Janelas Verdes, and the Museu Nacional de Arte Contemporânea" ("National Museum of Contemporary Art") at the old location of the Academia's Galeria at São Francisco da Cidade (since renamed the Chiado Museum). The latter collection's cut-off date was roughly 1850, everything prior to that assigned to Arte Antiga. The MNAA's first museum director was the energetic José de Figueiredo, who promptly began reforming the museum based on the latest planning and exhibition principles and re-orienting it decisively towards painting. Figueiredo was the first to study and identify the authorship and significance of Saint Vincent Panels, a 15th-century polyptych discovered c. 1882 and attributed by Figueiredo to Nuno Gonçalves. The St. Vincent panels were installed in the museum by 1916 and remain perhaps its best known piece. In 1940, the MNAA expanded its installations by acquiring the neighboring old convent of Santo Alberto and turned it into an annex connected by a footbridge. The chapel of the convent, a fine example of 18th Portuguese Baroque art and architecture, was incorporated into the exhibits. Collection The collection includes painting, sculpture, metalwork, textiles, furniture, drawings, and other decorative art forms from the Middle Ages to the early 19th century. The collections, especially those for the 15th and 16th centuries, are particularly important regarding the history of Portuguese painting, sculpture, and metalwork. Painting European The European painting section of the museum is significant and is represented by Jacob Adriaensz Backer, Bartolomé Bermejo, Triptych of the Temptation of St. Anthony by Hieronymus Bosch, Pieter Brueghel the Younger, David Gerard, Saint Jerome in His Study by Albrecht Dürer, Lucas Cranach, Piero della Francesca, Jan Gossaert, Hans Holbein the Elder, Pieter de Hooch, Adriaen Isenbrandt, Quentin Metsys, Hans Memling, Antonis Mor, Joachim Patinir, Jan Provost, Raphael, José Ribera, Andrea del Sarto, David Teniers the Younger, Tintoretto, Anthony van Dyck, Diego Velázquez, David Vinckeboons, Hendrick Cornelisz Vroom, Francisco de Zurbarán, François Boucher, Nicolas Poussin and others. Portuguese Perhaps the most famous work in the museum is the Saint Vincent Panels, which date from before 1470 and are attributed to Nuno Gonçalves, court painter of King Afonso V. Though the history of the polyptych remains enshrouded in mystery, the six large panels have been argued to portray people from all levels of late medieval Portuguese society venerating Saint Vincent, in what would be one of the first group portraits in European art. There are 60 figures on the panels.
