Santiago Sierra’s art often includes marginalized groups of people such as immigrants, sex workers, asylum seekers, and people with low incomes. The artist usually hires them to do menial and uncomfortable tasks like sitting in a box during an exhibition for several hours, getting their naturally dark hair dyed blond, or having a line tattooed on their back for payment. Santiago Sierra’s work commonly references topics like social inequality, capitalism, morality, and labour. The work shown above by Sierra inspired me more because I was a professional tattoo artist at the time and the visuals made me question the nature of skin, and it’s role in most societies.
