Among Ribera's principal works could be named "Saint Januarius Emerging from the Furnace" in the cathedral of Naples; the "Descent from the Cross" in the Certosa, Naples; the "Adoration of the Shepherds" (a late work; 1650) in the Louvre; the "Martyrdom of Saint Bartholomew" in the Museu Nacional d'Art de Catalunya, Barcelona; and the "Pieta" in the sacristy of San Martino, Naples. His mythologic subjects are often as violent as his martyrdoms: for example, "Apollo and Marsyas", with versions in Brussels and Naples, or the "Tityos" in the Prado. The Prado owns fifty six paintings and other six attributed to Ribera, algonside with eleven drawings, like "Jacob’s Dream" (1639); Louvre contain four of his painting and seven drawings; the National Gallery, London, three; The Real Academia de Bellas Artes de San Fernando owns a nice ensamble of five paintings including "The Assumption of Mary Magdalene" from El Escorial, an early "Ecce Homo" or "The head of St. John the Baptist". He executed several fine male portraits and a self-portrait. "Saint Jerome Writing" in the Prado now has been credited to him by Gianni Papi, a Caravaggio expert. He was an important etcher, the most significant Spanish printmaker before Goya, producing about forty prints, nearly all in the 1620s. The "Martyrdom of Saint Philip (1639; often described as Saint Bartholomew, martyred in similar fashion, but now recognised as St Philip) is in the Prado, Madrid.
