Maratta was born in Camerano. He was about in Rome from 1636-45 and trained under Andrea Sacchi. In 1650 he was in Rome again, and after the deaths of Sacchi and Pietro da Cortona he was the leading painter there. He died in Rome. He produced portraits and mythological paintings, but was chiefly famous for his religious pictures.
He is thought to have painted the figures in Dughet's 'Landscape with Dido and Aeneas' in this Collection. He is sometimes called Maratti.
