To the famous episode of the descent of the life-goddess Ishtar to the infernal regions, forming part of the great Babylonian poem known as the “Gilgamesh Epic,” have been appended a few lines suggesting an idea distantly resembling that in the Greek myth of Orpheus and Eurydice. A mourner who seeks to release a loved one from the Realm of Death, is told to address himself to Tammuz (= Adonis). A festival garment is to be put on the god’s statue to induce him “to play on the flute of lapis-lazuli,” with a ring of porphyry. This divine music was believed to arouse the dead and call them to inhale the fragrance of the incense offering prepared for them.[154] The “porphyry ring” for playing the musical instrument might seem to indicate that it was some form of lyre, on which the ring could be used as a kind of plectrum, rather than a flute or other wind-instrument.

Rings made entirely of a precious stone substance were not uncommon in the time of Rameses III (1202–1170 B.C.) and later Egyptian sovereigns, but there is no evidence of their having been made at a more remote period. The prejudice against burying rings with the dead does not seem to have affected the Egyptians, for in a number of cases rings have been found on the fingers of mummies.[155]

The sardonyx was a favorite stone with the Romans of the Imperial Age, as is proved by the frequent allusions to it by the poets of this time. Of a celebrated player on the lyre, Juvenal (50–130 A.D.) says that as his hand passed over the strings the whole instrument was lighted up by the sheen of his many sardonyx rings.[156] Such a ring was regarded as a most appropriate birthday gift.[157] Another passage relates that the advocate Paulus, in order to render his address before the court more impressive, wore upon his hand a fine onyx ring which he had borrowed from a friend especially for this occasion.[158] Indeed, so highly was the stone prized that it was called the first of gems (gemma princeps sardonychus) and ivory caskets were regarded as fit receptacles for sardonyxes.[159] The value of rings set with them is shown by the fact that in Hadrian’s (76–138 A.D.) time, they were expressly associated with the gems of greatest value, such being strictly differentiated from those worth but four gold pieces each.[160]

Several rings of the Later Roman period in the British Museum are set with small diamonds. Of these the following are believed to represent original settings:[161]

No. 779. Plain solid hoop with sides cut flat. It is set with a small pointed diamond. Castellani Coll., 1872.

No. 785. Thin rounded hoop, slightly expanding upwards. Pointed diamond in raised oblong setting. From Tartûs. Franks Bequest, 1897.

No. 787. Angular hoop, projecting sharply below the shoulders, which are in the form of hollow leaves within a triangular frame. The bezel is square and contains an octahedral diamond; the sides are open and form a kind of wave pattern. Castellani Coll., 1872. 3rd century, A.D.

No. 788. Type akin to last. On either shoulder is an openwork triangle. The bezel is square and contains an octahedral diamond; on either side of the bezel is a small openwork triangle.

No. 789. Type akin to last. The lower part of the hoop has a groove running along its middle; either shoulder is cut away in a slight curve. The bezel is square, with a triangular space left open in each side and with a round opening below. It contains a diamond of octahedral form. Franks Bequest, 1897.

No. 790. Type akin to last. The hoop is rounded without; the curved excision of the shoulders is more pronounced. Two double pyramid-shaped (octahedral) diamonds are set in the bezel. A triangle is cut out of either shoulder, and two smaller triangles on either side of the bezel. Underneath the stone are two lozenge-shaped openings. Franks Bequest, 1897.
