The Structure of the Offices in the Tropologion of 8-9 cc. and in the Menaia of 9-14 CC
In this article the structure of the services is discussed on the ground of the Greek manuscript Tropologion of 8-9 cc. and Menaia of 9-14 cc., mostly from the libraries of Sinai and Grottaferrata. The research has led to the following findings. The services ofthe Tropologion of 8-9 cc. were organized by the liturgical order ofthe chants (στιχηρά εις Κύριε εκέκραξα -κανών - στιχηρά εις Αινείτε). Then in the Menaia of 9-11 cc. this structure was changed by another one - genre's structure (κάθισμα - στιχηρά εις Κύριε εκέκραξα - κανών). In the manuscripts of 12 c. more often you can trace the liturgical order again. This liturgical structure prevailed from 13-14 cc. everywhere on the score of user comfort.
