ἀνταμείβει: “ἀμείβομαι” usu. takes a simple acc. of the person to whom a reply is made (991); but cp. Her. 8.60 “τότε μὲν ἠπίως πρὸς τὸν Κορίνθιον ἀμείψατο”: and, since “ἀποκρίνομαι πρός τινα” was common, it would have been strange if the same construction had been rigidly denied to “ἀμείβομαι”. Even if πρὸς were not taken with “ἀνταμείβει” here, it could still mean “"in relation to"”: cp. Tr. 468 “κακὸν ι πρὸς ἄλλον εἶναι, πρὸς δ᾽ ἔμ᾽ ἀψευδεῖν ἀεί”. So
οἷα causal=“ἐπεὶ τοιαῦτα”: cp. on 263.
