An illuminated manuscript is a written work containing illuminations – images painted or drawn to accompany the text, often embellished with gold leaf or other special materials.
Until the invention of the printing press in the 1450s, most books were hand-written by scribes. Producing Bibles and other religious works was a common task for monks, who both enscribed and illuminated the text. Monasteries and abbeys usually contained a scriptorium – a room devoted to the copying and illustration of books.
Illumination was a popular means of indicating a book's special significance and was also common in the Muslim world, particularly the Iberian Peninsula. One of the most famous Western illuminated manuscripts is the Book of Kells, a 8th-9th century book created by Irish monks which contains the four gospels in Latin and various accompanying texts.

The earliest illuminated manuscripts were mostly religious, but from around 1100 AD, monks began to collaborate with secular scribes and illuminated secular works became more common. Many universities contained a secular scriptorium where significant works were copied and illuminated. In the 15th and 16th centuries, illuminations were sometimes added to printed books. The production of illuminated manuscripts peaked in the 14th and 15th centuries, then declined and became a rare occurence from the mid 16th century.
Types of illumination include:
(a) miniatures or small pictures incorporated into the text or occupying the whole page or part of the border;
(b) initial letters either containing scenes (historiated initials) or with elaborate decoration;
(c) borders, which may consist of miniatures but more often are composed of decorative motifs.
