According to the roman mythology, the founders of Rome were Romulus and Remus. The twin-brothers were the supposed sons of the god Mars and the priestess Rhea Silvia. The story begins with the deposition of Numitor (their grandfather and king of the ancient Italian city of Alba Longa), by his brother Amulius. Numitor's daughter, Rhea Silvia, was made a Vestal Virgin by Amulius - which meant that she was made a priestess of the godess Vesta and therefore forbidden to marry. However, the god Mars came to her in her temple and of him she conceived her two sons, Romulus and Remus.
