Note 1693 — BOOK VI.

The Atrium, which was generally the principal apartment in the house, had an opening in the centre of the roof, called Compluvium, or Cavum Ædium, toward which the roof sloped so as to throw the rainwater into a cistern in the floor (commonly made of marble), called Impluvium. (See the drawings of the houses of Pansa and Sallust, Pompeii, vol. ii., p. 108, 120. Bekker's Gallus, p. 257.) The two terms are used indifferently. The Cinerarius seems to be the same as the Ciniflo (Hor., i., Sat. ii., 98, "a cinere flando," Acron. in loc.), "the slave who heated the Calamistri, or curling pins." Bekker's Gallus, p. 440.
