Astaroth Coin

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

"The Twenty-ninth Spirit is Astaroth.
He is a Mighty, Strong Duke, and appeareth in
the Form of an hurtful Angel riding on an Infernal
Beast like a Dragon, and carrying in his right hand a
Viper. Thou must in no wise let him approach too near
unto thee, lest he do thee damage by his Noisome Breath.
Wherefore the Magician must hold the Magical Ring
near his face, and that will defend him. He giveth true
answers of things Past, Present, and to Come, and can
discover all Secrets. He will declare wittingly how the
Spirits fell, if desired, and the reason of his own fall.
He can make men wonderfully knowing in all Liberal
Sciences. He ruleth 40 Legions of Spirits. His Seal is
this, which wear thou as a Lamen before thee, or else he
will not appear nor yet obey thee, etc"
