When the Romans crucified a victim, the nails were driven through the wrists between the radial and ulna bones and not through the palms. The nail would have ripped through the palm because the palm could not withstand all the weight of the body. The reason nearly all depictions of Christ’s crucifixion show Him being nail through His palms is because it looks more visually appealing to eye.
Another example of creative license is Jesus carrying a complete cross through the streets of Jerusalem. The condemned would only be forced to carry the 50-pound crossbar. The whole cross could weigh up to 300 pounds, which be impossible for someone to carry.
