Nikoloz Aslanis Dze Pirosmanashvili, or Niko Pirosmani, was a self-taught Georgian painter (from the Georgia that's a nation in the Caucuses, not the Georgia that's part of the US,) who lived from 1862 to 1918. He must have truly loved to paint, for he lived most of his life in utter obscurity, trading his paintings for food and shelter. He was "discovered" by the art world only toward the end of his life, and doesn't seem to have really understood what all of that fuss and bother meant. Poor Niko got sick, and with no one to look after him, soon died.
Today, Pirosmani's art is well-respected in his homeland, and he graces the Georgian 1 Lari bill:
Anyway, here are some of his paintings I enjoyed:
