used “Great King” in local documents, but the title was most notably used for Antiochus the Great. Once the term gained currency, it was broadened to include persons in other fields, such as the philosopher Albert the Great.
