ἀστράπτω [page 87]
The MGr ἀστράφτει , it lightens, reinforces the literary record. The word was vernacular, though, as in the case of the noun, we know of no exx. except in the magic papyri, P Lond 46 .150 (iv/A.D.) (= I. p. 70) ἐγώ εἰμι ὁ ἀστράπτων : so ib. 121 .234 (iii/A.D.) and 122 .92 (iv/A.D.) (= I. pp. 92, 119).
