Mr. Simpson, the King's jeweler, showed me a most rich agate cup, of an escalop-shape, and having a figure of Cleopatra at the scroll, her body, hair, mantle, and veil, of the several natural colors. It was supported by a half Mark Antony, the colors rarely natural, and the work truly antique, but I conceived they were of several pieces; had they been all of one stone, it were invaluable.
