Greek term meaning "the destroyer." Obviously derived from the name of the Greek solar deity (and hence, god of growth), Apollo. This implies that the ancients understood that with energy of growth necessarily came the energy of destruction. With the rise of Christianity, Apollyon became a synonym of Satan. Although the name Apollyon appears in many grimoires, it is up to the magician using the grimoire to determine whether the use represents the positive and necessary energy of dissolution or is simply a Satanic alias.
