Publication of a seal of rock crystal in London (British Museum), with an inscription in Aramaic and Hebrew naming the bearer, one Solomon b. Azariah, as grandson (or perhaps son) of an exilarch. An identification of the bearer as Solomon, son of the Jewish exilarch Azariah b. Solomon (c. 975) and grandson of the exilarch Solomon b. Josiah (c. 951–3), is considered, as is the alternative possibility that the grandfather was the exilarch Solomon b. Hisdai (c. 730–58).
