Gilt bronze plaque of the 11th century depicting a military saint (Theodore) in the guise of a dismounted Byzantine cavalryman. His equipment comprises leather-fringed lamellar klibanion, sword suspended from a baldric, lance (shortened to fit the plaque) and decorated circular shield. The sash tied round his chest occurs in a number of sources and is probably an indication of rank. Most dismounted horsemen wear cloaks in the pictorial sources.
