Toward the end of his life, Pichard adapted classic erotic stories such as Les Exploits d'un jeune Don Juan by Guillaume Apollinaire, The Kama-Sutra by Vatsyayana, Trois filles de leur mère by Pierre Louÿs, La Religieuse by Denis Diderot and Germinal by Émile Zola.
These works included The Kama Sutra of Vatsyayana (1883), published just before his Nights, and The Perfumed Garden of the Shaykh Nefzawi (1886), published just after it.
