 He also wrote an alternate history, "L'Empire du Baphomet" [The Empire Of Baphomet] (1972), in which an alien attempts to manipulate the Knights Templar to assume control of the world during the Crusades, and a sequel, "Croisade Stellaire" [Stellar Crusade] (1974), in which the Templars go into space to conquer Baphomet's people and convert them to Christianity.These two books were translated later into English as "Baphomet's Meteor" and "Stellar Crusade", and published together as "Cosmic Crusaders" (1980).Barbet’s other notable novels included the "Napoleons of Eridani" trilogy (1970–84), in which a squadron of Napoleonic soldiers kidnapped by aliens conquer a space empire, a theme reminiscent of Poul Anderson's "High Crusade" and the author's earlier "L'Empire du Baphomet".
