i read in the book "Fatith in the Byzantine World" by Mary Cunningham that between the 6th and 9th centuries in the Byzantine Church, there existed two seperate rites which was for cathedral and monastic rite liturgies. The book describes the cathedral rite being more splendid and the monastic being repetitive, with the monastic supplanting the cathedral in popularity. I do not understand what rites this book is refering to, is it a eucharistic liturgy or something else maybe?
also there were "stational liturgies" from church to church but this ceased as the church building became more prominent, and the liturgy moved indoors from the 8th century onward. which is rather interesting.
