Transporting readers through history, Lars Krutak explores the art and customs of tattooing across numerous ancestral lands, including Africa, the Middle East, the Americas, the Arctic, Oceania, Japan, Southeast Asia, and Siberia. He illustrates how tattoos function as a form of writing that defines and structures community life, performing as rites of passage, symbols of rank, and signs of marital or religious devotion, among other facets of culture. We are introduced to the heavily tattooed Li women of China’s Hainan Island with their elaborate facial and body tattoos, the bold indelible markings of Papua New Guinea’s Indigenous peoples, and innovative cultural tattoo practitioners who are rebuilding a skin-marking legacy for future generations to come.
