“Her body was that of a woman with a fair complexion, but her legs were those of a mule” – TSol 4:2
The name is usually associated with the hobgoblin, Empusa, who was able to assume various shapes, however in this case, she is a satyra (female satyr). Onoskelis described her purpose as follows:
“I am a spirit which has been made into a body. I recline in a den on the earth. I make my home in caves. However, I have a many-sided character. Sometimes I strangle men; sometimes I pervert them from their true natures. Most of the time, my habitats are cliffs, caves, and ravines. Frequently, I also associate with men who think of me as a woman, especially with whose skin is honey-colored, for we are of the same constellation. It is also true that they worship my star secretly and openly. They do not know that they deceive themselves and excite me to be an evil doer all the more. For they want to obtain gold by remembering (me), but I grant little to those who seriously worship me.” – TSol 4:4-7
Onoskelis then describes that she was created
“from an unexpected voice which is called a voice of the echo of a black heaven, emitted in matter.” – TSol 4:8
and that she travels by the full moon. Solomon commanded her to spin hemp to construct the ropes used for the Temple.
