12. One of the most recognizable of the Byzantine Emperors would certainly be Justinian II Rhinotmetos, Emperor between 685 and 695 and once again from 705 until 711. What was striking about his appearance?
From Quiz Byzantine Emperors Are Not All Greek To Me
Answer:
His nose was cut off.
The Heraclian dynasty was founded by Heraclius. He was succeeded by his sons Constantine III and Heraclonas. The next generations were the son, grandson and great-grandson of Constantine III: respectively Constans II, Constantine IV and Justinian II.
Justinian II led an expansive politic. He regained control of Cyprus, routed most of the Slavic tribes from the Balkans and marched upon Armenia.
The cost of these many military expeditions as well as construction of splendid buildings and monuments, lead to a quite stringent taxation. Land reforms stripped the aristocracy of some of their precious privileges, so both the upper class and the lower class were quite malcontent with Justinian's reign. Finally the aristocracy and the proletariat joined forces and deposed Justinian, and as a token of his unworthiness they cut off his nose - a rather common sentence in those days.
Justinian then went in exile, spending ten years of gathering various (Byzantine and foreign) supporters. Finally in 705 he took Constantinople by ruse and started his second reign. He was the very first person with a mutilated face who gained a throne.
Justinian's Greek nickname Rhinotmetos translates quite literally to "the severed nose" or, the more common translation, "Slit nose".
Beards on Byzantine Emperors were rare. Constans II sported a long flowing beard, but alas we don't know its colour: the only remaining images I've found, are gold coins. Constans II had the nickname Pogonatos ("the bearded one"). Frederick Barbarossa, the emperor of the Holy roman Empire from 1155 until 1190, was known for his red beard.
Any Byzantine Emperor of more than two metres tall would earn the nickname Gigantas. Alas, none of them is known by this epithet, so I presume there were no Byzantine Emperors fit for a game of basketball.
Emperors in loincloth? Byzantine Emperors were too proud for this "fashion".
