A popular saintly cult soon developed around the figure of Ferdinand, encouraged by the ruling House of Aviz. In January 1444, Peter of Coimbra endowed a fund for a yearly mass to be said in Ferdinand's honor at his chapel in Batalha. Henry the Navigator commissioned a triptych of the life and sufferings of Ferdinand, painted by João Áfonso, to be set up in his own (Henry's) chapel. Some modern authors believe the celebrated Saint Vincent Panels by Nuno Gonçalves were commissioned by Peter of Coimbra as a funerary homage to Ferdinand the Holy Prince.
