Comment on Aeneid, 1.22:
VOLVERE PARCAS: Either he took the word ‘volvere’ (to turn) from thread, or from a book: for one of them speaks, one of them writes, and another spins the thread. They are called ‘Parcae’ through antiphrasis, because they spare no one. Similarly so, we have lucus (a grove) from non lucendo (not shining) and bellum (war) from nulla re bella (no beautiful thing). The names of the Parcae are Clotho, Lachesis, and Atropos.
VOVLVERE PARCAS aut a filo traxit ‘volvere’ aut a libro; una enim loquitur, altera scribit, alia fila deducit. et dictae sunt parcae κατὰ ἀντίφρασιν, quod nulli parcant, sicut lucus a non lucendo, bellum a nulla re bella. nomina parcarum Clotho Lachesis Atropos.
