In Persia, the title "the Great" at first seems to be a colloquial version of the Old Persian title "Great King". This title was first used by the conqueror Cyrus II of Persia. The Persian title was inherited by Alexander III of Macedon (336–323 BC) when he conquered the Persian Empire, and the epithet "Great" eventually became personally associated with him. The first reference (in a comedy by Plautus) assumes that everyone knew who "Alexander the Great" was; however, there is no earlier evidence that Alexander III of Macedon was called "the Great". 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 (223–187 BC).
