Look at the following nonsense
look at this link http://www.word-sunday.com/Files/B/Passion-b/A-Passion2-b.html
Mark stated the crucifixion almost as an aside, since his audience already knew the fate of Jesus, and since the methods of crucifixion were well known at the time. So, how did the Romans crucify Jesus? Romans either tied or nailed the condemned. The wood used could be a pole or a scaffold or a cross. In the case of a cross, the prisoner was affixed to the horizontal beam, then raised into place on the vertical pole. The cross could be a "T" shape with no overhead extension, or a "telephone pole" shape (the traditional cross).
The Watchtower is showing Jesus being lifted into position manually. The Romans were not that stupid. They affixed the prisoner to the pole whilst laying on the ground. Then they raised the post with the prisoner affixed. Disposal of the body was done in reverse. Just another example of the rebelious bethel artists.(hehe). Also I find the picture disturbing and it should not be viewed by children, but hey, this is a public edition.
