Antigonus I Monophthalmus, one of Alexander’s warring successors, has his son Demetrius besiege Rhodes in an attempt to break its alliance with Egypt.
Demetrius creates huge siege engines including a 180 ft (55 m) battering ram and a siege tower named Helepolis that weighs 360,000 pounds (163,293 kg).
Despite this engagement, in 304 BC, after only one year he relents and signs a peace agreement, leaving behind a huge store of military equipment.
The Rhodians sell the equipment and use the money to erect a statue of their sun god, Helios, the statue now known as Colossus of Rhodes.
