Metatron's Cube is a name for a sacred geometric figure composed of 13 equal circles with lines from the center of each circle extending out to the centers of the other 12 circles. Some New Age teachers call a variant of this figure the Fruit of Life.
The name of Metatron's Cube makes reference to Metatron, an angel mentioned in apocryphal texts including the Second Book of Enoch and the Book of the Palaces. These texts rank Metatron second only to the Abrahamic God in the hierarchy of spiritual beings. The derivation of Metatron's cube from the Flower of Life, which the Talmud clearly states was excluded from human experience during the exile from Eden, has led some scholars (including Johann Andreas Eisenmenger) to portray Metatron as the means by which humanity was given knowledge of YHVH; presumably implying that study of Metatron's cube would be necessary to understanding the fruit.
The image below does not show the dodecahedron and the icosahedron fitting the pattern of Metatron's Cube because it is a two dimensional image, If the circles are replaced with spheres and the image is completed, both the dodecahedron and the icosahedron will fit the image. Proving that Metatron's Cube does lay the foundation of the platonic solids.
