Liber Memorialis: The Number and Origins of the Jupiters

Quot ferunt vel esse Iovis vel ubi; in loco deos deasque:
Ioves fuere tres: primus in Arcadia Aetheris filius, cui etiam Aetherius cognomen fuit; hic primum Solem procreavit. Secundus ibidem in Arcadia qui Saturnius cognominatur; qui ex Proserpina Liberum patrem procreavit vini inventorem. Tertius Cretae Saturni et Opis filius, Optimus Maximus qui est appellatus.

There were three Jupiters: the first in Arcadia, the son of Aether, whose cognomen was Aetherius; this one first created the son. The second likewise in Arcadia who was cognomened Saturnius; who begat from Proserpina Liber Pater the inventor of wine. The third, on Crete, the son of Saturn and Ops, is called Optimus Maximus.
