I recall some studies which indicate that nails through the palms of
a person's hands will not support the person's weight. The nails
were actually driven through the wrists, which will support a person's
weight. I also believe that posts were actually used. I'm not sure where
the idea of a cross came from.

They used to put all the 'violent' criminals on crosses. Not as elaborate
as you see on television.
