Preserved tattoos on ancient mummified human remains reveal that tattooing has been practiced throughout the world for many centuries. In 2015, scientific re-assessment of the age of the two oldest known tattooed mummies identified Ötzi as the oldest currently known example. This body, with 61 tattoos, was found embedded in glacial ice in the Alps, and was dated to 3250 BCE. In 2018, the oldest figurative tattoos in the world were discovered on two mummies from Egypt which are dated between 3351 and 3017 BCE.
