We will talk about a pictorial art that allows the decoration of the human body; that of the tattoo is a tradition that we find far back in time. Through the testimonies of tattoo artists and tattooed subjects, we will tell the value attributed to the art of tattooing in the past, how it has changed over time and its cultural, anthropological, magical-curative and aesthetic value, up to its current dimension. An excursus from the origins to the present day. Religious, therapeutic, noble, punitive, artisans, Camorra, crime and marginalization tattoos, hippies, up to those of sailors. This is revealed as an Italian tradition still largely unknown today, which passes through the meshes of history, from north to south, through wars, professions, religious orders, love, vanity and power. You will discover the power of ink on skin.
