Guido Cagnacci (January 19, 1601 – 1663) was an Italian painter of the Baroque period, who produced many works characterized by their use of chiaroscuro and their sensual subjects. He was influenced by the masters of the Bolognese School.
Prior to that he had been in Rome, in contact with Guercino, Guido Reni and Simon Vouet. He may have had an apprenticeship with the elderly Ludovico Carracci. His initial output includes many devotional subjects. But moving to Venice under the name of Guico Baldo Canlassi da Bologna, he renewed a friendship with Nicolas Regnier, and dedicated himself to private salon paintings, often depicting sensuous naked women from thigh upwards, including Lucretia, Cleopatra, and Mary Magdalene. This allies him to a strand of courtly painting, epitomized in Florence by Francesco Furini, Simone Pignoni and others. In 1650, he moved to Venice. In 1658, he traveled to Vienna, where he remained under patronage of the emperor Leopold I.
His life was at times tempestuous, as characterized by his failed elopement (1628) with an aristocratic widow. Some contemporaries remark him as eccentric, unreliable and of doubtful morality. He is said to have enjoyed the company of cross-dressing models.
Cagnacci's work was, in one view, "entirely unappreciated by his contemporaries," but reassessed by modern critics; his painting is "warm with the heightened tones of grazing light, rich in the play of shadows and colors."
