Octoechos (Octoekhos) – a two-volume Eastern Christian liturgical book containing the Common of the season. One volume is an abridgment of the other and is known simply as the Little Octoechos, or simply the Octoechos, while the larger and more extensive book has come to be called the Great Octoechos, or Parakletike. The Little Octoechos contains eight Sunday Offices corresponding to each of the eight tones, hence the name of the book. In each tone, or mode, there are seven sets of services, which correspond to each day of the week, so that when the eight mode is completed, the first is begun again. (Day, Peter. The Liturgical Dictionary of Eastern Christianity. Wellwood, 1993. P. 210-211). The book forms part of the the collection of old prints and special collections of UCU Library.
