At his coronation, he may have worn the red silk mantle that had been crafted during the reign of Roger II.[citation needed] It bore an Arabic inscription indicating that the robe dated from the year 528 in the Muslim calendar (1133-34), and incorporated a generic benediction, wishing its wearer "vast prosperity, great generosity and high splendour, fame and magnificent endowments, and the fulfilment of his wishes and hopes. May his days and nights go in pleasure without end or change." This coronation robe can be found today in the Schatzkammer of the Kunsthistorisches Museum in Vienna.
