Inferno in colours: Malphas the demon, from Collin de Plancy's Dictionnaire Infernal

From an original 1863 Louis le Breton's illustration The demon Malphas (Malpas) is a Fallen Angel and 39th of the 72 Spirits of Solomon. A powerful president in Hell, he appears first as a crow and then, when commanded, as a human who speaks in a hoarse voice. He skillfully builds houses and high towers and brings down the temples and towers of enemies. He will bring deceivers together quickly. Malphas commands 40 legions of Demons. He destroys the desires, thoughts, and accomplishments of anyone’s enemies. Malphas gives good Familiars. He will receive a sacrifice kindly but then deceive the one who offers it.
