Barbatos' seal
In demonology, Barbatos is an Earl and Duke of Jinnestan, ruling thirty legions of demons and has four kings as his companions to command his legions. He gives the understanding of the voices of the animals, says past and future, conciliates friends and rulers, and he can lead men to hidden treasures that have been hid by the enchantment of magicians.
His name seems to derive from Latin 'barbatus', bearded, old man, philosopher.
He is the 8th demon in The Lesser Key of Solomon, while Pseudomonarchia Daemonum listed him as the 6th demon. He is also mentioned in Grand Grimoire as subordinate of Satanachia.
