The Complutensis presents the following peculiar features: it lacks breath marks, the one-syllable words are accentless and the only accent on the rest of the words is merely a sign resembling the Greek acute accent, constituting what we refer to as the single-accent (monotonic) system which is used today in Greece. Nevertheless, a 12-page booklet is interposed in between the Gospel of John and the Epistle to the Romans (N.B. Acts of the Apostles is placed after the Epistle to the Hebrews) and contains The Demise of Saint Paul, the Apostle, Deacon Euthalius’s On The Time of Saint Paul’s Sermons And On His Death Through Martyrdom, as well as Hypotheseis on the Epistles, all written in Greek.  This booklet is printed in the same type of letters as in the rest of the edition, but with accents and breath marks along with a commentary “To those concerned”, where the Cardinal explains that the single-accent system is reserved only for the ancient text out of deference to it since the ancient text lacked accents and breath marks.
