[1] The headword pla/th is not recognised by LSJ s.v. in this sense, for which see already under pi 1702.
[2] Quotation (and context) unidentifiable, though it contains strange echoes of Thucydides 7.25.6, on a tactic of the Athenians in the Great Harbour at Syracuse in 413: "they deployed against [the stakes] a ten-thousand-capacity ship which had wooden towers and paraphragmata" (web address 1). On such towers see generally Lionel Casson, Ships and Seamanship in the Ancient World (Baltimore 1992) 122 n.92; and 172 n.25 there on 'ten-thousand-capacity' merchant vessels. Simon Hornblower in his Commentary (III 585) claims that the unit implicit in murioforos is usually assumed to be talents, but his predecessor Gomme had cited H.T. Wallinga for the greater probability of medimnoi (of dry goods) or amphorae (of liquids); and see also Casson loc.cit.
