Polybius is the first among the ancient writers who mentions the Colossus of Rhodes, in enumerating the donations received by the inhabitants of the island after the fearful earthquake they experienced about 223 years before Christ. “The Rhodians,” says he, “have benefited by the catastrophe which befell them, owing to which, not only the huge Colossus, but innumerable houses and a portion of the surrounding walls were demolished.” Then follows a list of the rich gifts they received from all parts. Among the benefactors of the town of Rhodes, Polybius mentions the three kings, Ptolemy III. of Egypt, Antigonos Doson of Macedonia, and Seleucus of Syria, father of Antiochus. The elder Pliny records that the Colossus, after having stood for fifty-six years, was overthrown by an earthquake, and that it took Charès of Lindos, to whom the Rhodians had entrusted its re-construction, twelve years to complete his task. It is probable that the statue of Minerva, from 50 to 60 feet in height, which was designed and partly executed by Phidias for the Acropolis at Athens, served as a model for Charès, not only for the material, but for the conception of the Colossus and for the site on which it stood. Minerva was the patroness of Athens as the sun-god Helios was the patron of the island of Rhodes. About 150 years before Christ a certain Philo-Byzantius wrote a short treatise on the seven wonders of the ancient world.[11] In it he gives an explanation of the construction of the Colossus, but nowhere speaks of the extended legs under which vessels in full sail entered the port, nor of the beacon light. On the contrary, he mentions one sole pedestal, which was of white marble. Moreover, the statue was said to be 105 feet in height, and the great harbour entrance, according to modern research, was 350 feet wide; it could not therefore possibly reach across this space. Lastly, if the statue had stood at the entrance of the great harbour, the earthquake must have overthrown it into the sea, whereas Strabo and Pliny tell us that its fragments remained for a considerable time embedded in the earth, and attracted much attention by their wonderful size and dimensions. The following is the real truth concerning the Colossus. Towards the year 305 before Christ, Demetrius Poliorcetes laid siege to Rhodes, and the inhabitants defended themselves with so much bravery, that after a whole year of struggle and endurance, they forced the enemy to retire from the island. The Rhodians, inspired by a sentiment of piety, and excited by fervent gratitude for so signal a proof of the divine favour, commanded Charès to erect a statue to the honour of their deity. An inscription explained that the expenses of its construction were defrayed out of the sale of the materials of war left by Demetrius on his retreat from the island of Rhodes.
