The Platonic solids have been known since antiquity. It has been suggested that certain carved stone balls created by the late Neolithic people of Scotland represent these shapes; however, these balls have rounded knobs rather than being polyhedral, the numbers of knobs frequently differed from the numbers of vertices of the Platonic solids, there is no ball whose knobs match the 20 vertices ...

The five Platonic solids have an Euler characteristic of 2. This simply reflects that the surface is a topological 2-sphere, and so is also true, for example, of any polyhedron which is star-shaped with respect to some interior point.
A copy of Perspectiva corporum regularium in the Metropolitan Museum of Art, open to one of the pages depicting variations of the dodecahedron. Perspectiva corporum regularium (from Latin: Perspective of the Regular Solids) is a book of perspective drawings of polyhedra by German Renaissance goldsmith Wenzel Jamnitzer, with engravings by Jost Amman, published in 1568.
The love ideally shared between family members is a form of companionate love, as is the love between close friends who have a platonic but strong friendship. Fatuous love can be exemplified by a whirlwind courtship and marriage—it has points of passion and commitment but no intimacy.
