(demon Belphegor from Collin de Plancy's Dictionnaire Infernal, 1863)
Belphegor is the demon of ingenious discoveries and inventions. His name appears to be a corruption of the biblical name Baal-Peor, an idol worshipped in Shittim by the Israelites (Numbers 25:3). This worship may have involved sexual rituals conducted with the "daughters of Moab," suggesting that Baal-Peor was a fertility god. As is usually the case, there is no connection between the qualities of the demon Belphegor and those of the god Baal-Peor, even though the name of the god inspired the name of the demon.
