Goetia - S. L. MacGregor Mathers (1904)
The Forty-fourth Spirit is Shax, or Shaz (or Shass). He is a Great
Marquis and appeareth in the Form of a Stock-Dove, speaking with a
voice hoarse, but yet subtle. His Office is to take away the
Sight, Hearing, or Understanding of any Man or Woman at the
command of the Exorcist; and to steal money out of the houses of
Kings, and to carry it again in 1,200 years. If commanded he will
fetch Horses at the request of the Exorcist, or any other thing.
But he must first be commanded into a Triangle, Ò, or else he
will deceive him, and tell him many Lies. He can discover all
things that are Hidden, and not kept by Wicked Spirits. He giveth
good Familiars, sometimes. He governeth 30 Legions of Spirits, and
his Seal is this, etc.
Pseudomonarchia daemonum - Johann Wier (1583)
Shax, alias Scox, is a darke and a great marquesse, like unto a
storke, with a hoarse and subtill voice: he dooth marvellouslie
take awaie the sight, hearing and understanding of anie man, at
the commandement of the conjuror: he taketh awaie monie out of
everie kings house, and carrieth it backe after 1200. yeares, if
he be commanded, he is a horssestealer, he is thought to be
faithfull in all commandements: and although he promise to be
obedient to the conjuror in all things; yet is he not so, he is a
lier, except he be brought into a triangle, and there he speaketh
divinelie, and telleth of things which are hidden, and not kept of
wicked spirits, he promiseth good familiars, which are accepted if
they be not deceivers, he hath thirtie legions.
Dictionnaire Infernal - Collin de Plancy (1863)
As duke and high marquis of hell, Scox/Chax commands 30 legions.
He appears as a stork with a raucous voice, and is known to be
deceitful. He steals horses, and takes the silver in the houses he
possesses only to return it 1200 years later if everything is still
in order. If he is confined to a triangle, he will speak truth on
supernatural matters, point out hidden treasures not guarded by evil
spirits, and obey the exorcist. If he is not confined, he will lie
and not always obey the exorcist.
