Shax Medallion

This is a seal from the book "Lesser Key of Solomon".  According this text, the spirit Shax, is described thus

"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, A, 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"
