Loveliest of the Gods

Euripides, Orestes 1682-1683 (tr. Edward P. Coleridge):

Go your ways, and honor Peace, fairest of goddesses.

ἴτε νυν καθ᾽ ὁδόν, τὴν καλλίστην
θεῶν Εἰρήνην τιμῶντες.

M.L. West ad loc.:

fairest of deities, Peace: the ancient commentator sees this as a comment on the prolongation of the war (cf. 772 n.). However, Euripides had praised Peace in the same terms before 422 B.C. (Cresphontes fr. 71 Austin); cf. also Supp. 1188 ff. On Peace as a goddess cf. Dodds on Ba. 419-20 and my n. on Hes. Th. 902.
