Rigobert Bonne; 1729-1793.
Bonne, a trained mathematician, was appointed Hydrographer
to the King.
He took over the responsibility of the french hydrographic
institute ("Dépôt de la Marine") after the death of Bellin
in 1772. This position enabled Bonne to the unequaled access
to prime mapping data, which he could use successfully for
his own private business interests.
He followed in the steps of the french school of cartographic
minutiae and geographic accuracy. As such he produced, often
in collaboration with other mapmakers, a large number of excellent
His name is generally associated with a type of equal area
projection he often used after 1757.
Of note, his participation (with Janvier and Rizzi-Zannoni)
to Jean Lattré's 1762 "Atlas Moderne". But he is most well
known for the wealth of maps he prepared for Guillaume Thomas
François Raynal's "Atlas de toutes les parties connues du
globe terrestre" (1780), and also for Nicolas Desmaret*'s
"Atlas Encyclopédique" (1787, re-issued in 1827).
* Desmaret: of engineering fame for the first recorded design
of a tunnel between France and England in 1751. nd Whittle.
Carte de l'empire de la Chine et du royaume de Corée...
This map (approx. 9 3/16"X 12 9/16"), as said in the cartouche,
is only showing the eastern part of other maps prepared around
1780 (partie orientale).
The present item is dated 1786, but seems to have been printed
for the 1787 "Atlas Encyclopédique". The delineation of Japan
is very reminiscent of Bellin's, while the coastline of Korea
is still strongly influenced by d'Anville'much earlier works.
All in all it is a very antiquated representation of the area.
Notice Tokyo (Jedo), the strange shape of Okinawa (Lekeyo),
Pyongyang (Pinyan), Shanghai ..not yet important enough to
be shown! (at that time a small harbor under the control of
the nearest large town: Suzhou (Su Tcheu)).
