Sigil of Baphomet

[1] While the eponymous Baphomet had been depicted as a goat-headed figure since at least 1856, the goat's head inside an inverted pentagram was largely popularized by the modern Church of Satan, founded in 1966.

[2][3][4] The Church adopted the sigil of Baphomet as their official insignia, describing the symbol as the "...preeminent visual distillation of the iconoclastic philosophy of Satanism.

The Hebrew letters spell out Leviathan (לויתן), the ancient serpent from the biblical Chaoskampf, while the 1897 symbol is further augmented by the text "Samael" and "Lilith".

In his book, de Guaita also illustrates an upright pentagram with the Pentagrammaton (יהשוה) at the vertices of the pentagram: an esoteric version of the Hebrew name of Jesus, Yeshua (ישוע), by adding the letter shin (ש) in the middle of the Tetragrammaton divine name Yod-He-Vav-He (יהוה).

[7] In the formative years of the Church of Satan, this particular version of the symbol was utilized on membership cards, stationery, medallions, and most notably above the altar in the ritual chamber of the Black House.
