Otzi, The Iceman

Otzi the Iceman, (also spelled Oetzi and known also as Frozen Fritz) is the modern nickname of a well-preserved natural mummy of a man from about 3300 BC, found in 1991 in a glacier of the Otztal Alps, near the border between Austria and Italy. The nickname comes from the valley of discovery. He rivals the Egyptian "Ginger" as the oldest known human mummy, and has offered an unprecedented view on the habits of Chalcolithic (Copper Age) Europeans.

Scientific analysis

The body has been extensively examined, measured, x-rayed, and dated. Tissues and gut contents were examined microscopically, as was the pollen found on his gear. At the time of his death, Otzi was a 30-to-45-year old man, approximately 160 cm (5'3") tall.

Analysis of pollen and dust grains and the isotopic composition of his teeth's enamel indicate that he spent his childhood near the present village of Feldthurns, north of Bolzano, but later went to live in valleys about 50 km further north.

He had 57 tattoos, some of which were located on or near acupuncture points that coincide with the modern points that would be used to treat symptoms of diseases that Otzi seems to have suffered from, such as digestive parasites and osteoarthrosis. Some scientists believe that these tattoos indicate an early type of acupuncture.

His clothes, including a woven grass cloak and leather vest and shoes, were quite sophisticated.

The shoes were waterproof and wide, seemingly designed for walking across the snow; they were constructed using bearskin for the soles, deer hide for top panels, and a netting made of tree bark. Soft grass went around the foot and in the shoe and functioned like warm socks. The shoes have since been reproduced by experts and found to constitute such excellent footwear that there are plans for commercial production.

Other items found with the Iceman were a copper axe with a yew handle, a flint knife with an ash handle, a quiver full of arrows with viburnum and dogwood shafts and flint heads, and an unfinished yew longbow that was taller than he was.

Among Otzi's possessions were two species of polypore mushrooms. One of these (the birch fungus) is known to have antibacterial properties, and was likely used for medical purposes. The other was a type of tinder fungus, included with part of what appeared to be a complex firestarting kit. The kit featured pieces of over a dozen different plants, in addition to flint and pyrite for creating sparks.

Task: You have to explain : Who was Otzi, when and where he lived, when and where was found. How many kind of tools he used, how were his clothing. Did he have anything else?
