The dates here are good, and they come from bodies rather than from objects. Ötzi, found in glacial ice in the Alps and dated to 3250 BCE, carried 61 tattoos; radiological examination showed age- or strain-induced degeneration of his bones — osteochondrosis and slight spondylosis in the lumbar spine, wear in the knee and especially the ankle — corresponding to many of the tattooed areas, which has been read as a form of pain treatment. In 2018 the oldest figurative tattoos in the world were identified on two Egyptian mummies dated between 3351 and 3017 BCE. One of them, the naturally mummified Gebelein man from a shallow grave in upper Egypt, has two overlapping tattoos on his right forearm: a bovine, and another horned animal. He was eighteen to twenty-one when he died, so he was marked young.

By 500 BCE men in Nubia were tattooed, typically on the hands or arms and rarely on the face. A female mummy from Aksha, dated to the fourth century BCE, carries a tattoo of Bes on her thigh — Bes, the dwarfed god associated with fertility and childbirth, was a popular image tattooed onto women in both Egypt and Nubia.

Southeast Asia runs the largest living version. Sak yant originates in the Khmer Empire around the ninth century, built on indigenous mainland Southeast Asian animist tattooing practices dating back as far as 2,500 BCE, with designs influenced by Indian yantras. Sak is a native Khmer word from the Proto Mon-Khmer root *cɔkʔ, 'to prick'; yant is the sacred geometry. Carriers name three effects: something that benefits the wearer, such as eloquence; protection, which the account says is used by military personnel, police, taxi drivers and others in dangerous work; and an effect on people nearby, such as invoking fear.

Elsewhere the mark is a declaration. Many Copts have the cross tattooed on the inside of the right arm at the wrist as a sign of faith. Catholic Croats of Bosnia, especially children and women, used sicanje for protection against conversion to Islam during Ottoman rule. Among Austronesian societies tattoos were regarded as magical wards against dangers including evil spirits and illnesses, and in Rajasthan they were held to protect the wearer from evil spirits and bring good fortune.

Inference — every dated charm in this record comes from a body that did not rot. Ice, desert sand and deliberate mummification are the only three conditions under which this material reaches an excavator, and each of them is rare. Forensic pathologists note the other half of it: pigment lies encapsulated deep in the skin, so tattoos are not easily destroyed even when the skin is burned. The material survives; the person has to survive first.

Some traditions cut the design into the skin and rub the wound with ink, ashes or other agents, as an adjunct to scarification. Others hand-tap the ink in with sharpened sticks or animal bone needles fitted with clay discs, or, now, actual needles. The modern electric machine drives its needles in and out 80 to 150 times a second.

Two arguments are running. In 2011 Thailand's Culture Ministry sought to stop the tattooing of Buddha images on foreign visitors; the ministry's position and the tattooists' were both reported at the time, and this atlas prints the disagreement rather than settling it. The other argument is chemical: the European Chemicals Agency has proposed restricting the intentional use or concentration of about 4,000 substances in tattoo inks, the EU Observatory for Nanomaterials has raised nanotoxicological concerns about modern inks, and an analysis in the European Union in October 2024 found that nine out of ten blue and green inks sold were not compliant with the REACH legislation. A 2025 United States opinion poll found 37 per cent held favourable and 26 per cent unfavourable views of tattoos.
