The Missorium of Theodosius I is a large ceremonial silver dish preserved in the Real Academia de la Historia, in Madrid, Spain. It was probably made in Constantinople for the tenth anniversary (decennalia) in 388 AD of the reign of the Emperor Theodosius I, the last Emperor to rule both the Eastern and Western Empires. It is one of the best surviving examples of Late Antique Imperial imagery and one of the finest examples of late Roman goldsmith work. It is the largest and most elaborate, and the most famous, of the 19 surviving vessels believed to represent largitio ("largesse") or a "ceremonial gift given by the emperor to a civil or military official". Iconography The dish shows a hieratic image of the Emperor framed in an arcade, giving a document contained in a diptych, possibly a letter of appointment, to a much smaller senior official, flanked by his two co-emperors, Valentinian II and his own son Arcadius, and bodyguards who can be identified by their hairstyles, torcs and shields as belonging to the German imperial bodyguard. The official receives the document with hands covered by his chlamys (cloak). Theodosius is shown far larger than the other figures, as is common in the hieratic Late Antique style, despite the fact that Valentinian II had been an Emperor for longer (he in turn is significantly larger than Arcadius or the unknown official). The three emperors have haloes which is usual at this period. Their clothing is early Byzantine dress consistent with other Imperial portraits of the period. The two co-emperors have decorated tablions (patches showing rank attached to their main garment) at their knees, or possibly Epigonations (unattached ceremonial "handkerchiefs", which survive as an Eastern Orthodox vestment). These would have been highly decorated with embroidery and probably jewels. The official receiving the document wears clothes decorated with stripes and patches which would have been a kind of uniform for his office. The three Imperial figures have tightly curled hairstyles, and wear diadems of pearls. Their cloaks are fastened with large circular jewelled fibulae, comparable to that worn by Justinian in the mosaic at San Vitale, Ravenna, while the official has a "crossbow" fibula. The architectural surround has often been compared to a peristyle at Diocletian's Palace in Split, Croatia, where the emperor retired after abdicating his powers. This opens from the imperial residence to a courtyard that has been regarded as
