With the work of an engraver. Rather, "an artificer." The engravings of a signet. Signets in Egypt were ordinarily rings, on the bezel of which the name of the owner was inscribed. Some were of solid gold; others with cylindrical bezels of glass or hard stone.
On the early use of such signet rings in Egypt see Genesis 41:42. Cylinders, strung round the wrist and engraved with a name and titles, were common in Mesopotamia from b.c. 2000. Ouches of gold. Settings in open-work or filagree seem to be intended—a kind of setting which is very common in Egyptian ornaments.
