In my research regarding the Divine Office, I found out that the Orthodox use a Psalter system call Kathisma, and that each day is assigned to a Matin (2 Kathisma) and a Vesper (1 Kathisma),
- Is it pretty much parallel to Divine Office?
- On Orthodox Wiki, I read, for example, the matin also involve 6 additional Psalm. If 1) is true, does that mean the Eastern Rite will have to chant the 6 Psalms, Canticles (how many?), plus the 2 Kathisma assigned for the matin?
- If 2) is wrong, is there some Antiphons and prayers that goes before and after each kathisma/stasis? What are the order?
