Abstract
Among the many works by Leon Battista Alberti (1404-1472), only one manuscript - Ludi rerum mathematicarum - directly testifi es to his command of the mathematical knowledge of the time. The importance of the treatise comes from Alberti's familiarity with and revival of the Archimedes manuscripts and tradition, as well as from the fact that Ostilio Ricci used it to teach mathematics to the young Galileo. Thirteen copies are extant, but none of them can be considered complete, which explains the diffi culties of textual reconstruction. This paper uses the example of one problem - number XVII - to illustrate the complexity of the task. The solution, when reconstructed by philological methods on the basis of surviving texts, appears absurd to a mathematician (instead of a triangle with the object on top one ends up with two parallel lines). Comparison with other problems discussed by Alberti shows that he was unlikely to make such an obvious mistake. Other methods, including mathematical analysis, help identify a missing sentence that can restore the correct reading of the text.
