Evocation (Head of Christ or Inspiration from a Mosaic in Ravenna) 

"Evocation (Head of Christ or Inspiration from a Mosaic in Ravenna)" is a work by the French symbolist painter Odilon Redon (1840-1916). The work depicts a hazy, ethereal head of Christ set against a backdrop of swirling blue and gold. The painting, created with charcoal and pastel, is a testament to Redon's fascination with the mystical and the symbolic. Redon was known for his use of dreamlike imagery and the exploration of the subconscious. This piece evokes a sense of both spiritual transcendence and earthly beauty. The painting's hazy, dreamlike quality underscores Redon's unique style and his exploration of the intersection of the spiritual and the material.
