οὐ … θέμις, it is not sanctioned by usage, οὐδ᾽ ὅσιον, nor is it pious towards the gods: ius fasque vetant. Cp. Ant. 74 n.: Plat. Phaedop. 108 A “τῶν ὁσίων τε καὶ νομίμων” (meaning rites in honour of the dead): Ar. Th. 676“ὅσια καὶ νόμιμα”.
ἐχθρᾶς ἀπὸ γυναικὸς: for “ἀπό”, ‘on the part of,’ cp. 1469: O.C. 1289 “καὶ ταῦτ᾽ ἀφ᾽ ὑμῶν ... βουλήσομαι” | ..“κυρεῖν ἐμοί”. The prep., emphasising the quarter from which the offerings come, is suitable here.
κτερίσματ̓, used at 931 as including libations (894), but here distinguished from them. See on O. C. 1410“ἀλλ᾽ ἐν τάφοισι θέσθε κἀν κτερίσμασιν”. The verb “κτερίζειν” occurs in Ant. 204(n.).
