What was the iceman's job?

If you are referring to Ötzi the Iceman (the 7,000 year old mummified remains of a 45 year old man found between the peaks Fineilspitze and Similaun in the Ötztal Alps, near Hauslabjoch in 1991), from forensic data gathered from the remains, he may have been a coppersmith. By the tools found on his body, he may have been a hunter or gatherer as well.

If you are referring to the job title iceman, this is someone who sold ice from a wagon or shop, and who often delivered it to homes for use in iceboxes (pre-mechanical refrigeration units).
