Niccolò Barbo

[3] His death took place before 31 August, the date on which Maffeo Vallaresso addressed a letter of consolation to Barbo's brother Giovanni.

[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.

According to the heading, it was a piece of "silliness" (ineptias) composed when its author was fifteen, but much praised by his younger brother.

[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.
