Introduction It connects vices with the theme of the section of idolatry via a moral interpretation of the beast of Apocalypse 13-14, on the basis of Alexander of Hales: adoring the beast with seven heads means to commit the seven capital sins both mentally and factually. There is in fact a triple form of idolatry, that of infidels (Jews and Muslims); that of heretics; that of bad Christians (i.e. sinners). Worshiped by God “Bestia itaque est diabolus, imago vero illius est peccatum. Septem autem capita eius sunt septem mortalia peccata, que tunc adoratur cum peccatur” (f. v3r).
