Overview
Rhea (or Rea) Silvia, also known as Ilia, (as well as other names) was the mythical mother of the twins Romulus and Remus, who founded the city of Rome. This event was portrayed numerous times in Roman art Her story is told in the first book of Ab Urbe Condita Libri of Livy and in Cassius Dio's Roman History. The Legend of Rhea Silvia recounts how she was raped by Mars while she was a Vestal Virgin, resulting in the twins, as mentioned in the Aeneid and the works of Ovid.
Legend
According to Livy's account of the legend, she was the daughter of Numitor, king of Alba Longa, and descended from Aeneas. Numitor's younger brother Amulius seized the throne and killed Numitor's son, then forced Rhea Silvia to become a Vestal Virgin, a priestess of the goddess Vesta. As Vestal Virgins were sworn to celibacy, this would ensure the line of Numitor had no heirs. Rhea, however, became pregnant with the twins Romulus and Remus by the god Mars.
According to Plutarch, she believed this because she saw her children being cared for by a woodpecker 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.
