An illuminated manuscript is a manuscript in which the text is supplemented with such decoration as initials, borders (marginalia) and miniature illustrations. It is made from animal skin, most usually the skin of a sheep or cow. Goatskin was used too and also deer or pigskin . Illuminated Manuscripts were used by priests and monks for ritual purposes. I know all three of these questions but I cannot figure out the last question. But I hope this helps.
