In Roman mythology, Faustulus was the shepherd who found the infant Romulus (the future founder of the city of Rome)[1] and his twin brother Remus along the banks of the Tiber River as they were being suckled by the she-wolf, Lupa.

[4] The Roman historian Livy details the story of the infants Romulus and Remus in his work Ab urbe condita libri (From the Founding of the City).

At the same time, Numitor realized the boy he held in custody was his grandson Remus, and so a plan was hatched to slay King Amulius.

"[5] Greek philosopher, biographer, and essayist Plutarch, addresses Faustulus in his section, The Life of Romulus, in his work Parallel Lives.

Plutarch largely follows Livy's description of Faustulus in his work, From the Founding of the City, while offering some additional information and contending ideas.

Plutarch also claims that Numitor most likely knew of Faustulus and Acca Larentia's raising Romulus and Remus, and "secretly aided the foster-parents in their task.
