Oil on canvas, 23cm by 65.5cm.
The artist, who was both a painter and an architect, was known as il Bolognese from his place of birth.
He was a pupil of the Carracci family of artists, to whom he was related, painting both portraits and landscapes in their studio.
Later, in Rome, he was appointed architect to Pope Paul V and was also patronised by later Popes.
He spent two years in France working for both Cardinal Mazarin and Louis XIV, chiefly as an architect, but he also painted frescoes in the Louvre.
