Almiras: In Mathers' translation of the Clavicula Salomonis, Almiras is described as the “Master of Invisibility.” Together with a number of his infernal ministers, Almiras is invocated in a spell for becoming invisible. He appears in association with the same spell in Mathers' translation of the Sacred Magic of Abramelin the Mage.
