Ocumicho is a Purépecha town of the Mexican state of Michoacán in which it is said that "the devil sticks his tail everywhere", that he is a great metiche that walks from house to house, in the city and on the hill, murmuring temptations and weaving entanglements among the people of the world.. This is also how the devils, saints and mud sirens who are modeled in this place walk, articulating agents of ideas and relationships that reach the most unexpected hiding places. The title of this book refers to those trips made by the pieces created by the potters of Ocumicho, to the analysis of the social life of a type of works that move between the creativity of the artists, the stories and images that inspire them, the stoves of their houses, the floor of the tianguis, shelves of tourists and intellectuals, pages of books, the works of other artists, public policies, markets, international galleries and ethnographic museums. We will focus in these pages on a type of sculptures in polychrome clay whose "tails" leave a trace that allows us to understand the complexity of the phenomenon studied.
