The decoration of the initial d is very representative. The inside of this letter stands for "saints sacrifice to graves". The arc on the right side of the letter depicts Mary and Christ, and the blank space of the whole letter is supplemented by branches and leaves. At the same time, the color of the stone and the purple-red tick marks on the gold background are extremely rich, full of religious mystery, especially the contrast between flat letters and vivid branches and leaves, which adds vivid effects to the picture. In addition, in the middle of the important paragraphs of the text, each letter is also decorated, usually the whole letter is different. The diversity of techniques fully embodies the rich imagination of barbarians. In particular, the clever arrangement of characters, birds and fish images and letter shapes shows their superb decorative skills.
