En Terre Perdue: Extraits d’une œuvre en cours is a translation by the author into French of Letters from Mu (Part I), to which a “Post-Scriptum” and new drawings by Gilgian Gelzer have been added. It was published as an artist’s book in 2013 by Richard Meier (Voix Editions) in a large-format edition of 14 numbered copies, together with a reprinted version of the English-language work. The matching two-volume set contains original drawings by the artist on the inside covers of both books.
