Suetonius includes a long one about a tomb being found in Capua which warned that the grave being moved would result in ‘a son of Troy slain by his kin and avenged at heavy cost to Italy’, which is a pretty suspiciously detailed prophecy. Caesar, of course, liked to tell everyone that he was descended from the goddess Venus, while the Romans believed themselves to be descended from Aeneas, who escaped the sack of Troy.
