consideration of my opinion. I would believe that Iceman ritually killed. I have many reason I believe this. One reason I believe that he was ritually killed was because of his power. Otzi was believed to be a head chief of a clan. He was found with a copper bladed axe‚ which represented power. Someone in his clan may of been jealous of Otzi and the power that he had. So the person thought if could kill Otzi he would gain his power. Another reason to support my idea that this was a ritual killing is

Introduction Metallic yarns or threads‚ in general‚ have been known for more than 3000 years. Gold and silver were hammered into extremely thin sheets‚ then cut into ribbons and worked into fabrics. These were the first ‘man made’ fibres‚ which came thousands of years before nylon or rayon. The Persians made fabulous carpets with gold thread and the Indians‚ ornamental sarees with it. The metal threads were twisted‚ doubled or wrapped around some other thread such as cotton. With the advancement

There are four major factors that often contribute to the formation of hydrothermal copper porphyry: 1) readily available mineralizing fluid solutions that dissolve and transport metals‚ 2) openings in rocks which allow permeable flow of hydrothermal fluids and the metals that they transport in solution‚ 3) available sites within the fractured rocks which allow for deposition of the minerals from solution‚ and 4) the requisite chemical reactions that contribute to that deposition (Bateman‚ 1967)

The Iceman was discovered on the 19th September 1991 by a German couple‚ Helmut and Erika Simons‚ who were hiking near the Austrian and Italian border in the Alps. They both had wandered slightly off trail when Erika spotted a head and shoulders sticking out of the ice‚ she first thought it was a discarded doll‚ but it was later found out to be an ancient traveler now known as the Iceman.
