What is the common medium for creating illuminated manuscripts in Early Byzantine art?

The common medium for creating illuminated manuscripts in Early Byzantine art is ink and tempera. These materials were favored because they allowed for intricate detailing and vibrant colors, which were essential in the decoration of manuscripts. Ink was used for the text, while tempera, a medium made from pigments mixed with a water-soluble binder such as egg yolk, provided a luminous quality to the illustrations and decorations. This combination enabled artists to produce richly adorned pages, often featuring gold leaf and elaborate designs that conveyed both spiritual significance and aesthetic beauty, essential elements during the Byzantine period.

In contrast, the other materials mentioned, such as oil and acrylic, were not typically used in manuscript illumination during this time. Oil paints became more popular in later periods, particularly in the Renaissance. Charcoal and chalk were generally utilized for sketching rather than final artworks, and ceramic and glass do not pertain to manuscript creation but are more relevant to other forms of Byzantine art, such as mosaics or decorative pottery. Therefore, ink and tempera are indeed the appropriate choice for the medium commonly used in Early Byzantine illuminated manuscripts.
