Elsewhere has been set forth the impracticability of dissolving a pearl in a glass of vinegar without first pulverizing it.[374] It seems probable that if Pliny’s interesting story has any foundation, Cleopatra might have swallowed a solid pearl in a glass of wine—certainly a more pleasing draught as well as a more graphic sacrifice; and we should accept its reported value with a grain of salt, for it would scarcely have been safe for the court gossip to belittle the value of this tribute of love. Pliny, and other Roman writers, mention another instance, that of Clodius “the sonne of Aesope the Tragedian Poet,” who took two pearls of great price “in a braverie, and to know what tast pearles had, mortified them in venegre, and drunke them up. And finding them to content his palat wondrous well, because he would not have all the pleasure by himselfe, and know the goodnesse thereof alone, he gave to every guest at his table one pearle apeece to drinke in like manner.”[375] The chronicler fails to tell what the guests thought of the flavor of pearls, or whether some would not have preferred them for a more appropriate use. XIII VALUES AND COMMERCE OF PEARLS XIII VALUES AND COMMERCE OF PEARLS A pearl, Whose price hath launch’d above a thousand ships, And turn’d crown’d kings to merchants. _Troilus and Cressida_, Act II, sc. 2. To trace the markets of the pearl is to trace the routes of commerce from early times. The first routes from the Far East seem to have been two: one by the Persian Gulf and the Euphrates to Babylonia and Assyria, and thence by caravan through Damascus to Tyre and Sidon; the other by the Red Sea and Suez to Egypt. As regards the former route, Sir George Birdwood furnishes positive evidence that the Phenicians visited India as early as 2200 B.C. It seems highly probable that pearls were introduced by this route at an early period, although it is difficult to find material proof of the fact. By means of this commerce, the great ancient civilizations of Phenicia, Mesapotamia and the Nile valley doubtless became familiar with the gem treasures of eastern Asia. Then came the opening of the Mediterranean with first “the great Sidon,” and later Tyre, as the starting-points of commerce, exploration, and colonial settlement among the islands and on the shores of what, to the Asiatic peoples, was the great western sea. However, as the Greek islands and their colonies developed, the Phenicians were more strictly confined to the coasts of Africa and Spain. Gades, Tartessus, and Carthage were their great colonies and trading-ports, and their adventurous sailors passed on through the Straits of Gibraltar and directed their course northward to the British Isles, where they very probably obtained the pearls of the Scotch rivers.
