 The use of a closed crown may have been adopted by the English as a way of distinguishing the English crown from the French crown, but it also had other meanings to some.For example, Henry V wore a helmet-crown of the arched type at the Battle of Agincourt which the French knight St. Remy commented was "like the imperial crown".The association of the closed crown with imperial crowns was already established in Continental Europe by the late 14th century, for example the florins minted for Charles IV, Holy Roman Emperor) sometimes show him with a closed crown (though on the commoner variety, the crown is open).
