Trying to achieve such a feat often leads to lasting glory, but it can just as often lead to truly disastrous blunders. This research study involves a case of foundation failure. Most of the information about the disaster comes from ancient texts, such as ones by Tacitus and by Tiberius, but they tell a singular story: When 50,000 people flocked to Atilius' stadium to watch a gladiator fight, 20,000 of the audience members fell to their death as the seating collapsed.
