The great dodecahedron is one of the four Kepler-Poinsot polyhedra, composed of twelve pentagonal faces arranged as six pairs of parallel pentagons that intersect one another to form a pentagrammic path, with five pentagons meeting at each vertex.
Facts
Partially Attested
Origin YearWikipedia credits Louis Poinsot with discovering the great dodecahedron in 1810, but the same article also notes the shape had already appeared in Wenzel Jamnitzer's 1568 Perspectiva Corporum Regularium, so 1810 marks its mathematical discovery rather than its first appearance.
