For instance, Eisen’s shunga composition in ‘A Picture Book of the Many Beautiful Ways to Mess Up (Ehon midaregami)‘ is an imagined erotic encounter between a Dutch couple.
Smell an Aphrodisiac
The couple speaks to one another in languages neither understands with the woman exclaiming, “Penetrate me, so that I don´t have to wait any longer. I can’t wait any longer!” The man encourages her to smell an aphrodisiac, and in reply says, “I am an attractive man in Holland and so it should be easy for me to make you come.” The man’s words are written upside down, as if to suggest they are a foreign language (apparently Dutch), thus forcing the reader to read the conversation beginning from the lower left.
