One of the most unabashedly erotic images to ever grace the pages of an art history book came from the woodblock of iconic Japanese artist Katsushika Hokusai. Widely known for his G-rated, Edo-era prints like "The Great Wave at Kanagawa," the celebrated ukiyo-e painter and printmaker famously depicted a titillating love scene between a few octupi and a satisfied-looking human being. The masterpiece swiftly and simultaneously brought full frontal nudity, bestiality, and female orgasm to the forefront of fine art.
