Portrait of two boys, said to be members of the Pesaro family painted by Titian (1485/90 - 1576) with some assistance from his studio, probably in the early 1540s.
This striking work is a rarity in the genre of portraiture for it is one of the first and very few double portraits in Renaissance painting. Its originality also lies in its intensely expressive representation of childhood, rarely seen in Titian’s oeuvre which only comprises a small group of portraits of children. Not until the following century would something comparable be attempted by Rubens when painting his sons (est. £1 - 1.5 million).
