The Order of Constantine was said to have been founded in AD343 by the Roman emperor Constantine. It received its official rules and statutes in 1190 from Isaac-Angelus Commenus; Emperor of Constantinople; and was also known as the Order of Angelics; the Order of the Golden Knights; and the Constantinian Militia of St. George. It had three ranks of members: grand cross; knight and brother-servant. The sign of the order is a red cross made up of four fleur-de-lis surrounded by a border of gold.Handcolored copperplate engraving of a knight from a religious military order from Robert von Spalart's 鈥楬istorical Picture of the Costumes of the Principal People of Antiquity and of the Middle Ages' (1796).
