a cross to symbolize the crucifixion. The placing of the nails in the hands, or the wrists is also uncertain. Some theories suggest that the Greek word () for hand includes the wrist and that the Romans were generally trained to place nails through Destot's space (between the capitate and lunate bones) without fracturing any bones. Another theory suggests that the Greek word for hand also includes the forearm and that the nails were placed near the radius and ulna of the forearm. Ropes may have also been used to fasten the hands in addition to the use of nails. Another issue of debate has been the use of a hypopodium as a standing platform to support the feet, given that the hands may not have been able to support the weight. In the 17th century Rasmus Bartholin considered a number of analytical scenarios of that topic. In the 20th century, forensic pathologist Frederick Zugibe performed a number of crucifixion experiments by using ropes to hang human subjects at various angles and hand positions. His experiments support an angled suspension, and a two-beamed cross, and perhaps some form of foot support, given that in an form of suspension from a straight stake (as used by the Nazis in the Dachau concentration camp during World War II), death comes rather quickly. Words of Jesus spoken from the cross The Gospels describe various last words that Jesus said while on the cross, as follows: Mark / Matthew (Aramaic for "My God, My God, why have you forsaken me?"). Aramaic linguist Steve Caruso said Jesus most likely spoke Galilean Aramaic, which would render the pronunciation of these words: . The only words of Jesus on the cross mentioned in the Mark and Matthew accounts, this is a quotation of Psalm 22. Since other verses of the same Psalm are cited in the crucifixion accounts, some commentators consider it a literary and theological creation. Geza Vermes noted the verse is cited in Aramaic rather than the usual Hebrew, and that by the time of Jesus, this phrase had become a proverbial saying in common usage. Compared to the accounts in the other Gospels, which he describes as 'theologically correct and reassuring', he considers this phrase 'unexpected, disquieting and in consequence more probable'. He describes it as bearing 'all the appearances of a genuine cry'. Raymond Brown likewise comments that he finds 'no persuasive argument
