I stood in front of this painting for a few minutes, trying to figure out what I'm seeing. I saw a man's feet, another set of feet, smaller or maybe it seems like it's smaller due to being a bit far, horse legs, a cross and hands that seem to be of a woman. I suppose dreams appear like this, a bit disorganized.
I think I see a horse in this image. Or at the very least, elements of the horse's anatomy. There appears to be a pony tail, a head, and then various bits and pieces along the way. It reminds me in a way of another painting by Marcel Duchamp.
This painting is called "Nude Descending a Stair Case" - but it is an abstract, one that focuses on the discrete snapshots of motion from moment to moment, and the painting you shared and image of (and your thoughts upon) seems to reference this same concept of movement distilled into a single image.
