“ Mercury was angry with Pelops for throwing his son Myrtilus into the sea and depriving him of his life by law; he sought vengeance in order to make up for the death. 2. So he incited Pelops' sons, Atreus and Thyestes, to such discord that they smashed the bond of kinship. 3. So, when they were ruling the kingdom in turns, since Thyestes knew that the kingdom was fated to remain in the hands of the one who had the ram with the golden fleece (which Atreus had been in possession of since he had received the kingdom) , he seduced Europa, his brother's wife, in the hope of getting it for himself. ”
