Pentagram

Symbols · Numbers & forms

A five-pointed star drawn in one line. Pythagorean, later magical, and ornamental uses are local; five as a count is not this figure.

Hellenic religion

  • Pentagram appears in Hellenic religion.

    Heath’s Euclid Book IV pentagon construction yields intersecting diagonals that form the pentagram star inside the pentagon, with extreme-and-mean ratios on those diagonals. A named pentagram figure in that Elements geometry, not an occult seal dump and not pentagon as the outer polygon alone.
