Purson is a Great King of Hell, being served and obeyed by twenty-two legions of demons. He knows of hidden things, can find treasures, and tells past, present and future. Taking a human or aerial body he answers truly of all secret and divine things of Earth and the creation of the world. He also brings good familiars.
Purson is depicted as a man with the face of a lion, carrying a ferocious viper in his hand, and riding a bear. Before him there can be heard many trumpets sounding.
