Maurus Servius Honoratus was a late fourth-century and early fifth-century grammarian, with the contemporary reputation of being the most learned man of his generation in Italy; he was the author of a set of commentaries on the works of Virgil. These works, In tria Virgilii Opera Expositio, constituted the first incunable to be printed at Florence, by Bernardo Cennini, 1471.
