(săn′bə-nētō)n. pl. san·be·ni·tos
A garment of sackcloth worn at an auto-da-fé of the Spanish Inquisition by condemned heretics, being yellow with red crosses for the penitent and black with painted flames and devils for the impenitent.
[Spanish sambenito, after San Benito, Saint Benedict of Nursia (from its similarity to the scapular supposedly introduced by him).]
