Though us Christians usually argue that Jesus was killed on a cross, the Bible doesn't unambiguously state this. The greek words in the Bible that are translated by Christians as cross are stauros and xy'lon; the former actually means stake/pole, while the latter literally means stick/tree. Death by being tied to a stake of wood, hands above head, was employed by the Romans, and this so-called crux simplex (simple cross, though not actually cross-shaped) may have been the form of death that the Bible actually describes Jesus as having had. There have been suggestions that Jesus died having been nailed to a tree. Roman documents, on the other hand, suggest that in Judea, criminals were usually crucified on a Y-shaped device. But what do you think?
