Horned helmet of Henry VIII
The horned helmet of Henry VIII (more properly called the parade armet) is the surviving part of a full suit of armour made by Konrad Seusenhofer between 1511 and 1514. The armour was a gift from the Holy Roman Emperor Maximilian I to the English king Henry VIII, following their alliance in the War of the League of Cambrai.
