Federico da Montefeltro
The Portrait of Federico da Montefeltro and His Son Guidobaldo is a painting dating from c. 1475 and housed in the Galleria nazionale delle Marche in Urbino, Italy. There is no consensus on the attribution of the authorship of the painting. The Flemish painter Justus van Gent (whose real name was Joos van Wassenhove) and the Spanish painter Pedro Berruguete are the main contenders for the honour as both painters are believed to have been working in Urbino at the time the painting was made. The painting is part of a series of 28 portrait paintings of 'uomini famosi' (the "Famous men") made for the study of Duke of Urbino Federico da Montefeltro (Musée du Louvre, Paris and Galleria Nazionale, Urbino).
