Goetia - S. L. MacGregor Mathers (1904)
The Forty-second Spirit is Vepar, or Vephar. He is a Duke Great
and Strong and appeareth like a Mermaid. His office is to govern
the Waters, and to guide Ships laden with Arms, Armour, and
Ammunition, etc., thereon. And at the request of the Exorcist he
can cause the seas to be right stormy and to appear full of ships.
Also he maketh men to die in Three Days by Putrefying Wounds or
Sores, and causing Worms to breed in them. He governeth 29 Legions
of Spirits, and his Seal is this, etc.

mermaid, he is the guide of the waters, and of ships laden with
armour; he bringeth to passe (at the commandement of his master)
that the sea shalbe rough and stormie, and shall appeare full of
shippes; he killeth men in three daies, with putrifieng their
wounds, and producing maggots into them; howbeit, they maie be all
healed with diligence, he ruleth nine and twentie legions.
