Luis González Obregon describes the three basic types of tunics used to distinguish those being punished by the Inquisition. These were the "Samarra", "Fuego revolto", and the "Sambenito". The "Samarra" was painted with dragons, devils, and flames amongst which the image of the prisoner could be distinguished, signifying that the impenitent heretic was condemned to be burnt alive at the stake. The "Fuego revolto" was painted simply with flames pointing downwards, signifying that the heretic who became penitent after being condemned was not to be burnt alive at the stake, but was to have the mercy of being strangled before the fire was lit. Finally the "Sambenito" featured red saltires, whose wearer was only to do penance. Eventually all three types of tunics became known as "sambenito"; a conical cap, denominated "coroza" (and "capirote"), of the same material and motifs as the corresponding "sambenito", would also be worn.
