Fr. Seraphim Holland
The Great Canon of St Andrew, Bishop of Crete, is the longest canon in all of our services, and is associated with Great Lent, since the only times it is appointed to be read in church are the first four nights of Great Lent (Clean Monday through Clean Thursday, at Great Compline, when it is serialized) and at Matins for Thursday of the fifth week of Great Lent, when it is read in its entirety (in this latter service, the entire life of St Mary of Egypt is also read).
