From The Guardian:
ShareAs he prepared to climb the scaffold to be publicly executed by guillotine on 21 January 1793, Louis XVI is reported to have asked: “Is there news of Monsieur de la Pérouse?”
He was referring to Jean-François de Galaup, the count of Pérouse, a naval officer and navigator whom the French king had dispatched in 1785 on a round-the-world scientific mission to rival discoveries made by the English explorer Captain James Cook.
The two ships under La Pérouse’s command, La Boussole and L’Astrolabe, disappeared three years later after leaving Botany Bay in Australia. The wrecks were only formally identified in 2005 and exactly what happened to them remains a mystery to this day.
Now rare letters written by an illustrious scientist who perished in 1788 have resurfaced, giving a new and personal account of the voyage. They are described as veiled love letters addressed to the married daughter of an aristocratic family, and were discovered hidden in a book of engravings being examined in preparation for auction.
Ludovic Miran, a book and manuscript expert for the auctioneers selling the letters next month, described the find as “a miracle”.
“We have a certain number of documents from the expedition but they are almost all scientific, so these personal letters are extremely rare,” Miran told the Guardian. “They throw a completely new light on what is in France an extraordinary scientific and historical event.” (Read more.)
