Which Spanish artists did Pablo Picasso study at the Prado Museum?

During his time in Madrid in 1897, Pablo Picasso frequently visited the Prado Museum to study the works of Spanish masters. He specifically noted his admiration for Diego Velázquez, whom he considered first-class, and El Greco, whose work he found magnificent.1

Additionally, Picasso studied and copied the works of Francisco Goya at the museum in 1898, including a portrait of the bullfighter Pepe Illo and a drawing for one of the Caprichos titled Bien tirada está. While he also observed the paintings of Bartolomé Esteban Murillo during these visits, he noted that he was not convinced by all of the artist's works.1
