• Tierce, or Terza , is the first division of the canonical day, from six to nine; Nones, or Nona , the third, from twelve to three in the afternoon. See note 526 . The bells of the Abbey within the old walls of Florence still rang these hours in Dante’s time, and measured the day of the Florentines, like the bells of morning, noon, and night in our New England towns. In the Convito , IV 23, Dante says:⁠— “The service of the first part of the day, that is, of Tierce, is said at the end of it; and that of the third and fourth, at the beginning.⁠ ⁠… And therefore be it known unto all, that properly Nones should always ring at the beginning of the seventh hour of the day.” ↩
