"the caprices of luxury in the Roman empire had given a prominence to pearls, as an article of commerce, which they had never had before, and have probably never had since. They, rather than emeralds and sapphires, were the typical instance of all costliest adornments (; ). The story of Cleopatra and the fact that the opening of a new pearl market was one of the alleged motives which led the Emperor Claudius to invade Britain, are indications of the value that was then set on the “goodly pearls” of the parable."
