Aratron
Aratron: A demon named in the Mathers translation of the Grimoire of Armadel. Aratron is said to reveal knowledge of the soul. He also possesses details abut the rebellion of the angels and the subsequent War in Heaven. There is a warning in the Grimoire of Armadel suggesting that it is unwise to spend too much time with any of this demon's familiar spirits. The name of this demon also appears in Rudd's Treatise on Angel Magic. Here, he is an Olympic spirit connected with Saturn. The name Aratron may be a variation on the demon Ariton.
