Metatron's Cube is a two-dimensional geometric figure created from 13 equal circles with lines from the center of each circle extending out to the centers of the other 12 circles. Six circles are placed in a hexagonal pattern around a central circle, with six more extending out along the same radial lines.
Its name makes reference to Metatron, an angel mentioned in apocryphal texts including the Second Book of Enoch and the Book of the Palaces.
The Flower of Life has thirteen circles. If each circle's center is considered a "node", and each node is connected to each other node with a single line, a total of seventy-eight lines are created. Within this cube, many other shapes can be found, including two-dimensionally flattened versions of the five platonic solids. In early Kabbalist scriptures, Metatron supposedly forms the cube from his soul.
Metatron's cube is also considered a holy glyph, and was often drawn around an object or person to ward off demons and satanic powers.
