Abstract: The relationship between Jules Verne and his son was bumpy during the latter’s early years. From 1886 onward, a warming of the relationship began to take place, particularly through the advice and support that the father gave to his son when he read his works. Michel largely rewrote the manuscripts left by his father. He also wrote poetry, narrative fiction conforming to realist criteria, and even opera libretti, of which the present article gives examples.
