The Romans perfectly understood the situation, and this adverse balance caused them much uneasiness. Tiberius dwelt upon it in a letter to the Senate as early as 22 A.D. In that year the ædiles brought forward proposals for certain sumptuary reforms, and the Senate, probably to rid itself of a delicate question, referred the matter to the executive. Most of the emperor’s reply is interesting, but there is one particularly noteworthy paragraph. “If a reform is in truth intended, where must it begin? and how am I to restore the simplicity of ancient times?... How shall we reform the taste for dress?... How are we to deal with the peculiar articles of female vanity, and, in particular, with that rage for jewels and precious trinkets, which drains the Empire of its wealth, and sends, in exchange for bawbles, the money of the Commonwealth to foreign nations, and even to the enemies of Rome?”[33] Half a century later matters were, apparently, worse, for Pliny more than once returned to the subject. In the twelfth book of his Natural History, after enumerating the many well-known spices, perfumes, drugs, and gems, which have always made the Eastern trade of such surpassing value, he estimated that at the most moderate computation 100,000,000 sesterces, or about $4,000,000 in coin, were annually exported to Arabia and India alone; and at a time when silk was worth its weight in gold, the estimate certainly does not seem excessive. He added, “So dear do pleasures and women cost us.”[34] The drain to Egypt and the Asiatic provinces could hardly have been much less serious. Adrian almost seems to have been jealous of the former, for in his letter to Servianus, after having criticised the people, he remarked that it was also a rich and productive country “in which no one was idle,” and in which glass, paper and linen were manufactured.[35] The Syrians were both industrial and commercial. Tyre, for example, worked the raw silk of China, dyed and exported it. The glass of Tyre and Sidon was famous; the local aristocracy were merchants and manufacturers, “and, as later the riches acquired in the East flowed to Genoa and Venice, so then the commercial gains of the West flowed back to Tyre and Apamea.”[36]
