For Plataia see already pi 1700. In the present entry the primary headword 'Plataian' more precisely means 'man of Plataia', with its plural as given at the end.
In between them, the phrase *Plataie/a nau=s -- presumably quoted from somewhere but attested only here -- is problematic. First, the transmitted adjective *Plataie/a appears to be masculine accusative; emendations have been proposed to make it feminine nominative, i.e. *Plataiai/a (Aemilius Portus) or *Plateai/a (Bernhardy); and their result would be the phrase 'Plataian ship'. But why would a small landlocked polis have such a ship? Rather, classical Plataia enjoyed a degree of fame for its temples, especially those of Hera and Athens; so perhaps [DW] this entry's transmitted noun ought to be an accusative of nao/s 'temple'.
