Jewels of this species and of this period are of the utmost rarity. Another very beautiful example was discovered at Mainz just five years after the Eagle Fibula, and is now in the collection of Baron von Heyl zu Herrnsheim at Worms. It is formed of repoussé gold, and represents an eagle standing upon a branch rolled up at both ends. A fine sapphire occupies the middle of the breast, in the centre of the wings are emeralds, the tail is set with lapis-lazuli, and the eye of the bird with a small ruby. This exquisite jewel dates from the early part of the thirteenth century. It measures 2-1/8 inches in height and 1-5/8 inches in width.[76] The most remarkable among jewels of about the same date (the twelfth century) are the splendid antique cameos already described--the Cameo of St. Hilary in the Bibliothèque Nationale, Paris, and the Schaffhausen Onyx--both of which were originally employed as pectorals or brooches.

[Illustration: _PLATE XXII_ MEDIÆVAL BROOCHES (PECTORALS AND MORSE)] A few brooches are attached, as was once the jewel of St. Hilary, as _ex voto_ on the breast of reliquary figures, like that of St. Foy at Conques, which still exhibits an ornament of this kind. A brooch or fermail (for this latter term is not confined to the ring-brooch), 1¾ inches in diameter, which once formed part of the ancient jewels of the French Crown, is in the Galerie d'Apollon of the Louvre.[77] Two exceedingly fine brooches of about the end of the twelfth century, found at Mainz in 1896 and now in the treasury of the cathedral, are described by Dr. Schneider in the _Jahrbuch der Königlich Preussischen Kunstsammlungen_ (Vol. XVIII); and a pectoral or brooch of a similar form, a large stone in the centre, surrounded by smaller ones--to take only one among many examples--is represented on the twelfth-century statue of a queen, probably intended for the Queen of Sheba, from the west portal of the church of Our Lady of Corbeil, and now at Saint-Denis.

In the case of original jewels of this kind, it is not always easy to determine whether they were articles of adornment for the clergy or the laity, and though those for ecclesiastical use probably predominate, it is only when they contain the figured representation of some religious subject that they can with certainty be identified as cope-clasps or _morses_, the French equivalent for which is _mors de chape_. Morses were frequently of extraordinary size. Monumental brasses and tombstones, especially in Germany, exhibit many examples. Adalbert of Saxony, who was administrator of the archbishopric of Mainz, and died in 1484, is represented on his tombstone in the cathedral with one measuring more than 7 inches across. Existing examples vary from 5 to 7 inches in breadth.
