Lapo da Castiglionchio the Younger was a Florentine Renaissance humanist who died in 1438 at the age of thirty-three. He took part in one of the most interesting phases of Italian Renaissance humanism and achieved in his short lifetime a modest reputation as a first-rate Greek to Latin translator. Less well known is the fact that he wrote a fair amount of prose works. One of the most interesting of these is a treatise which he composed in the year (...) of his death, entitled De curie commodis, or, On the Benefits of the Curia, a portrait of the papal Curia which is written elegantly, learnedly, earnestly, and angrily. ;The goal of this study is to discuss this dialogue in its intellectual and social contexts; there are three chapters. The first is a general introduction to Lapo's life and work, to the dialogue itself, and to the historiography on the De curie commodis. The second chapter discusses the manner in which Lapo employs the virtues in a Stoicizing fashion as persuasive tools in the environment of Italian humanism. It is argued that his particular treatment of the virtues can serve as a key for interpreting the dialogue as a whole. The third chapter touches both on social historical issues in the De curie commodis and on Lapo's defense or curial wealth. ;There has been no adequate edition of the Latin text, based on a wide enough variety of extant manuscripts, nor has the De curie commodis ever been translated into English . Therefore, a thorough critical edition of the Latin text along with an annotated English translation follows the discussion. ;The treatise has been notoriously difficult to interpret and seems often to prevaricate. The interpretive conclusion of this study is that Lapo wrote as a well-informed but liminal figure in the socio-cultural environment of the papal Curia--as an outsider who desired to become a full-fledged insider. The De curie commodis is not the parting shot of a fed-up hanger-on; it is instead Lapo's last-ditch, highly critical but nonetheless sincere attempt to find a patron who would allow him to join a cultural ambient at which he marvelled but from which he felt himself unjustly excluded.
