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.
