Illuminators were skilled artisans in the Middle Ages who specialized in creating decorative manuscripts. They used vibrant colors, gold leaf, and intricate designs to enhance texts, making them visually appealing. Their work often included illustrations, borders, and ornate initials, which helped convey the importance of the written word. These artists typically worked in monasteries or workshops, collaborating with scribes who wrote the text. Illuminators played a crucial role in preserving knowledge and culture during a time when books were rare and valuable. Their contributions can be seen in famous works like the Book of Kells and other illuminated texts.
