“ Becoming a teacher in a private school of his own, he made a name as profound student of literature; and after the troubles of the ’48, when he held office under the revolutionary government and was imprisoned for three years at Naples, his reputation as a lecturer on Dante at Turin brought him the appointment of professor at Zurich in 1856. He returned to Naples as minister of public instruction in 1860, and filled the same post under the Italian monarchy in 1861, 1878 and 1879, having in 1861 become a deputy in the Italian chamber. In 1871 he became professor at Naples University. ”
