In ancient Egypt the scarab beetle was a sign of rebirth, as the Johns Hopkins Archaeological Museum explains in its work on Egyptian amulets. Scarab amulets were made of steatite and of glazed faience. Our files give no date for the first ones.
To verify: The Johns Hopkins page itself; our research lists it but has not yet checked it; A date for the earliest scarab amulets; A source for the materials, steatite and faience
