Changing interpretations of the iceman's cause of death, from the time of his discovery to the present.



Since its discovery, the iceman mummy has undergone a large amount of examinations from which scientists have gathered bits of information about his last steps on Earth, ranging from his last meal (red deer meat and possibly cereal some 4 hours before his death) to his age when he died (35-40). The cause of the iceman's death has been under scrutiny since the discovery and many theories and speculations have arisen regarding 'what happened'. These theories have developed and changed throughout the past two decades, some being the iceman being caught in a storm, an attack from a wild animal, the disaster theory, a ritual sacrifice and finally homicide. Scientists at first speculated that Otzi was killed by hypothermia from exposure to the snow in extreme weather conditions, his body then buried under thick blankets of snow and ice which would preserve his body.This was initially presumed because of no obvious physical damages, however quickly changed. Early x-rays and CAT scans taken Innsbruck appeared to show broken ribs on the iceman's right side. This discovery gave way to theories of an attack on the iceman, possibly by a wild animal that would of had the force to break Otzi's ribs. The disaster theory ties in with this as it depicts the story of the iceman getting into an argument or fight with another civilian and receiving broken ribs during the fight, then fleeing to the alps where he would die of exhaustion. Further support for this theory is the deep wound on the iceman's hand discovered through microscopical analysis. It is believed to have occurred day or two before the 'final blow', this is known as analysis has proved it had begun to heal before his death. These theories were set aside when re-examination of the iceman's body showed that he did not have a broken rib, although the overlapping of his ribs which would have been bent out of shape after death, may have given the appearance of a fracture. A new scientific break through showed evidence of an arrow head embedded in his body. The theory regarding ritual sacrifice was by a UK space technology professor from Bristol University and other sources. It was suggested that the Iceman's death may be connected to the landing of an asteroid in Austria around 3000 B.C. It was theorised that Ötzi may have been sacrificed to appease the gods who were responsible for the asteroid's crash. The asteroid event is reportedly mentioned on an Assyrian tablet discovered in during the 19th century in northern Iraq which gives further support to the theory. It is believed that the iceman could have been buried after the ritual which would explain why his body was so well preserved from not being exposed to the elements. Another means of speculation regarding this theory is the copper axe found with the iceman. It has been suggested that he ax may have been deliberately left with the body during a ritual of sacrifice to serve the iceman in the afterlife or as a tribute to the gods. The most recent theory to date of the iceman's cause of death has been most supported with distinct medical evidence. The iceman's body was scanned with computed tomography (CT) and a lesion of an artery was found near the shoulder, underneath the clavicle bone. It has been concluded that the iceman's death is a case of homicide. A single arrowhead was shot at the Otzi the iceman from an attacker positioned behind and below him. The arrow struck the iceman's left shoulder blade, the precise area where prehistoric hunters aimed to bring down wild animals with one shot. The arrow cut through his bone and pierced the artery, causing blood to instantly gush out and fill the space between the shoulder blade ribs. The iceman experienced what is now known as hermorrhagic shock, in the last few minutes of his life. Through ancient and modern scientific and medical data it can be divulged that the Iceman's heart would of began to race as sweat drenched his garments. He would of felt increasingly faint due to loss of oxygen reaching his brain. In the space of a few minutes, the Iceman collapsed, lost consciousness, and bled to death. Even though the cause of death of the Iceman, Otzi, has finally been revealed with strong scientific and medical evidence. The intentions of Otzi's killer can never be known however theories regarding this aspect of his death continue to arise. These theories and propositions can not be proven without word from the iceman's killer himself, however aim to suffice human curiosity and search for knowledge of the past.
