Dughet was trained by
Poussin, who later became his brother-in-law and whose name he adopted. Following
Claude and Poussin, Dughet became one of the best known landscape painters of 17th-century Rome. His style was influenced by the work of
Rosa.
His early biographers emphasised his precocity and the speed of his execution.The figures in some of his works, including his
'Landscape with the Union of Dido and Aeneas', are by other painters.
Dughet was in demand for landscape
frescoes as well as for his paintings in oil. His style changed little throughout his life, so his paintings are not easily datable.
