SEGNI, BERNARDO, a Florentine historian, was born at Florence about the end of the fifteenth century. He studied law at Padua, pursued merchandise at Aquila, returned to Florence, where he was employed in state affairs by Duke Cosimo I. Segni translated the Rhetoric, Ethic, Politic, and the treatise on the Soul, of Aristotle into Italian, and subsequently engaged in a Storie Fiorentine dall' anno 1527 all' anno 1555. As he kept his history secret during his life, it was remarkable for the conscientious spirit in which it was written, and Segni will go down to posterity as one of the very best writers which Italy has produced. His history is decidedly superior to those of Varchi, Nardi, and Nerli, who have treated of nearly the same period. Segni died in 1559.
