Colossus of Rhodes

The Colossus of Rhodes was a statue of the Greek titan-god of the sun Helios, erected in the city of Rhodes, on the Greek island of the same name, by Chares of Lindos in 280 BC. One of the Seven Wonders of the Ancient World, it was constructed to celebrate Rhodes' victory over the ruler of Cyprus, Antigonus I Monophthalmus, whose son unsuccessfully besieged Rhodes in 305 BC. Before its destruction in the earthquake of 226 BC, the Colossus of Rhodes stood over 30 metres (98 feet) high, making it one of the tallest statues of the ancient world.


Construction began in 292 BC. Ancient accounts, which differ to some degree, describe the structure as being built with iron tie bars to which brass plates were fixed to form the skin. The interior of the structure, which stood on a 15-metre (49-foot) high white marble pedestal near the Mandraki harbour entrance, was then filled with stone blocks as construction progressed. Other sources place the Colossus on a breakwater in the harbour. The statue itself was over 30 metres (98 feet) tall. Much of the iron and bronze was reforged from the various weapons Demetrius's army left behind, and the abandoned second siege tower may have been used for scaffolding around the lower levels during construction. Upper portions were built with the use of a large earthen ramp. During the building, workers would pile mounds of earth on the sides of the colossus. Upon completion all of the earth was removed and the colossus was left to stand alone. After twelve years, in 280 BC, the statue was completed. Preserved in Greek anthologies of poetry is what is believed to be the genuine dedication text for the Colossus.

Construction

The Colossus of Rhodes as imagined in a 16th-century engraving by Martin Heemskerck, part of his series of the Seven Wonders of the World.
To you, O Sun, the people of Dorian Rhodes set up this bronze statue reaching to Olympus, when they had pacified the waves of war and crowned their city with the spoils taken from the enemy. Not only over the seas but also on land did they kindle the lovely torch of freedom and independence. For to the descendants of Herakles belongs dominion over sea and land.

Modern engineers have put forward a plausible hypothesis for the statue construction, based on the technology of those days (which was not based on the modern principles of earthquake engineering), and the accounts of Philo and Pliny who both saw and described the remains.

The base pedestal was at least 60 feet (18 m) in diameter and either circular or octagonal. The feet were carved in stone and covered with thin bronze plates riveted together. Eight forged iron bars set in a radiating horizontal position formed the ankles and turned up to follow the lines of the legs while becoming progressively smaller. Individually cast curved bronze plates 60 inches (1,500 mm) square with turned-in edges were joined together by rivets through holes formed during casting to form a series of rings. The lower plates were 1 inch (25 mm) in thickness to the knee and 3/4 inch thick from knee to abdomen, while the upper plates were 1/4 to 1/2 inch thick except where additional strength was required at joints such as the shoulder, neck, etc.

Destruction

The statue stood for 54 years until Rhodes was hit by the 226 BC earthquake, when significant damage was also done to large portions of the city, including the harbour and commercial buildings, which were destroyed. The statue snapped at the knees and fell over onto the land. Ptolemy III offered to pay for the reconstruction of the statue, but the oracle of Delphi made the Rhodians afraid that they had offended Helios, and they declined to rebuild it.

The remains lay on the ground as described by Strabo (xiv.2.5) for over 800 years, and even broken, they were so impressive that many travelled to see them. Pliny the Elder remarked that few people could wrap their arms around the fallen thumb and that each of its fingers was larger than most statues.

In 653, an Arab force under Muslim caliph Muawiyah I captured Rhodes, and according to The Chronicle of Theophanes the Confessor, the statue was cast down and sold to a Jewish merchant of Edessa who loaded the bronze on 900 camels. The Arab destruction and the purported sale to a Jew possibly originated as a powerful metaphor for Nebuchadnezzar's dream of the destruction of a great statue.
