French Leaf from a Breviary ca. 1150

This script has an oval aspect and has specific letters that make it easy to identify the script. S’s have a bar to the left, b’s with a club head, and a variation of d’s either with a curve to the ascender or a vertical d.  There are Carolingian remnants but also fusions and ligatures which places it into the Protogothic category.
