Rhea Silvia
According to Plutarch, she believed this because she saw her children being cared for by a wood pecker and a wolf – animals sacred to Mars. The account says that Rhea Silvia went to a grove sacred to Mars to get water for use in the temple where she encountered Mars who attempted to rape her, she ran into a cave to escape him but to no avail. Mars then promised that her children would be great. These claims of her children's paternity were later doubted by the Roman historian Livy.
