Martin van Maële drew erotica – a lot of it. His sex scenes of naked women in the throes of passion often feature a penis working alone or in herds, wielded as a massive weapon or being inflated by a hand pump. At other times, his subjects engage in flagellation and bondage, and he has a thing for young women and nuns (it’s always the erotic nuns) being squired by randy monks, satyrs, demons, other nuns and depraved older men caught in the act by their wives.

His work, much of it satirical, such as his riff on Michelin tyres (below), rivals those of his contemporaries, Felician Rops, Luc Lafnet, Joseph Apoux (do see his challenging erotic alphabet) and Aubrey Beardsley’s gigantic knobs and knockers. There’s also a nod to Kawanabe Kyôsai’s penis contests.
