About Celer

Lived 401 – 501 (aged 99–100). Celer was a Roman diplomat and politician.

Flavius Celer was a Byzantine general and magister officiorum under Emperor Anastasius (r. 491–518) in the early 6th century.

Biography Celer was an Illyrian though nothing is known of his early life. In 503, Emperor Anastasius named him general in the ongoing war against the Sassanid Persians in the East. In the spring of 504, he led his men to participate in the ongoing siege of Amida, but soon after left and engaged in an invasion of Persian-held territory, retaking several cities and returning with much booty. In late 504, Celer engaged in negotiations with the Persians, which resulted in a temporary truce. In 505, he was again active on the eastern frontier, but is not reported to have engaged in major operations; he did, however, continue contacts with the Persians, ransoming Amida for 1,100 pounds of gold. In autumn 506, Celer led the Byzantine negotiations with the Persians at Dara, which resulted in the conclusion of a peace treaty. sometime around 503 to 504.

In 511, Celer conspired with Emperor Anastasius in a plan to have the Patriarch of Constantinople, Macedonius, exiled by inducing Macedonius to sign a document that rejected the councils of Ephesus (431) and Chalcedon (451) and thus lose the support of the pro-Chalcedonian faction.

Celer was still in office at the time of the ascension of Emperor Justin I (r. 518–527) on 9 July 518, but was soon after removed from office (his first recorded successor was Tatianus in 520 though Symmachus may have held the position in 519). Following that, he participated in the negotiations of 519–520 with the Patriarch of Rome to end the Acacian Schism. He is described by chroniclers as wise, well-educated, a capable administrator, and personally brave. The date or manner of his death is not recorded, save for a reference to it being "unfortunate".
