The Baphomet in Dogme et Rituel de la Haute Magie' (1856) by Eliphas Levi references a Sema tawy (without deities) .

 leading from 

The Baphomet Boulevard 

and

H.R Giger's Egyptian Mysteries 

 

 

 

 

a) Sema tawy (without deities) on the side of statue of Khephren/Khafre 

 

 

b) The statue of Khephren/Khafre (2520-2494 BC) Enthroned, from the Valley Temple of the Pyramid of Khephren/Khafre at Giza discovered in 1860 or 1853?

c.i) Baphomet in Dogme et Rituel de la Haute Magie' (1856) by Eliphas Levi 

 

 

 

 

c.ii) The two side by side

 

The sema tawy is a mysterious configuration, but it looks as if the legs of the central pole could easily be transformed into the folded legs of the Baphomet,  and with that there are the extending parts ether side that could be transformed into hors, and wings, and the part extending from the top wuld be transformed into the central feature extending from the top of the Baphomet's head with a flame coming out of the top.

 

So this is just to be considered a good example since I don''t know when it was discovered, whether it was  really discovered a few years before or a few after the Baphomet illustration was created, and perhaps others of that style were found by then anyway
