Stanislas de Guaita first published this pentagram in La Clef de la Magie Noire in 1897. It is the first known appearance of the pentagram and goat-head combination and is the primary influence on the Baphomet Pentagram, the official symbol of the modern Church of Satan.
SamaelSamael is a fallen angel in Judeo-Christian lore, often associated with the tempting serpent in Eden as well as with Satan. Samael also has more noble roles within the literature, but the darker, more Satanic connections are probably what was of import here.
LilithIn Judeo-Christian lore, Lilith is Adam's first wife who rebelled against his authority and became a mother of demons. According to the Alphabet of Ben-Sira, Lilith takes Samael as a lover after her rebellion from Eden.
