Ab urbe condita

It was into this neighbourhood, according to the tradition, that Hercules, after he had killed Geryon, drove his oxen, which were of marvellous beauty. He swam across the Tiber, driving the oxen before him, and wearied with his journey, lay down in a grassy place near the river to rest himself and the oxen, who enjoyed the rich pasture.

When sleep had overtaken him, as he was heavy with food and wine, a shepherd living near, called Cacus, presuming on his strength, and captivated by the beauty of the oxen, determined to secure them. If he drove them before him into the cave, their hoof-marks would have led their owner in his search for them in the same direction, so he dragged the finest of them backwards by their tails into his cave. At the first streak of dawn Hercules awoke, and on surveying his herd and saw that some were missing.
