I recently looked at Crowleys intro to his Book of Thoth (you can download it, as well as a large amount of excellent files on the DMT Nexus) and read about the Shemhamphorasch. The word in kaballah means the 'divided name' and stands as a shortcut for all 72 names of angels, and is derived from three verses from Exodus.
The word reminds of Shem and Shaun in FW, often compared to the Osiris and Seth bros in Egyptian lore.
Whose conception was made possible by Thoth, thanks to the 5 degree of difference between the lunar orbit around the earth and the earths orbit around the sun: as these cycles do not fit (although the Babylonians erroneously thought they had found a common ground in cycles of 19 years, which cycle has been basically adapted for the Jewish calendar), at the end of the year some 5 days were necessary to make it work (the discrepancies of which were too small to notice during one lifetime).
So Ra, the solar god, ordered their father Shu (god of the air) to come between them, separating the pair with a violent storm. Shu held Nut up away from the ground to create air space in which the sun could travel. Darkness came daily, whenever Shu let let her down, but every morning she was lifted off of Geb all over again. As the god of the earth, it is Geb who causes earthquakes whenever he laughs.
The legend went that Nut (the sky) and Geb (the earth), the first lovers (compare to HCE and ALP in FW), were forbidden to procreate by the sun god Ra who feared the offspring would take over his throne. So Ra decided Nut would be unable to give birth in any month of any year.
Thoth lured the moon into slowing down, so her cycle would would be off for 5 days as compared to the sun's cycle; these five days came at the end of the Egyptian year and weren't assigned to any month, which gave Nut the opportunity to procreate and give birth to Osiris, Isis, Seth and Nephthys.
Shem the penman might also be another name for Thoth, the god of words; just as Shemhamphorasch is the word of gods.
