 In 1570, El Greco moved to Rome, where he executed a series of works strongly marked by his Venetian apprenticeship.It is unknown how long he remained in Rome, though he may have returned to Venice (c. 1575–76) before he left for Spain.In Rome, on the recommendation of Giulio Clovio, El Greco was received as a guest at the Palazzo Farnese, which Cardinal Alessandro Farnese had made a center of the artistic and intellectual life of the city.
