Semon
an engraver of precious stones belonging to an early period, as is clear from the only work of his which is extant, namely, a stone in the form of a scarabaeus, engraved with the name ΣΗΜΟΝΟΣ, but in the reverse order, and in archaic characters. It is very rare to find an old Greek gem inscribed with the name of the engraver, although this was the usual practice in the Roman period. (R. Rochette, Lettre à M. Schorn, p. 153, 2d ed.)
