Oetzi, the mummified ‘iceman’ found high in the Alps in 1991, was carrying as much equipment on him as the hikers who found him. He had tools made of copper, flint, bone and six kinds of wood: ash, viburnum, lime, dogwood, yew and birch. He wore clothes made of woven grass, tree bark, sinew and four kinds of leather: bearskin, deer hide, goat hide and calf skin.
