De remediis utriusque fortunae

De remediis utriusque fortunae ("Remedies for Fortunes") is a collection of 254 Latin dialogues written by the Italian humanist Francesco Petrarca (1304-1374), known in English as Petrarch. He composed it between 1354 and 1366, while based in Milan under Visconti patronage and later in Venice and Padua, revising and retitling it over those years; he completed it on October 4, 1366. It is divided into two books: the first, "De prosperis", treats the dangers of good fortune in 122 dialogues; the second, "De adversis", addresses adversity in 132.

The dialogues are staged between allegorical figures such as Joy, Hope and Reason. Drawing on classical sources, Petrarch recommends humility in prosperity and fortitude in adversity, showing how thought and conduct can produce happiness or, conversely, sorrow and disillusionment. The work enjoyed wide circulation: over 150 complete manuscripts and 94 abridged or translated copies survive, and the first printed edition appeared in 1468.
