What involves hanging a condemned person from across and leaving him to die of exhaustion and suffocation?

The method described is known as crucifixion, a brutal form of execution historically used in various cultures, most famously by the Romans. It involved nailing or binding the condemned person to a cross, where they would suffer a prolonged and agonizing death due to a combination of factors, including exhaustion, asphyxiation, and exposure. This method was often employed as a public spectacle to deter others from committing crimes.
