"Siberia's Excalibur" may have belonged to Ivan the Terrible

In 1975, archaeologists discovered a well-preserved, 12th century sword beneath a tree in Siberia. Experts believe that the sword, found near the site of the death in battle of 14th century Russian hero Ivan Koltso, may have once belonged to the armory of Koltso's benefactor Ivan the Terrible.

Nicknamed "Siberia's Excalibur," the sword bears the words in Latin: "In the name of the mother of our saviour, eternal Lord and Saviour. Christ Jesus Christ," on one side and "In the name of the Almighty. The Mother of God. In the name of Eternal" on the reverse.
