èque Nationale in Paris, France, has recently put up a black and white scan of Paris: Bibliothèque Nationale de France, MS Lat. 8884, which contains portions of a Pre-1256 Dominican Missal. The image to the left is not of the Paris MS, but of a similar Dominican Missal MS in the Dominican monastery of Lausanne.
This Missal predates the reforms by Humbert of Romans that created the standard Dominican Rite in use till the present. Those interested in the Pre-Humbert Dominican Rite may consult William Bonniwell, History of the Dominican Liturgy (New York: Wagner, 1944), pp. 29ff. This book can be downloaded in PDF format on the left sidebar of Dominican Liturgy.
The Paris MS is available for viewing here.
