the Ankh - symbol of life - thoracic vertebra of a bull (seen in cross section)
the Djed - symbol of stability - base on sacrum of a bull's spine
the Was - symbol of power and dominion - a staff featuring the head and tail of the god Set, "great of strength"
Over time, the ankh has come to symbolize life and immortality, the universe, power and life-giving air and water. Its keylike shape has also encouraged the belief it could unlock the gates of death, and it is viewed this way by the modern Rosicrucians and other hermetic orders. The Coptic Christians have used it as a symbol of life after death.The design for the pin symbolizing membership in Wolf's Head Society, Yale University, sets a wolf's head on an inverted ankh. by Wikimania 2008
