In mythology, Romulus and Remus were brought up by which animal?

Romulus and Remus are the legendary founders of Rome. Traditionally, they were the sons of Rhea Silvia, daughter of Numitor, king of Alba Longa.

Numitor had been deposed by his younger brother Amulius, who forced Rhea to become one of the Vestal Virgins in order to prevent her from giving birth to potential claimants to the throne. Nevertheless, Rhea bore the twins Romulus and Remus, fathered by the war god Mars.

Amulius ordered the infants drowned in the Tiber River, but the trough in which they were placed floated down the river and came to rest at the site of the future Rome. There a she-wolf and a woodpecker—both sacred to Mars—suckled and fed them until they were found by the herdsman Faustulus.

Reared by Faustulus and his wife, Acca Larentia, the twins became leaders of a band of adventurous youths, eventually killing Amulius and restoring their grandfather to the throne. They subsequently founded a town on the site where they had been saved. When Romulus built a city wall, Remus jumped over it and was killed by his brother.
