Details of Poussin's artistic training are somewhat obscure. Around 1612 he traveled to Paris, where he studied under minor masters and completed his earliest surviving works. His enthusiasm for the Italian works he saw in the royal collections in Paris motivated him to travel to Rome in 1624, where he studied the works of Renaissance and Baroque painters—especially Raphael, who had a powerful influence on his style. He befriended a number of artists who shared his classicizing tendencies, and met important patrons, such as Cardinal Francesco Barberini and the antiquarian Cassiano dal Pozzo. The commissions Poussin received for modestly scaled paintings of religious, mythological, and historical subjects allowed him to develop his individual style in works such as "The Death of Germanicus", "The Massacre of the Innocents", and the first of his two series of the "Seven Sacraments".
