Title: Map of the Bay of Concepción of Chile

Description

This pen-and-ink and watercolor map of the Bahía de Concepción is based on an original prepared by Jorge Juan and Antonio de Ulloa in 1744 during one of their scientific expeditions to South America, with extensive additions and revisions made in the early 1780s. It shows the location of the old city of Concepción and its new location further from the sea after the city was rebuilt following the devastating earthquake of 1751. The map is oriented with north at the lower left. Latitude and the longitude are set in relation to the Royal Astronomical Observatory at Tenerife in the Canary Islands. The map depicts relief by shading and shows water depths by soundings.
