 In the earlier forms of the Western mitre the peaks or ‘horns’ were over the ears, rather than over the face and back of the head.The form of mitre used in the imperial mitral crown preserved this earlier form.This form of the imperial mitre-crown can be seen in the extant portraits of such emperors as Frederick III and Maximilian I The bronze effigy of Maximilian I found on his monumental cenotaph in the court church in Innsbruck has a crown with two arches which cross over the top of the mitre and the unique form of the imperial crown adopted by Maximilian as Emperor of Mexico appears to have been modeled on this form, but with the half-arches and the eagles on the circlet on the front, back and sides.
