The two thieves in the context of "Impenitent thief"

Crucifixion is a method of capital punishment in which the condemned is tied or nailed to a large wooden cross, beam or stake and left to hang until eventual death, which could take minutes to days. It was first used as a punishment by the Achaemenids, Carthaginians, and Romans, among others. Crucifixion has been used in some countries as recently as the 21st century.

The crucifixion of Jesus is central to Christianity and the cross (in Roman Catholicism usually depicted with Jesus nailed to it) is Christianity's preeminent religious symbol. His death is the most prominent example of crucifixion in history, which in turn has led many cultures in the modern world to associate the execution method closely with Jesus and with Christian spirituality. Other figures in Christianity are traditionally believed to have undergone crucifixion as well, including Saint Peter, who Church tradition says was crucified upside-down, and Saint Andrew, who Church tradition says was crucified on an X-shaped cross. Today, limited numbers of Christians voluntarily undergo non-lethal crucifixions as a devotional practice.
