Socrates: (cont.) and then out flows a throng of things such as Gorgons and Pegasuses and multitudes of additional impossibilities (a-mechanos) and of such things giving birth (phuein) to placeless (a-topia) storytellings of monsters (teratologos) . . .

//

καὶ ἐπιρρεῖ δὲ ὄχλος τοιούτων Γοργόνων καὶ Πηγάσων καὶ ἄλλων ἀμηχάνων πλήθη τε καὶ ἀτοπίαι τερατολόγων τινῶν φύσεων

//

Plato coins “teratologos” from teras and logos; teras means a sign, marvel, wonder, divine sign, omen, portent, or monster. So teratologoi are words, accounts, stories, arguments, or reckonings about signs, marvels, wonders, divine signs, oments, portents, or monsters.
