Marino Sanuto the Younger, born Marin Sanudo de Candia on the 22nd of May 1466, was a Venetian patrician, historian, and diarist. He is best known for his Diarii, a 58-volume record of events in Venice and the wider world from 1496 to 1533. He died in 1536.
The Diarii is Sanuto's most significant work, covering the period from the 1st of January 1496 to June 1533 across 58 volumes. Because Venice maintained relations with courts across Europe and the Ottoman East, it functions as a near-universal chronicle of its era. Publication of the Diarii began in 1879 under Rinaldo Fulin and was completed in Venice in 1903.
The Diarii spans 58 volumes. Publication was begun by Rinaldo Fulin in 1879 in collaboration with Federigo Stefani, Guglielmo Berchet, and Niccolò Barozzi, and the last volume was published in Venice in 1903.
Despite decades of work inside the Venetian senate and access to the state's secret archives, Sanuto was twice passed over for the position of official historian. The senate first appointed Andrea Navagero and, after Navagero died in 1529 without completing the task, chose Pietro Bembo. The senate only recognized Sanuto's contribution in 1531 by granting him a pension of 150 gold ducats per year.
Sanuto wrote the Itinerario per la terraferma veneziana, published in 1847 by M. Rawdon Brown; I commentari della guerra di Ferrara, an account of the war between Venice and Ercole I d'Este, published in 1829; La Spedizione di Carlo VIII, a manuscript held in the Louvre; and Le Vite dei Dogi, published in volume twenty-two of Muratori's Rerum Italicarum Scriptores in 1733.
The Altino Chronicle is a collection of legends about early Venetian history that served as a foundation for Venetian historiography. Sanuto acquired it as part of his personal library, which was especially rich in manuscripts and chronicles both Venetian and foreign. Its inclusion in his collection placed him within the tradition of systematic preservation of Venice's past.
