Somatophylakes (Greek: Σωματοφύλακες; singular: somatophylax, σωματοφύλαξ) were the bodyguards of high-ranking people in ancient Greece.
Coin of Balacrus, somatophylax of Alexander the Great, as satrapofCilicia, with letter "B" next to the shield, standing for B[AΛAKPOI].[1] Tarsos. 333–323 BC.
(Note that this list is speculative in several cases and would be disputed by scholars. For example, Hephaestion was probably not named as early as given below. The only complete list of Alexander's bodyguard in the original sources is found in Arrian (6.28.4), upon the extraordinary appointment of Peucestas in Carmania.)
