In 1885, Janmot married a former student, Antoinette Currat, and returned to Lyon. He made charcoal drawings on the theme of the underworld, which can be regarded as a kind of continuation of the "Poem of the Soul", including "Purgatory" (1885) and "The End of Time" (1888). In 1887 was published in Lyon and Paris an over 500-page book entitled "Opinion of an artist on art" and includes articles previously written by Janmot. He died five years later at the age of 78.
