Goetia – S. L. MacGregor Mathers (1904) (quoted)

Bathin’s Goetic seal

 
The Eighteenth Spirit is Bathin. He is a Mighty and Strong Duke, and appeareth like a Strong Man with the tail of a Serpent, sitting upon a Pale-Coloured Horse. He knoweth the Virtues of Herbs and Precious Stones, and can transport men suddenly from one country to another. He ruleth over 30 Legions of Spirits. His Seal is this which is to be worn as aforesaid.
