The form of Greek hymns called “kontakia’ gives way in about 700 to “kanons,” long poems built on nine odes and having a mystical association with the nine scriptural canticles.

By custom, the second ode is omitted except during Lent because of its serious nature, and the use of eight odes eventually becomes typical.

Andrew of Crete, who flourishes around this time, is one of the early renowned writers of the “kanon” form.
