History
The oldest known tattoo was discovered in 1991. It was found on a mummy known as Oetzi, an Iceman dated to be at least 5300 years old. His tattoos consist of horizontal and vertical lines.
There is some debate as to why the tattoos are there. The most common idea is that the tattoos were done for medicinal purposes. Oetzi's fifty-seven tattoos are located over various joints on the body.
The thought is that the tattoos were made while a form of acupuncture was administered to relieve painful joints. Today, the same sites are used for acupuncture. Other ideas range from social status and ritual markings to tribal marks or simple preference.
Prior to finding Oetzi, the Russians excavated bodies that were determined to be over 2400 years of age. These mummies were found in the Altai Mountains of Siberia.
Instead of lines, their tattoos are in the form of animals both real and imaginary. Many of these tattoos are thought to be decorative only while others appear to be a symbol of status rank.
