a grammarian, born at Tusculum, was a freedman of T. Pomponius Atticus, and taught the daughter of his patron, who was afterwards married to M. Agrippa. But, suspected by Atticus of entertaining designs upon his daughter, he was dismissed. He then lived pn the most intimate terms with Cornelius Gallus; and, after the death of the latter, he opened a school at Rome for young men, and is said to have been the first to dispute in Latin extempore, and to give lectures upon Virgil and other modern poets. (Suet. Ill. Gram. 16.)
