A museum label describes a medieval book as a richly decorated volume written on prepared animal skin. Which two terms does that description use?

توضیح

Prepared animal skin used as a writing surface is parchment, and the painted and gilded ornament added to such a volume is called illumination, so both halves of the label describe a hand-made manuscript. Adding printing fails because printing is a way of reproducing text mechanically rather than a form of decoration, and it belongs to the very end of the medieval centuries.
