Solution du problème déliaque

Solution du problème déliaque (Solution to the Delian Problem) is Giacomo Casanova's 1790 mathematical treatise attempting to solve the ancient Greek challenge of doubling the cube using only a compass and straightedge. The text presents Casanova's proposed geometric construction method, complete with detailed proofs and illustrations. He submitted this work to the Paris Academy of Sciences for review and potential publication. Written in French during Casanova's later years in Bohemia, the book represents his serious engagement with mathematics and his desire for recognition in scholarly circles. The manuscript remained unpublished during his lifetime. The work stands as an intersection between classical mathematical tradition and Enlightenment-era intellectual pursuits, reflecting both the period's renewed interest in ancient problems and the broader cultural shift toward rational inquiry.

🔷 Published in 1790, this mathematical work attempted to solve the ancient "Delian problem" of doubling the cube - one of the three classic geometric problems of antiquity that had puzzled mathematicians for centuries. 🔷 While Casanova is famously known for his romantic adventures and memoir "Histoire de ma vie," he was also a mathematician who wrote several works on geometric problems and mathematical theory. 🔷 The book was written during Casanova's later years while working as a librarian at Dux Castle (now Duchcov Castle) in Bohemia, where he spent his final 13 years. 🔷 The Delian problem got its name from the legend of Apollo's oracle at Delos, which demanded that the Athenians double the size of a cubic altar to stop a plague - proving impossible with only compass and straightedge. 🔷 Though Casanova's proposed solution was ultimately incorrect (the problem was later proven impossible in 1837), it demonstrates the widespread fascination geometrical problems held for 18th-century intellectuals.
