But the most famous bell in connection with St. Patrick is the one known by his own name and brought with his relics by Columbkille only sixty years after the saint's death. The outer case is an exceedingly rich example of Celtic work. On a ground of brass, fine gold and silver filigree is applied, in curious interlaces and knots, and it is set with several jewels, some of large size, in green, blue, and dull red. In the front are two large tallow-cut Irish diamonds, and a third was apparently set in a place which is now vacant. On the back of the bell appears a Celtic inscription in most decorative lettering all about the edge; the literal translation of this is: "A prayer for Donnell O'Lochlain, through whom this bell shrine was made; and for Donnell, the successor of Patrick, with whom it was made; and for Cahalan O'Mulhollan, the keeper of the bell, and for Cudilig O'Immainen, with his sons, who covered it." Donald O'Lochlain was monarch of Ireland in 1083. Donald the successor of Patrick was the Abbot of Armagh, from 1091 to 1105. The others were evidently the craftsmen who worked on the shrine. In many interlaces, especially on the sides, there may be traced intricate patterns formed of serpents, but as nearly all Celtic work is similarly ornamented, there is probably nothing personal in their use in connection with the relic of St. Patrick! Patrick brought quite a bevy of workmen into Ireland about 440: some were smiths, Mac Cecht, Laebhan, and Fontchan, who were turned at once upon making of bells, while some other skilled artificers, Fairill and Tassach, made patens and chalices. St. Bridget, too, had a famous goldsmith in her train, one Bishop Coula.

The pectoral cross of St. Cuthbert of Lindisfarne is now to be seen in Durham. It was buried with the saint, and was discovered with his body. The four arms are of equal length, and not very heavy in proportion. It is of gold, made in the seventh century, and is set with garnets, a very large one in the centre, one somewhat smaller at the ends of the arms, where the lines widen considerably, and with smaller ones continuously between.

Among the many jewels which decorated the shrine of Thomas à Becket at Canterbury was a stone "with an angell of gold poynting thereunto," which was a gift from the King of France, who had had it "made into a ring and wore it on his thumb." Other stones described as being on this shrine were sumptuous, the whole being damascened with gold wire, and "in the midst of the gold, rings; or cameos of sculptured agates, carnelians, and onyx stones." A visitor to Canterbury in 1500 writes: "Everything is left far behind by a ruby not larger than a man's thumb nail, which is set to the right of the altar. The church is rather dark, and when we went to see it the sun was nearly gone down, and the weather was cloudy, yet we saw the ruby as well as if it had been in my hand. They say it was a gift of the King of France."

Possessions of one kind were often converted into another, according to changing fashions. Philippa of Lancaster had a gold collar made "out of two bottles and a turret," in 1380.

Mediæval rosaries were generally composed of beads of coral or carnelian, and often of gold and pearls as well. Marco Polo tells of a unique rosary worn by the King of Malabar; one hundred and four large pearls, with occasional rubies of great price, composed the string. Marco Polo adds: "He has to say one hundred and four prayers to his idols every morning and evening."

In the possession of the Shah of Persia is a gold casket studded with emeralds, which is said to have the magic power of rendering the owner invisible as long as he remains celibate. I fancy that this is a safe claim, for the tradition is not likely to be put to the proof in the case of a Shah! Probably there has never been an opportunity of testing the miraculous powers of the stones.

The inventory of Lord Lisle contains many interesting side lights on the jewelry of the period: "a hawthorne of gold, with twenty diamonds;" "a little tower of gold," and "a pair of beads of gold, with tassels." Filigree or chain work was termed "perry." In old papers such as inventories, registers, and the like, there are frequent mentions of buttons of "gold and perry;" in 1372 Aline Gerbuge received "one little circle of gold and perry, emeralds and balasses." Clasps and brooches were used much in the fourteenth century. They were often called "ouches," and were usually of jewelled gold. One, an image of St. George, was given by the Black Prince to John of Gaunt. The Duchess of Bretagne had among other brooches one with a white griffin, a balas ruby on its shoulder, six sapphires around it, and then six balasses, and twelve groups of pearls with diamonds.

Brooches were frequently worn by being stuck in the hat. In a curious letter from James I. to his son, the monarch writes: "I send for your wearing the Three Brethren" (evidently a group of three stones) "...but newly set... which I wolde wish you to weare alone in your hat, with a Littel black feather." To his favourite Buckingham he also sends a diamond, saying that his son will lend him also "an anker" in all probability; but he adds: "If my Babee will not spare the anker from his Mistress, he may well lend thee his round brooch to weare, and yett he shall have jewels to weare in his hat for three grate dayes."

In the fourteenth and fifteenth centuries the women wore nets in their hair, composed of gold threads adorned with pearls. At first two small long rolls by the temples were confined in these nets: later, the whole back hair was gathered into a large circular arrangement. These nets were called frets—"a fret of pearls" was considered a sufficient legacy for a duchess to leave to her daughter.

In the constant resetting and changing of jewels, many important mediæval specimens, not to mention exquisite vessels and church furniture, were melted down and done over by Benvenuto Cellini, especially at the time that Pope Clement was besieged at the Castle of St. Angelo.
