Note 21 — Chapter LXII · TWENTY-FIRST YEAR OF THE WAR. — OLIGARCHY OF FOUR HUNDRED AT ATHENS.
Reading edition
Thucyd. viii, 61. ἔτυχον δὲ ἔτι ἐν Ῥόδῳ ὄντος Ἀστυόχου ἐκ τῆς Μιλήτου Λέοντά τε ἄνδρα Σπαρτιάτην, ὃς Ἀντισθένει ἐπιβάτης ξυνέπλει, τοῦτον κεκομισμένοι μετὰ τὸν Πεδαρίτου θάνατον ἄρχοντα, etc.
I do not see why the word ἐπιβάτης should not be construed here, as elsewhere, in its ordinary sense of miles classiarius. The commentators, see the notes of Dr. Arnold, Poppo, and Göller start difficulties which seem to me of little importance; and they imagine divers new meanings, for none of which any authority is produced. We ought not to wonder that a common miles classiarius, or marine, being a Spartan citizen, should be appointed commander at Chios, when, a few chapters afterwards, we find Thrasybulus at Samos promoted, from being a common hoplite in the ranks, to be one of the Athenian generals (viii. 73).
The like remark may be made on the passage cited from Xenophon (Hellenic. i. 3, 17), about Hegesandridas—ἐπιβάτης ὢν Μινδάρου, where also the commentators reject the common meaning (see Schneider’s note in the Addenda to his edition of 1791, p. 97). The participle ὢν in that passage must be considered as an inaccurate substitute for γεγενημένος, since Mindarus was dead at the time. Hegesandridas had been among the epibatæ of Mindarus, and was now in command of a squadron on the coast of Thrace.
