The two finest specimens ever seen were in the possession of the celebrated Cleopatra, who, on being sumptuously feasted by Mark Antony, derided him for the meanness of his entertainment; and on his demanding how she could go beyond him in such a matter, answered that she would spend upon him in one supper ten millions of sestertii. Antony, conceiving it impossible for her to make good her boast, laid a great wager with her about it. When the supper came, although it was such as to befit the condition of the hostess and guests, it presented no extraordinary appearance; so that Antony jeered the queen on the subject, asking by way of mockery a sight of the bill of fare; whereupon she affirmed, that what had as yet been brought to table was not to be reckoned in the count, but that even her own part of the supper should cost sixty millions. She then ordered the second service to be brought in. The servants placed before her a cruet of vinegar, and she put into it one of the pearls which were appended to her ears. When it was dissolved, she took up the vessel, and drank its contents; on which Lucius Plancus declared that she had gained the wager. Afterwards, when Cleopatra was taken prisoner and deprived of her royal estate, the other pearl was cut into two, and affixed to the ears of the statue of Venus in the Pantheon at Rome. The tenth book speaks of birds, beginning with the larger species, and concluding with remarks on generation, the food of animals, and other circumstances of a general nature. He believes that the spinal marrow of a man, as many persons have asserted, may turn into a snake; that salamanders, eels, and oysters, are neither male nor female; and that young vipers make their way through the sides of their mother. His History of Birds is extremely meagre and incorrect; but many amusing particulars are related by him, of which we select two examples.
