Coucher de soleil no. 1 sphere, also called Poincaré dodecahedral space, is a particular example of a homology sphere. Being a spherical 3-manifold, it is the only homology 3-sphere, besides the 3-sphere itself, with a finite fundamental group. While it is not known the extent to which such discoveries influenced Metzinger's representation of the radiating sun in "Coucher de soleil no. 1", his interest and prowess in mathematics is well documented. Coucher de soleil no. 1 Coucher de soleil no. 1 (also called Landscape, Paysage, Landschap, or Sunset No. 1) is an oil painting created circa 1906 by the French artist and theorist Jean Metzinger
