EYE OCULAR MONOCULAR TUERTO LUSCUS LUSCULUS BASIL BORIS BULGARIAN ANA KYIV KIEV UKRAINE

 "In the land of the Blind, the one-eyed (or Luscus) is king"

(attr. to D. Erasumus) 
(Lat. Luscus - blind of one eye)
(Sp. Tuerto - from Lat. torto - a distorted adaptation from "torsion" etc.)

Note: In 1018 the emperor of Byzantium,  Basil II (not a saint), destroyed the Bulgarian Empire. He became known as "Bulgar-slayer" - he divided prisoners into groups of 100 and blinded 99 leaving a sole one-eyed (luscus or tuerto) prisoner to guide the blinded home. Wladimir of Kyiv (capital of current Ukraine) demanded from Basil II the hand of his sister Ana - the marriage led to the christianization of Ukraine and Wladimir was declared a saint.
