At that time, they were made by hand in small quantities, intended mainly for military or commercial navigation, without mass production. Used intensively at sea, they were subjected to difficult conditions (humidity, salt, handling), often leading to their deterioration or loss, which explains the rarity of copies in good condition. In addition, these maps were considered strategic documents in a context of maritime rivalries between powers such as France, England and Spain. Their distribution was strictly controlled to prevent them from falling into the wrong hands. They were also regularly updated to correct errors or incorporate new discoveries, which quickly made old maps obsolete and often destroyed or replaced. Finally, many nautical charts were kept in private collections or archives, reducing their availability on the market. These factors make them rare and valuable objects, both historical tools, works of art sought after by amateurs, and magnificent decorative documents.
