Sigils

The term sigil derives from the Latin sigillum, meaning “seal”, though it may also be related to the Hebrew סגולה (segula meaning “word, action, or item of spiritual effect, talisman”). The current use of the term is derived from Renaissance magic, which was in turn inspired by the magical traditions of antiquity.

In medieval ceremonial magic, the term sigil was commonly used to refer to occult signs which represented various angels and demons which the magician might summon. The magical training books called grimoires often listed pages of such sigils.  Such sigils were considered to be the equivalent of the true name of the spirit and thus granted the magician a supposed measure of control over the beings.

A common method of creating the sigils of certain spirits was to use kameas (magic squares) — the names of the spirits were converted to numbers, which were then located on the magic square. The locations were then connected by lines, forming an abstract figure.

The use of symbols for magical or cultic purposes has been widespread since at least the Neolithic era. Some examples from other cultures include the yantra from Hindu tantra, historical runic magic among the Germanic peoples, or the use of veves in Voudon.
