XX. If Crete was in decline, Rhodes, on the contrary, was extending its commerce, which took gradually the place of that of the maritime towns of Ionia and Caria. Already inhabited, in the time of Homer, by a numerous population, and containing three important towns, Lindos, Ialysus, and Camirus,[455] the isle was, in the fifth century of Rome, the first maritime power after Carthage. The town of Rhodes, built during the war of the Peloponnesus (346), had, like the Punic city, two ports, one for merchant vessels, the other for ships of war. The right of anchorage produced a revenue of a million of drachmas a year.[456] The Rhodians had founded colonies on different points of the Mediterranean shore,[457] and entertained friendly relations with a great number of towns from which they received more than once succours and presents.[458] They possessed upon the neighbouring Asiatic continent tributary towns, such as Caunus and Stratonicea, which paid them 120 talents (700,000 francs [£28,000]). The navigation of the Bosphorus, of which they strove to maintain the passage free, soon belonged to them almost exclusively.[459] All the maritime commerce from the Nile to the Palus Mæotis thus fell into their hands. Laden with slaves, cattle, honey, wax, and salt meats,[460] their ships went to fetch on the coast of the Cimmerian Bosphorus (_Sea of Azof_) the wheat then very celebrated,[461] and to carry wines and oils to the northern coast of Asia Minor. By means of its fleets, though its land army was composed wholly of foreigners,[462] Rhodes several times made war with success. She contended with Athens, especially from 397 to 399; she resisted victoriously, in 450, Demetrius Poliorcetes, and owed her safety to the respect of this prince for a magnificent painting of Ialysus, the work of Protogenes.[463] During the campaigns of the Romans in Macedonia and Asia, she furnished them with considerable fleets.[464] Her naval force was maintained until the civil war which followed the death of Cæsar, but was then annihilated.
The celebrity of Rhodes was no less great in arts and letters than in commerce. After the reign of Alexander, it became the seat of a famous school of sculpture and painting, from which issued Protogenes and the authors of the _Laocoon_ and the _Farnese Bull_. The town contained three thousand statues,[465] and a hundred and six colossi, among others the famous Statue of the Sun, one of the seven wonders of the world, a hundred and five feet high, the cost of which had been three thousand talents (17,400,000 francs [£696,000]).[466] The school of rhetoric at Rhodes was frequented by students who repaired thither from all parts of Greece, and Cæsar, as well as Cicero, went there to perfect themselves in the art of oratory.
