There is in the collection of the Imperial Kunstgewerbe Museum, Vienna, an exceptionally fine example of the watch-ring, made by Johann Putz, of Augsburg, in the seventeenth century. It has a detachable cover, cut from an emerald, on which the Austrian double-eagle has been engraved. In the same collection are two sun-dial rings; one, made in the seventeenth century, has a lid figuring a hedgehog, studded with black diamond lozenges; the other, a sixteenth century ring, bears a Greek inscription to the effect that “time removes all things and brings forgetfulness;” the sun-dial is on the inner side of this ring, which is of silver gilt. There is also a gold astrolabe ring, which when closed looks like an ordinary one; but when the connected circles are opened up, the ring constitutes a veritable astrolabe.[144] A gold “sphere-ring” in the British Museum collection has an outer hoop in two parts, working like a gimmal, and three interior hoops which are almost concealed when the ring is closed. The exterior hoop is chased; on the inner surfaces, concealed from view when the ring is closed, appears in sections the following inscription in black enamel: Verbo Dei celi firmati sunt. Dixit et creata sunt, ipse mandavit et creata sunt. (The heavens are founded in the word of God. He spoke and they were created; he commanded and they were created.) After “firmati sunt,” is the date 1555. The three interior hoops bear, enameled in black, the signs of the zodiac, stars, and other astral figures. This ring is of German workmanship.[145] In the collection of works of art bequeathed to the British Museum in 1898 by Baron Ferdinand Rothschild, and designated as the Waddesdon Bequest, there are several characteristic rings. Of these perhaps the most notable is a large finger ring of gold, enameled and set with jewels, a sixteenth century example of German workmanship. The bezel is in the form of a clasped book; on the cover is a skull, about which are four stones, sapphire, ruby, emerald, and diamond, and two toads and snakes in enamel. When the book cover is thrown back there appears a loose plate of gold, on which is enameled a recumbent figure with skull and hour-glass; on the under side of the cover is inscribed in black enamel (in capitals): SIVE VIVIMUS, SIVE MORIMUR, DOMINI SUMUS. COMMENDA DOMINO VIAM TUAM, ET SPERA IN EUM ET IPSE FACIET (Whether we live or whether we die we are the Lord’s. Commit thy way unto the Lord and trust in Him, and He shall bring it to pass). This combines the text, Romans xiv, 8 with Psalm xxxvii, 5. On the shoulders of the ring are two groups in enamel, the Fall and the Expulsion from Eden.[146]
