The Colossus of Rhodes

Antigonus "the One-Eyed" became governor of the East after Perdiccas. Seleucus fled to Egypt and allied with Ptolemy, Cassander, and Lysimachus against Antigonus. They made peace, promising Greek cities freedom—but Cassander broke the promise. Demetrius (son of Antigonus) defeated Cassander at Thermopylae. Athens worshipped him as "The Preserver." When Demetrius and his father took royal titles, other generals did too. Demetrius besieged Rhodes for a year but failed—earning the title "Poliorcetes" (city-taker) anyway. He left his siege machines; Rhodians sold them for 300 talents and built the Colossus, a giant bronze statue of Apollo straddling the harbor. Ships sailed under its legs. After sixty years, an earthquake toppled it; 900 camels carried away the bronze. It was one of the Seven Wonders.
