Josef Šíma (1891-1971) was a Czech imaginative, abstract and surrealist painter, who lived in France from 1921. His sources of inspiration spanned nature, crystals, cosmic visions, landscape and female bodies, to fascination by stories of ancient mythology such as Falling Icarus or Leda and the Swan.Naming citation (MPC batch dated 2016-11-14), IAU / Minor Planet Center, via NASA/JPL
