Rhea Silvia
When Amulius learned of the birth he imprisoned Rhea Silvia and ordered a servant to kill the twins. But the servant showed mercy and set them adrift on the river Tiber, which, overflowing, left the infants in a pool by the bank. There, a she-wolf ("lupa"), who had just lost her own cubs, suckled them. Rhea Silvia was herself spared from death due to the intercession of Amulius' daughter Antho. According to Ovid, Rhea Silvia ultimately threw herself into the Tiber.
