Barbatos is a Fallen Angel and eighth of the 72 Spirits of Solomon. Formerly a member of the Angelic Order of Virtues, Barbatos is a great count, earl, and duke of Hell, where he rules 30 Legions of Demons. When the Sun is in Sagittarius, he appears with four kings and three companies of troops. He understands the languages of all animals, especially the singing of birds, the barking of dogs, and the lowing of bullocks. Barbatos can reveal treasures hidden by magic and can reconcile friends and people in power. He teaches all sciences and knows all things in the past and of the future.
From “The Goetia: The Lesser Key of Solomon the King” (1904) Written by S.L. MacGregor Mathers

He brealieth the Hidden Treasures open that have been laid by the Enchantments of Magicians.

He ruleth over 30 Legions of Spirits. His Seal of Obedience is this, the which wear before thee aforesaid.
From the “Pseudomonarchia Daemonum” ( 1583 ) Written by Johann Weyer (Johann Wier)
Barbatos, a great countie or earle, and also a duke, he appeareth in Signo sagittarii sylvestris,1 with foure kings, which bring companies and great troopes. He understandeth the singing of birds, the barking of dogs, the lowings of bullocks, and the voice of all living creatures. He detecteth treasures hidden by magicians and inchanters, and is of the order of vertues, which in part beare rule: he knoweth all things past, and to come, and reconcileth freends and powers; and governeth thirtie legions of divels by his authoritie.
Original Text : Barbatos magnus Comes & Dux, apparet in signo Sagittarii silvestris cum quatuor regibus tubas ferentibus. Intelligit cantus avium, canum latratus, mugitus boum & cunctorum animalium: thesauros item à magis & incantatoribus reconditos, detegit: Et est ex ordine Virtutum, partim Dominationum. Triginta præsidet legionibus. Novit præterita & futura: tam amicorum quam inimicorum animos conciliat.
From the “Dictionnaire Infernal” (edition of 1863 ) Written by Jacques Auguste Simon Collin de Plancy
Original Text :Barbatos, grand et puissant démon, comte-duc aux enfers, type de Robin des Bois ; il se montre sous la figure d’un archer ou d’un chasseur ; on le rencontre dans les forêts. Quatre rois sonnent du cor devant lui. Il apprend à deviner par le chant des oiseaux, le mugissement des taureaux, les aboiements des chiens et les cris des divers animaux. Il connaît les trésors enfouis par les magiciens. Il réconcilie les amis brouillés. Ce démon, qui était autrefois de l’ordre des vertus des cieux ou de celui des dominations, est réduit aujourd’hui à commander trente légions infernales. Il connaît le passé et le futur .
