Important Italian poet, essayist, philosopher, and philologist (1798-1837). Exceedingly rare ALS in Italian, one page, 4.25 x 5.75, March 15, 1819. Letter to his cousin, Conte Francesco Cassi, sending him a book. In part (translated): "On account of not trusting the mail, I waited a long time before I was offered an opportunity to send the little book that will be present with this...If you ever have this letter together with the booklet for a sign of confidence, and will read my poor verses, and reach the end, you have more friendship than I merit." Affixed to a slightly larger card. In very good condition, with heavy overall foxing. It was around this period that Leopardi began writing his major works, beginning with the first poems of the Canti in 1818 and the Idylls in 1819. A fascinating and very early letter demonstrating Leopardi's humility and admiration of his older cousin. Accompanied by a full letter of authenticity from PSA/DNA.
