[144] ἄστυ seems here used in its primitive sense dwelling, home (vas = to dwell); while πόλις is the citadel, “πόλις ἄκρη”. But there is no clearly marked distinction, cf. Od. 6.177, Od. 8.525. In Od. 14.472-73 “πόλις ἄστυ” and “τεῖχος” go together. σαώξηις, not “σαώσεις”, in spite of Ar., see H. G. § 326. 4.
