I think this painting is about how water can cleanse people and animals. The medium is Prints, print, color woodblock print. I chose this painting because I thought it was interesting that they were just standing in the middle of the waterfall cleaning a horse and I wanted to read about it. The style is 19th century or Edo period, the Edo period was from 1603 to 1867. The artist, Katsushika Hokusai was Japanese and died in 1849. Yes, because the horse may stand for strength, because it is standing in the middle of a fast flowing waterfall and not falling over. The overall mood is nervous, because the two men do not want the horse to fall over in the water and get injured.
