Daggers like Ötzi’s may have had symbolic significance during the Copper Age.

His mummified body chiseled out of ice in 1991 has undergone extensive examination, revealing details about his life and times. The work has offered a glimpse into the everyday life of Alpine inhabitants in the late 4th millennium BC. A paper published Wednesday in PLOS One reveals the extent to which the Iceman maintained his tools and arrows, and adds to the research on the trade networks of the time.
