Note 197 — Lecture IV. GREEK AND CHRISTIAN RHETORIC.
Reading edition
Eusebius, H. E. 6. 36. 1, speaks of Origen’s sermons as διαλέξεις, whereas the original designation was ὁμιλίαι. So in Latin, Augustine uses the term disputationes of Ambrose’s sermons, Confess. 5. 13, vol. i, 118, and of his own Tract. lxxxix. in Johann. Evang. c. 5, vol. iii, pars 2, p. 719.
