Could he? Would he? If not the Tiara, why not it’s predecessor? Why not? He did bring back the older style Pallium. The Camelaucum: The pontifical mitre is of Roman origin: it is derived from a non-liturgical head-covering distinctive of the pope, the camelaucum, to which also the tiara is to be traced. The camelaucum was worn as early as the beginning of the eighth century, as is shown by tho biography of Pope Constantine I (708- 815) in the “Liber Pontificalis”. The same headcovering is also mentioned in the so-called “Donation of Constantine”. The Ninth Ordo states that the camelaucum was made of white stuff and shaped like a helmet. The coins of Sergius III (904-11) and of Benedict VII (974-83), on which St. Peter is portrayed wearing a camelaucum, give the cap the form of a cone, the original shape of the mitre.
