Vincent van Gogh's painting of Two Crabs is visually much the same, although the National Gallery speculates that it might "probably" be an imitation[10] of a Japanese woodblock print by Hokusai.
The earlier fable was also set in German by Andre Asriel as Die Schlange und der Krebs for mixed a cappella voices as part of his 6 Fabeln nach Aesop in 1972.
