οὐ γὰρ δὴ σύ γ̓: (How can you be coming from Troy?),—for you certainly did not go there with us at first. For this use of “οὐ γὰρ δή...γε” in rejecting an alternative supposition, see O. C. 110 n.—The order of the words almost compels us to join κατ᾽ ἀρχὴν τοῦ … στόλου: cp. Legg. 664 E “κατ᾽ ἀρχὰς τῶν λόγων”. Then “ἦσθα ναυβάτης” (cp. 1027) “ἡμῖν” (dat. of interest)=‘sailedst in our fleet.’ But it would also be possible to join “ναυβάτης” with “τοῦ στόλου” (partitive gen., cp. 73), taking “κατ᾽ ἀρχήν” as=‘originally.’
