Crucifixion was never a private event. It was always raw, and searingly public, because its purpose was to terrify the masses into submission to the authorities. Crosses often lined the main roads into cities, holding the broken writhing bodies of the condemned, or displaying the rotting corpses of the dead. The Romans even scheduled public crucifixions to coincide with religious festivals, insuring the maximum number of people present to witness the horror. Murderers, robbers, traitors, and slaves were crucified, brutally, by the thousands all over the empire and always deliberately in full public view. The horror of the cross was inescapable, and the Romans intended it to be that way.
