Note 104 — ARRIAN ON COURSING.
William Dansey translation
The king of Persia was called μέγας βασιλεὺς, according to Suidas, διὰ τὸ πλείονι δυνάμει χρῆσθαι τῇ Περσικῇ· τοῖς δὲ ἄλλοις προσετίθεσαν καὶ τῶν ἀρχομένων ὀνόματα, οἷον Λακεδαιμονίων, Μακεδόνων. The title still exists in “Le Grand Seigneur.”
