Romulus and Remus were twin sons of Reia Silvia, daughter of Numitor, king of Alba Longa who had been overthrown by his brother Amulius. To guarantee the throne, Amulius murders Numitor's male descendants and forces his niece Reia Silvia to become Vestal (virgin priestess, consecrated to the goddess Vesta), however, this pregnancy with the god Mars and this union gave rise to the brothers Romulus and Remo (born in March 771 BC)
As punishment, Amulius imprisons Rhea in a dungeon and orders her children to be thrown into the Tiber River. Like a miracle, the basket where the children were ended up getting stuck on one of the banks of the river at the foot of the Palatine and Capitoline mountains, in a region known as the Germalo, where they are found by a wolf who nursed them; next to the children was a woodpecker, a sacred bird for the Latins and for the god Mars (Ares in Greek Mythology), who protects them.
Some time later, a sheepherder named Fáustulo finds the boys near the foot of the Ruminal Fig Tree (Ficus Ruminalis), at the entrance of a cave called Lupercal. He collects them and takes them to his house where they are raised by his wife Aca Larência.
