δ1491Δραγμὴ χαλαζῶσα
a drachma falling as hail; a handful falling as hail
In the time of Diophantus the theor{et}ikon came into being, a drachma. And when a hailstorm from the sky stopped at that time, the joke was that it was a handful of hailstones.
Δραγμὴ χαλαζῶσα· ἐπὶ Διοφάντου τὸ θεωρητικὸν ἐγένετο δραγμή. ἐπεὶ δὲ ἐπέσχε χάλαζα τότε ἀπὸ τοῦ ἀέρος, δραγμὴν αὐτὴν χαλαζῶν ἐπέσκωπτον.
