Set of heads from ''The Battle of Constantine at the Milvian Bridge'

A set of six prints reproducing heads of figures depicted in the fresco of 'The Battle of Constantine at the Milvian Bridge', designed by Raphael and eventually painted by his workshop in the Sala di Costantino in the Vatican between 1520 and 1524. All prints are lettered along the lower margin and numbered at top right. Probably from "Tetes choisies de personagges illustres..." published by Fidanza in Rome in 1785. 

Paolo Fidanza became famous for publishing six volumes of prints of heads after Raphael between 1757 and 1763.
