Léon Roger (also known as Léon Roger-Milès or just Roger-Milès; 3 November 1859 – 24 May 1928)[1] was a French lawyer, historian, poet, journalist and art critic.
Born in Paris,[2] Roger-Milès was a professor at Collège-lycée Jacques-Decour from 1879 to 1887.
[3] His book Les Heures d'une Parisienne (1890) includes the titular short novel together with Pures et Impures, a collection of 21 stories.
The story "Une Vision d'Allori" is dedicated to the painter Gabriel Guay, who provided the book's cover art.
[4] In his 1923 book, Leonard de Vinci et les Jocondes, Roger-Milès argues that Leonardo actually painted at least two versions of the Mona Lisa, including one done for Francesco del Giocondo, and another for Giuliano de' Medici.
