Hello there!
I commend you for undertaking to write this paper. It sounds very fascinating to me especially, because I am a liturgiologist by training (see my home page).
The Mozarabic family of rites Thekla mentions is quite interesting in themselves. Like the Gallican rite of modern-day France (both Gallican and Mozarabic rites are essentially defunct today, except for periodic celebrations on particular high days in Toledo and elsewhere), Spain too was well known in antiquity for quickly and decisively implementing liturgical and dogmatic reform faster than any other area of Western Europe (the famous filioque council of Toledo is a case in point). Rome, on the other hand, was considered the most liturgically conservative of all the churches (Rome did not officially accept the filoque clause in the Nicene Creed until c. 1009/10 AD, over 400 years after it was officially accepted in Spain!). Nevertheless, structurally speaking, the rites of the Gallican and Mozarabic churches are very similar (at some points even identical), and although there is disagreement on the issue of its origins, I for one advocate Rome as these two rites' birthplace for reasons of geographical and cultural proximity (the East was simply too far removed in its "orient"-ation.). Pun definitely intended.
I don't know if you discuss this in your paper, but if indeed Rome did blow the winds of liturgical influence westward, I wonder to what degree the State of Spain influenced the liturgical life of the Church and vice versa. We clearly see this mutual influence in the Byzantine Church, and Rome certainly does not go too far back in the same regard.
I would share with you some quotes from Fr. Schmemann's book, but all my books are still in boxes until my family and I move and I can set up my study. Would a local college or university library near you help, especially one with a strong program
on Eastern Christian studies? Such a library is bound to have Schmemann, since Schmemann has become quite an authority on liturgical matters and will continue to be so for many, many years yet to come.
I wish you all the best in your endeavors.
In Christ,
+ Prof.
