ταρ᾽ Ἀλφεῷ: παρά in prose, with genitive or dative, is shrivelled into an exclusively personal preposition, like Fr. chez. It is freer and more original in Pindar, although “in the domain of Alpheios” would err only in suggesting too much.
δέμας: The living body, originally distinct from σῶμα. Used plastically as the Lat. corpus = se.
