Metatron's cube is a plane geometric figure formed from 13 points arranged as a central point together with two concentric
regular hexagons, with every pair of points
joined by a line segment. The resulting line drawing
is the straight-line drawing of the complete graph 
on these specially placed vertices,
and therefore contains

line segments before coincident subsegments are combined visually.
In the modern terminology used by Melchizedek (1999, pp. 158-160), the 13 points are the centers of the 13 circles in the fruit of life, a selection from an extension of the flower of life pattern. The seven-circle seed of life is an earlier subconfiguration of the same overlapping circles grid.
The figure is commonly drawn together with 13 congruent circles centered at the points. It has sixfold rotational symmetry and reflection symmetry, and selected subsets of its line segments form familiar projections of the cube, octahedron, and tetrahedron. Claims that the same drawing gives exact projections of all five Platonic solids depend on the particular line segments and projections chosen and are not part of the definition.
