Ἐπιστάτης

[Meaning] the file man stationed behind [sc. the front-ranker]. The one after him [is] a front-ranker, and the one after him a rear-ranker again -- so that the entire row is made up of front-rankers and rear-rankers. Some call the [sc. first] front-ranker a lochagos ['file-leader']¹ and the [sc. last] rear-ranker an ouragos ['file-closer'],² and those in the middle differently; instead [they call] the one after the front-ranker -- i.e. the second man -- an epistates, and the third from the front-ranker a hypostates.
