  Of more interest is the mostly anonymously transmitted paraphrase of the Nicomachean Ethics edited in CAG 19 as the work of Heliodorus of Prusa. This attribution is clearly a hoax; in fact the only thing we know about the circumstances under which the work was composed is that it must have been before 1366, when the earliest manuscript is dated, and after the composition of Eustratios’ commentary, on which it draws. It has recently been argued (by Trizio 2011) that it originated in the milieu around the former emperor John Kantakouzenos (abdicated 1354).
