It is a history book. Jupiter, king of the gods, refrained from an alliance with Thetis, a sea divinity, because he was told her son would be greater than his father. To console her, however, he decreed that all the gods should attend her nuptials with Peleus, King of Thessaly. At this wedding banquet the Goddess of Discord produced a golden apple, inscribed 'To the fairest', which Juno, Minerva, and Venus claimed.
