Crucifixion was conducted, under Roman auspices, by a _carnifex_, or hangman, assisted by a band of soldiers. At Rome, execution was done under the supervision of the _Triumviri Capitales_. The duty of the soldiers was not only to erect the cross and nail the victim to it, but also to watch him until he was dead. This was a necessary precaution to prevent friends and relatives from taking the criminal down and from carrying him away, since he sometimes continued to live upon the cross during several days. If taken down in time, the suffering man might easily be resuscitated and restored to health. Josephus tells us that three victims were ordered to be taken down by Titus at his request, and that one of them recovered. "In the later persecutions of the Christians, the guards remained four or six days by the dead, in order to secure them to the wild beasts and to cut off all possibility of burial and resurrection; and in Lyons the Christians were not once able by offers of much gold to obtain the privilege of showing compassion upon the victims of the pagan popular fury. Sometimes, however, particularly on festival days, e.g., the birthdays of the emperors, the corpse was given up to the friends of the deceased, either for money or without money, although even Augustus could be cruel enough to turn a deaf ear to the entreaties of the condemned for sepulture."[25] Roman records tell us that the soldiers frequently hastened death by breaking the legs of the criminal; at other times, fires were built about the cross beneath him; and, again, wild beasts were turned loose upon him. It was the general custom to allow the body to remain and rot upon the cross, or to be devoured by wild beasts and birds of prey. "Distracted relatives and friends saw the birds of prey attack the very faces of those whom they loved; and piety often took pains to scare away the birds by day and the beasts by night, or to outwit the guards that watched the dead."[26] Sepulture was generally forbidden by law, though there were exceptions to the rule. At the request of Joseph of Arimathea, Pilate consented that Jesus should be taken down and buried.[27] A national exception seems also to have been made in the case of the Jews on account of the requirements of Deut. xxi. 22, 23. _Pathology._--The following pathological phases of death by crucifixion are from a treatise by the celebrated physician, Richter (in John's "Bibl. Arch."), which have been reproduced in Strong and McClintock's "Cyclopedia": "(1) The unnatural position and violent tension of the body, which cause a painful sensation from the least motion. "(2) The nails, being driven through parts of the hands and feet which are full of nerves and tendons (and yet at a distance from the heart) create the most exquisite anguish. "(3) The exposure of so many wounds and lacerations brings on inflammation, which tends to become gangrene, and every movement increases the poignancy of suffering.
