A most important class are the rings bestowed upon and worn by the higher ecclesiastics. Papal rings, among which the most noted is the “Fisherman’s Ring,” rings for cardinals and for bishops, and also occasionally in former times, for abbots, were and are still regarded with special reverence in the Roman and Greek churches. The usage of wearing rings of this type dates far back in the history of Christianity. Many examples of these rings are given, as also of others bearing Christian emblems, and of those worn by nuns, and by widows who had vowed never to re-wed. Closely connected with these religious rings, are the betrothal and wedding rings. Here it has seemed best to group together the available data, since the line of demarcation between engagement and wedding rings, though clearly enough marked to-day, is not easy to draw in regard to earlier times. A very full selection of mottoes has been added, some of which might still be used; the greater number, however, belong to a past age, upon the sentiments of which they cast interesting side lights. Rings as charms and talismans form a class apart. Often the peculiar form of the circlet was conceived to have a symbolic virtue, but more frequently the talismanic quality depended upon some curious engraved device, upon the stones set in the rings, or upon a mystic or religious inscription. Rings of healing were talismans valued for their special power to cure disease; the “cramp rings,” dated in legend back to the time of Edward the Confessor, were notable in this series. The rings of famous men and women will always be prized as mementos, and in the various chapters of this book a large number of them will be found, both rings of the mighty dead and those of distinguished living persons; among these latter we are happy to be able to produce an illustration of the inscription of President Wilson’s ring from an impression of his seal courteously made by his own hand. It shows his name engraved in Pitmanic shorthand. Our American Indians have also made their contribution to the art of ring-making, occasionally in the earlier centuries, and more especially in more recent times. Notably the Navajos of New Mexico have exhibited a considerable degree of skill in this direction. Much new information on this subject will be found in the present work. How rings are made by our jewellers of to-day, more especially by the accurate and varied mechanical methods now employed for their production, is concisely treated in a supplementary chapter. While machine-made rings can scarcely be expected to equal those executed by the hand of the true artist-goldsmith, those now produced are nevertheless objects of beauty and adornment.
