“The three young men reached Delphi, and carried out the king’s instructions. That done, Titus and Arruns found themselves unable to resist putting a further question to the oracle. Which of them, they asked, would be the next king of Rome? From the depths of the cavern came the mysterious answer: ‘He who shall be the first to kiss his mother shall hold in Rome supreme authority.’
Titus and Arruns were determined to keep the prophecy absolutely secret, to prevent their other brother, Tarquin, who had been left in Rome, from knowing anything about it. Thus he, at any rate, would be out of the running. For themselves, they drew lots to determine which of them, on their return, should kiss his mother first.
