Sigil of Baphomet
The Sigil of Baphomet is the official insignia of the Church of Satan, founded 1966. The sigil has been called a "material pentagram" representational of carnality and earthly principles. The Church describes the symbol as the "...preeminent visual distillation of the iconoclastic philosophy of Satanism." 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.
