A tattoo is a marking made by inserting indelible ink into the dermis layer of the skin to change the pigment for decorative or other reasons. Tattoos on humans are a type of decorative body modification, while tattoos on animals are most commonly used for identification or branding. The term "tattoo" or from Samoa, "Tatau" is first referred to by Joseph Banks, the naturalist aboard Cook's ship the "Endeavour" in 1769 where he mentions it in his journal. To paraphrase. he states, "I shall now mention the way they mark themselves indelibly, each of them is so marked by their humor or disposition".
Tattooing has been practiced for centuries worldwide. The Ainu, the indigenous people of Japan, traditionally wore facial tattoos. Today one can find Berbers of Tamazgha (North Africa), Māori of New Zealand, Arabic people in East-Turkey and Atayal of Taiwan with facial tattoos. Tattooing was widespread among Polynesian peoples and among certain tribal groups in the Taiwan, Philippines, Borneo, Mentawai Islands, Africa, North America, South America, Mesoamerica, Europe, Japan, Cambodia, New Zealand and Micronesia. Despite some taboos surrounding tattooing, the art continues to be popular in many parts of the world.
Tattooing has been a Eurasian practice at least since around Neolithic times. Ötzi the Iceman, dating from the fourth to fifth millennium BC, was found in the Ötz valley in the Alps and had approximately 57 carbon tattoos consisting of simple dots and lines on his lower spine, behind his left knee, and on his right ankle. These tattoos were thought to be a form of healing because of their placement which resembles acupuncture. Other mummies bearing tattoos and dating from the end of the second millennium BC have been discovered, such as the Mummy of Amunet from Ancient Egypt and the mummies at Pazyryk on the Ukok Plateau.
Pre-Christian Germanic, Celtic and other central and northern European tribes were often heavily tattooed, according to surviving accounts. The Picts were famously tattooed (or scarified) with elaborate dark blue woad (or possibly copper for the blue tone) designs. Julius Caesar described these tattoos in Book V of his Gallic Wars (54 BC).
Tattooing in Japan is thought to go back to the Paleolithic era, some ten thousand years ago. Various other cultures have had their own tattoo traditions, ranging from rubbing cuts and other wounds with ashes, to hand-pricking the skin to insert dyes.
Tattooing in the Western world today has its origins in Polynesia, and in the discovery of tatau by eighteenth century explorers. The Polynesian practice became popular among European sailors, before spreading to Western societies generally.
Body piercing, a form of body modification, is the practice of puncturing or cutting a part of the human body, creating an opening in which jewellery may be worn. The word piercing can refer to the act or practice of body piercing, or to an opening in the body created by this act or practice. While the history of body piercing is obscured by a lack of scholarly reference and popular misinformation, ample evidence exists to document that it has been practiced in various forms by both sexes since ancient times throughout the world.
Ear piercing and nose piercing have been particularly widespread and are well represented in historical records and among grave goods. The oldest mummified remains ever discovered were sporting earrings, attesting to the existence of the practice more than 5,000 years ago. Nose piercing is documented as far back as 1500 BC. Piercings of these types have been documented globally, while lip and tongue piercings were historically found in African and American tribal cultures. Nipple and genital piercing have also been practiced by various cultures, with nipple piercing dating back at least to Ancient Rome while genital piercing is described in Ancient India ca. 320 to 550 AD The history of navel piercing is less clear. The practice of body piercing has waxed and waned in Western culture, but it has experienced an increase of popularity since World War II, with sites other than the ears gaining subcultural popularity in the 70s and spreading to mainstream in the 1990s.
The reasons for piercing or not piercing are varied. Some people pierce for religious or spiritual reasons, while others pierce for self-expression, for aesthetic value, for sexual pleasure, to conform to their culture or to rebel against it. Some forms of piercing remain controversial, particularly when applied to youth. The display or placement of piercings have been restricted by schools, employers and religious groups. In spite of the controversy, some people have practiced extreme forms of body piercing, with Guinness bestowing World Records on individuals with hundreds and even thousands of permanent and temporary piercings.
Contemporary body piercing practices emphasize the use of safe
body piercing materials, frequently utilizing specialized tools developed for the purpose. Body piercing is an invasive procedure with some risks, including allergic reaction,
infection, excessive
scarring and unanticipated physical injuries, but such precautions as sanitary piercing procedures and careful aftercare are emphasized to minimize the likelihood of encountering serious problems. The healing time required for a body piercing may vary widely according to placement, from as little as a month for some genital piercings to as much as two full years for the navel.
