The Imperial Sword was made for Emperor Otto IV in the twelfth century, possibly for his coronation as King of the Romans in 1198.
The first known explicit mention of the sword dates to 1315, in a letter of a lady-in-waiting of Elisabeth of Aragon, wife to Frederick III.
The lower edge of the pommel is inscribed with BENEDICTVS · DO[minv]S DE[v]S QVI DOCET MANV[s]+ viz (Blessed be the Lord my God, who teaches the hand [to wield]).
[1] This is an abbreviated form of Psalm 144:1, Benedictus Dominus Deus meus, qui docet manus meas ad prælium, et digitos meos ad bellum (Blessed be the Lord my strength, which teacheth my hands to fight, and my fingers to war).
The figures have been identified as depicting the consecutive German monarchs from Charlemagne to Henry III, who was crowned in 1046.
