This is a seal of the future emperor Romanus IV, here at the very beginning of his career. Son of the general Constantine, who served Basil II, Romanus followed a distinguished military career. His success against the Petchenegs convinced Eudocia Makrembolitissa, widow of Constantine X, to take Romanus as her third husband in order to strengthen the empire against the growing menace of the Seljuk Turks. This was to no avail. The new emperor was defeated and captured by the Turks at the famous battle of Mantzikert in 1071. The next year he returned to Constantinople where he found he had been deposed, his wife had died, and he was seized by the new emperor Michael VII, blinded, and died soon afterwards.
