The ankh is an ancient Egyptian hieroglyph, signifying life. Many Egyptian Gods hold the ankh, as a symbol of their lifegiving power. As an extension of Egyptians' beliefs about the afterlife, the ankh became a symbol of spiritual immortality.
Today, the ankh has extensive currency in Coptic Christian groups, as a symbol of their faith. Many Black activists use the symbol, as well as Kemetic Pagans. Due to the symbol's presence in Neil Gaiman's Sandman series (and its popularity among vampyre lifestylers), ankh pendants are common in the goth subculture, as well.
