This Gradual has connections to Northern France, and the Sens Archdiocese specifically. Dated to the XIV Century (after 1297).
This Gradual has connections to Northern France, due to style of foliation, the Mass for St. Louis, and absence of certain customs. The Alleluia verses and the sequences allow a secure identification of the origins of Iluminado 84 in Sens. Specifically, the examination of the sequences demonstrates that Iluminado 84 can be considered as the oldest surviving manuscript transmitting some of the earlier sequences for Sens fully notated.
