In this photo taken on Nov. 24, 2018, Lorenzo, a professional slaughterer, holds a knife which was used to slaughter a pig near Petra, some 60 kilometres from Palma, the capital of Mallorca, Spain. Beneath wintry gray skies on the Mediterranean island of Mallorca, families, friends and neighbors gather for a centuries-old tradition that is not for the faint-hearted: the open-air slaughter of a pig, a custom which due to industrialization has been dying out.
