Sticherarion (pl.,
STICHERA)- a liturgical chant book of the Orthodox Church, which contains stichera and other hymns of the Proper from the yearly cycle.
Sticherarion varied in content: some contained only stichera of the twelve major feasts, others -- stichera from the Lenten and Festal Triodia, the Octoechos, or the Menaia. In time, the contents of the
Sticherarion were distributed among other liturgical chant books; in Russia, only handwritten
Sticherarion have survived.
