- n. Either of two regular seven-pointed stars, drawn with the construction lines retained; a heptangle.
- n. A heptagon.
The first heptagram was used as a symbol in the Kabbalah, and later by Aleister Crowley and the Ordo Templi Orientis where it was known as the Star (or Seal) of Babalon.
A hexagram—like a Star of David—has six; the heptagram has seven; here’s eight, the octogram; and nine, one form of an enneagram.
