Andrea di Michele di Francesco de' Cioni (c. 1453 - 1488), later known as Andrea del Verrocchio, was an Italian sculptor, goldsmith, and painter, who worked at the court of Lorenzo de' Medici in Florence. One of his pupils was Leonardo da Vinci.
In 1476, Uberto Alberti, accompanied by Lorenzo de' Medici, attended the unveiling of Verrocchio's latest work in the Santa Croce cloister. However, this exposition was intruded upon by Ezio Auditore, who killed Uberto for the betrayal of his family.
