Niccolò Barbo

Flavio Biondo praises Barbo for his "literary accomplishment".^[5]

A collection of his correspondence—eleven letters in total—is found in two manuscripts, Lat. XIV 256 and 257 in the Biblioteca Marciana.^[1] They cover the period 1438–1442.^[6] Included are letters to Paolo Barbo, Isotta Nogarola, Antonio Beccadelli, Andrea Trapesunzio, Tommaso Pontano [it] 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.^[2] In his letter to Tommaso Pontano dated 24 November 1439, Barbo defended Nogarola from anonymous accusers.^[3]

On 27 March 1442 in Padua, Barbo delivered a speech honouring Francesco Contarini [it] when the latter received his doctorate of arts.^[7] The Oratio in laudem nobilissimi viri Francisci Contareni is preserved in three manuscripts.^[1] 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.^[2] Also possibly belonging to Barbo is the Sermo de sancto Romualdo, which has been attributed to Marco Barbo.^[8]

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.^[9]
