Octabae. The Octave, or Octaves. The eighth day after a festival inclusively, in other words, that day week. The celebration of the Octave is said to have arisen in the fact that the early Christians celebrated their festivals for eight days, but made the last of those days the one of greatest solemnity, on the authority of Leviticus, xxiii. 36. Octabas was the A.S. name for the Octave.
