Octavius Morgan, Esq., F.R.S., F.S.A., exhibited at a meeting of the Society of Antiquaries (February 1857) a rare and curious ‘Trinity’ ring, turned out of one piece of ivory, and belonging to the latter part of the seventeenth century. It is formed by a single band of ivory, making three circuits, so intertwined with one another as not to touch, and thus forming a threefold ring. ‘Its curiosity is great,’ remarked Mr. Morgan, ‘because these rings were only made by one person; so much art and skill were required in the making that they were the wonder of the time, and no one at the present day knows by what contrivance they were turned, or how they could now be made. The interest consists in having ascertained the maker of the ring, which I by chance met with some years ago in this city.... We find from Doppelmayer that Stephan Zick (born 1639), the artist to whom I attribute this ring, was descended from a Nuremberg family long famous for their skill in this art.... Doppelmayer, describing some of the wonderful objects which he produced, says, the work which most distinguished him was his Trinity rings. Of these he made only three; the two first were in the Museums of Vienna and Dresden, and the third became the property of an amateur collector of curiosities in Nuremberg as a wonderful work of art and skill. This was written in 1730. On comparing this ring with the engraving in Doppelmayer, it exactly corresponds. The little box turned as a case for it shows how it was cared for, and is indicative of the period when it was made. We also learn from Doppelmayer that these Trinity rings seem to have been first made in gold by a jeweller of Nuremberg, Johan Heel, about 1670, and he describes them as consisting of a single piece of wire, forming a three-fold circuit, each circuit skilfully intertwined with the other two so as not to touch each other, the ends being so cleverly united that the point of juncture could not be discovered. Thus there were three rings in one, and hence the name. The inventor of these ingenious rings is not known, but it is considered to be a Jesuit, named Scherern, about 1660. It certainly required great skill to have turned such a ring out of one piece of ivory, a work which I believe it is not possible to accomplish with any machinery now in use. The inference I draw from the foregoing is, that if Stephan Zick alone could make these rings of ivory--if he only made three, and that if one of these is at Vienna, and another at Dresden, I must now be the fortunate possessor of the third.’ [Illustration: Ivory-turned rings.] (The greatest progress in ivory-carving was made in Flanders, Holland, and Germany, about the middle of the sixteenth century. There are in the museums of Munich, Vienna, and Berlin, a quantity of ivory vases, etc., covered with exquisite carvings.--_Labarte._)
