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.
In modern uses, the concept was mostly popularized by Austin Osman Spare, who published a method by which the words of a statement of intent are reduced into an abstract design; the sigil is then charged with the will of the creator. Spare's technique, now known as sigilization, has become a core element of chaos magic.1
