This painting is titled Wonderland (originally Underlandet), created in 1894 by the renowned Swedish writer and artist August Strindberg. The artwork is a dreamlike, abstract landscape characterized by thick, expressive brushwork and a heavy use of a palette knife to apply oil paint. A luminous, glowing white and pale blue "opening" dominates the center of the piece, often interpreted as a clearing in a dark forest. The center is surrounded by deep greens, blacks, and browns that suggest a dense thicket. Small touches of pink and red dots near the bottom resemble scattered flowers.
August Strindberg (1849–1912) was a Swedish playwright and novelist and a pioneering self-taught painter. Often painting during personal crises, he created roughly 100 dramatic, expressionistic landscapes and seascapes focused on turbulent nature and moody, subjective depictions of sea and sky.
