About the book: year / During Great Lent, from Monday to Thursday of the first week at Great Vespers, the penitential canon of St. Andrew of Crete is read. This canon is called Great both by the multitude of thoughts and memories contained in it, and by the number of troparia it contains - about 250 (in ordinary canons there are about 30). For reading during the first week of Lent, the canon is divided into four parts, according to the number of days. On Wednesday and Thursday, several troparions are added to the Great Canon in honor of the Venerable Mary of Egypt, who came from a deep spiritual decline to high piety. The Great Canon ends with troparions in honor of its creator - St. Andrew of Crete. The Old Church Slavonic text of the canon is given with a parallel translation into modern Russian.
