pentacle

It occurs within the pentacle symbol engraved on a pebble from the Broch of Burrian, Orkney.

A youthful figure, looking intently at the pentacle which hovers over his raised hands.

A crowned figure, having a pentacle over his crown, clasps another with hands and arms; two pentacles are under his feet.

As you know, my friend, the Pentacle is a star formed by two equilateral triangles intersecting so as to form a six-pointed star.
