Niccolo Barbo

Niccolò Barbo ( – 1462) was a Venetian patrician, official and Renaissance humanist.

Life Barbo was born in Venice around 1420. He was the son of Piero (Pietro) Barbo and Chiara Bocco. He was distantly related to Paolo Barbo and Pietro Barbo. He studied under George of Trebizond and Paolo della Pergola. He was presented for the to the Great Council in 1438.

In 1440, Barbo served as Venetian ambassador to Alessandria. In 1444, he was one of the officials of the wine tax and head of the Council of Forty. In 1448, he served as ambassador to the Counts of Segni.

A collection of his correspondence—eleven letters in total—is found in two manuscripts, Lat. XIV 256 and 257 in the Biblioteca Marciana. They cover the period 1438–1442. Included are letters to Paolo Barbo, Isotta Nogarola, Antonio Beccadelli, Andrea Trapesunzio, and Jacopo Rizzoni, as well as letters from Nogarola and Giovanni Pontano. Some of his correspondence is preserved outside of the collection. This includes two further letters to Nogarola and one from her, letters to and from Francesco Barbaro and letters from Maffeo Vallaresso and Guarino Veronese. In his letter to Tommaso Pontano dated 24 November 1439, Barbo defended Nogarola from anonymous accusers. The Oratio in laudem nobilissimi viri Francisci Contareni is preserved in three manuscripts. Barbo is probably also the author of a short oration preserved amongst his letters. According to the heading, it was a piece of "silliness" (ineptias) composed when its author was fifteen, but much praised by his younger brother. Also possibly belonging to Barbo is the Sermo de sancto Romualdo, which has been attributed to Marco Barbo.

Around 1440, Barbo and two of his friends, Francesco Contarini and Lauro Quirini, wrote a collective response to Poggio Bracciolini's De nobilitate. The resulting Epistola nobilium virorum patritiorum ad Petrum Thomasium Physicum postulantium iudicium in causa Poiani dialogi positi in controversia de nobilitate, which all three signed but which Quirini wrote, is a defence of the Venetian nobility.
