Papiri(an)us, Paperinus, Papirinus e l’ 'Orthographia' di Giovanni Tortelli

This paper aims at examining afresh some fragments handed down in the Orthographia of Giovanni Tortelli (about 1400-1466) and attributed by Tortelli to Papirianus, a Latin grammarian whose name, dates, work are poorly documented. The humanist was accused of being a forger by the eminent philologists Keil and Sabbadini because most of these fragments are also found in the works of Priscianus and Marius Victorinus. The study of the sources reveals nonetheless that some of them are original and authentic; the thought of Papirianus is, moreover, rather close to that found in treatises on orthography from the first and second centuries AD. The Appendix proposes hypotheses for Papiri(an)us, Papirinus, Paperinus, names that can all be attributed to the same person, the author of an Orthographia and an Analogia. The Appendix also gathers together all the texts transmitted in the Orthographia by Giovanni Tortelli under the name of "Papirianus Grammaticus".
