Agaras is described in grimoires such as the Livre des Esperitz (as Agarat), the Pseudomonarchia Daemonum, the Lesser Key of Solomon, and the Dictionnaire Infernal as a duke "under the power of the east," an "old man, riding upon a crocodile, and carrying a hawk on his fist,"[1][note 1] who teaches languages, stops and retrieves runaway persons, causes earthquakes, and grants noble titles.
Lemegeton Clavicula Salomonis and the Pseudomonarchia Daemonum both list him as the second spirit, and state that he commands 31 legions of demons, while the Livre des Esperitz (which describes him simply as an old man) gives him 36.
[2][1][3][4][5] The Book of the Office of Spirits places him (as Agaros) second under Oriens and describes him as an old man riding a cockatrice, without the hawk.
[12] Agares possesses a young nun named Sister Adelina Marinescu (played by Ada Lupa) in the 2017 film, The Crucifixion, directed by Xavier Gens.
Agares is portrayed under the same name as a sleepy young man in Japanese anime and manga series Welcome to Demon School!
