Construction was funded by the opulent spoils taken from the Jewish Temple

Construction was funded by the opulent spoils taken from the Jewish Temple after the Great Jewish Revolt in 70 AD led to the Siege of Jerusalem. According to a reconstructed inscription found on the site, "the emperor Vespasian ordered this new amphitheatre to be erected from his general's share of the booty." Along with the spoils, estimated 100,000 Jewish prisoners were brought back to Rome after the war, and many contributed to the massive workforce needed for construction. The slaves undertook manual labor such as working in the quarries at Tivoli where the travertine was quarried, along with lifting and transporting the quarried stones 20 miles from Tivoli to Rome. Along with this free source of unskilled labor, teams of professional Roman builders, engineers, artists, painters and decorators undertook the more specialized tasks necessary for building the Colosseum.
