polyptidi
Polyptidi, also known as polyptychs, are a type of illuminated manuscript that originated in the Byzantine Empire during the 9th century. They are characterized by their multi-panelled format, typically consisting of three or more panels, which are often hinged together to form a book. The panels are usually decorated with intricate illustrations, often depicting religious scenes, biblical narratives, or historical events. The text is typically written in Greek, but Latin and other languages were also used. Polyptidi were often used for liturgical purposes, such as in the celebration of the Eucharist, and were highly valued for their artistic and cultural significance. They are a testament to the rich artistic and cultural heritage of the Byzantine Empire, and are now highly sought after by collectors and historians alike.
