"Life is a Struggle (Golden Rider)," Gustav Klimt, 1903.
I won't go on about Klimt, you've heard it before. But this is an interesting canvas; it mixes the "modern" style of Art Nouveau with material that echoes the Pre-Raphaelites and medieval art.
Klimt painted this during a bitter time of life; three paintings he'd been commissioned for by the University of Vienna had been rejected for being "pornographic." Evidently, this was painted to hearten himself as he continued on his artistic journey, despite the critics and naysayers, symbolized by the snake.
There's a mosaic-like quality to this, as there is to some of Klimt's work. And the overall effect is almost jewel-like.
Courage, friends!
