DUMORTIER, HOCQUART and ARNOUL. Tableau comparatif et figuré de la hauteur des principales montagnes et du cours des principaux fleuves du monde. Paris, J. Goujon & J. Andriveau, 1842. Colour lithograph measuring 87 x 54 cm, in sheet form. The rivers are engraved by Dumortier, the mountains by Hocquart and the lettering by Arnoul. New edition (the first edition dates from 1828). Extract from the Atlas de choix ou recueil de cartes de géographie ancienne et moderne dressées par nos meilleurs auteurs (Paris, 1820-1828). An engraving that excels more for its aesthetics than for its accuracy... The highest peak in the world is in the Himalayas, named Tchhamoulari at 8576 m., followed by Dawalagiri at 8529 m. (in the 1829 edition it was listed first at 8,047 m, which was closer to its actual altitude of 8,167 m); the Andean volcanoes exceed 7,500 m, and so on. This shows just how virtually unknown the mountain ranges of Asia and South America were at the time. The peak of Tenerife, given in the Middle Ages as the highest mountain in the world, is brought back to more accurate proportions (3,766 m) and Mont-Blanc is listed at 4,797 m, which is very close to reality. Small tears without missing margins. A fine and rare proof.
