Simone de Magistris (known from 1555–1613) was an Italian painter and sculptor.
Born at Caldarola, Marche, he was the son of Giovanni Andrea de Magistris and Camilla di Ambrogio, and brother to Palmino and to Giovanfrancesco, both painters. After leaving the family workshop, he moved to Loreto, where he studied for a while under the aged Lorenzo Lotto.
He is considered "one of the first exponents of the Mannerist style" in paintings.[1]
De Magistris worked for a long time under cardinal Evangelista Pallotta, who largely contributed to the renovation of Caldarola.
