Death by nailing or binding to a wooden cross. The practice began in the ancient east and was common among the Romans as punishment inflicted on slaves and certain non-Romans. It was abolished by Constantine. The crucifixion of Christ is recorded by all four evangelists. Crosses used for execution are either crux commissa (in the form of the letter T) or crux immissa (the upright extending above the cross bar). See Cross.
