The She-wolf, with its evocative power, is the symbol of the city. The sondation of Sixtus IV brought the statue to the Capitoline Hill. Initially, it stood in the fifteenth century facade of the palace. Then, it was transferred inside the palace, on the occasion of Michelangelo's architectural interventions. At that time, the twins were added, attributed to some by Pollaiolo. They transformed the ancient Lateran symbol of justinc into "Mater Romanorum".
