Un inedito opuscolo «De fide» d’autore incerto già attribuito a Massimo Planude

This paper provides the first edition of a Byzantine treatise on the orthodox faith, equipped with an introduction dealing with the manuscript tradition of the text, its authorship (it is not a work by Maximos Planudes, as often stated by previous scholarship; the author was presumably a monk named Neilos), its chronology (late 13th-early 14th century), its sources.
