The tablion (Greek: ταβλίον) was a rectangular or trapezoidal panel embroidered on the ceremonial mantle (chlamys) of courtiers during the Byzantine Empire.
[1][2] In the middle Byzantine period, the chlamys is much more richly decorated, but is sometimes depicted without tablia.
[3] In art, the chlamys is usually depicted with the right half thrown behind the shoulder, so that only the left-hand tablion is visible.
[1][2] Although normally a symbol of civilian dress, military saints are often depicted wearing a chlamys with tablia.
[2] In the Kletorologion of 899, the term tablion is also used for a box for the emperor's personal garments, carried by his servants during processions.
