Illustrating Charles-Philippe de Kerhallet's Contributions to Navigation and the Ocean's Currents
Spectacular large format world map, emphasizing the Ocean's currents.
The map includeds early details of the coastline of Antarctica. The map shows the various currents, shipping routes, the equator and magnetic equator, as well as excellent geographical and topographical details.
The note at the bottom left translates as follows:
No map can provide, like the Planisphere, a complete idea of European navigation in a single chart. It is based on the Paris meridian that the projection of this Planisphere has been made, on which all distant regions radiate around Paris and Europe. On this map, a summary of all the geographical, hydrographic, and meteorological knowledge acquired to date, the increasing latitudes have been calculated according to the table given by Mr. Bégat in his treatise on Geodesy. The delineation of winds and general currents and the indication of the principal routes to follow in navigation have been given based on general considerations for the Atlantic Ocean, Indian Ocean, and Pacific Ocean, by Mr. Kerhallet.
Mr. Kerhallet refers to Charles-Philippe de Kerhallet (1809–1863), a renowned French naval officer, hydrographer, and author known for his contributions to maritime navigation and meteorology. De Kerhallet wrote extensively on ocean currents, winds, and navigation routes, which were used by sailors and navigators in the mid-19th century. His work on global maritime routes and navigation was influential, and he authored key publications such as Considérations Générales sur l’Océan Atlantique, which focused on the Atlantic Ocean, and similar works for the Indian and Pacific Oceans.
