Note 2 — Chapter V · THE CAROLINGIANS AND THE TENTH CENTURY
Reading edition
Opera, Basel, 1563 (whence PL), vol. II, page 343, end of the last book (IV, περὶ διδάξεων) of De elementis philosophiæ.
Loup’s first letter to Einhard puts rhetorica second (MGH, Epist. tom. VI, pars prior, page 8); and so does Rabanus, De clericorum institutione, III. xviii (PL 107: 395 B).
