This book contains the first separate edition of a treatise on the universal origin of speech and language, extracted from the third volume of ” Monde primitif, analysé et comparé avec le monde modern”. The author, Antoine Court de Gebelin, a former Protestant pastor born in Nimes, was initiated into Freemasonry in the Parisian lodge Les Amis Réunis in 1771 and later in the Le Neuf Soeurs lodge where, in 1778, he also witnessed the initiation of Voltaire and other notable personalities such as the astronomer Lalande, the sculptor Houdon, the naturalist Lacépède, and the American ambassador to France, Benjamin Franklin. He founded the Sociéte Apollonienne, and was among the founding members of the Filalete, an esoteric fraternity with links to Freemasonry and the mystical Elus Coen sect.
The importance of this fine, rare and sought-after first edition is due to the presence of the large folded colour plate engraved by Gautier-Dagoty – one of the first to be ever printed in four colour.
