Sigil is used to refer to a coat of arms or an identifying sign generally, or an occult symbol in mysticism. A sigilcould be used by a royal family on a stamp in order to make documents official. Its historic use in this way has made it a symbolic instrument of authority. Often sigilswould consist of a figure of something which would represent the family it belonged to. Sometimes these sigils were accompanied with inscriptions, e.g. a motto. Alternatively, when sigil is being used for occult symbology, it describes a movement in occultism proper or one of its magical practices. These symbols could often be deconstructed to reveal a set of simpler ones, each representing a certain aspect or practice of the larger movement. This lends a multifaceted meaning to the symbolism for different occult disciplines.
