Quick Summary

The Triodion is a liturgical book used in the Eastern Orthodox Church. It contains the services from the fourth Sunday before Lent up to Easter. A key characteristic of the Triodion is that its canons typically have three odes, rather than the usual nine. This liturgical book is central to the Paschal cycle, which focuses on the feast of Christ's Resurrection. The hymns within the Triodion mark the Lenten period, preceding Easter.12
