A journey through solitude in art, seen in its various forms: from Schubert's music to Mirò's paintings, passing through cave paintings, waiting to be discovered. A journey that, from Friedrich's paintings, leads to an interview with a hermit to understand his choice of solitude; and that, through the analysis of a psychologist, leads to an interpretation of the works of Hopper and Giacometti. The exhibition concludes with the experiment of freeing a painting by Masriera from the solitude of a museum's storage rooms and displaying it in a public square; and an interview with a former death row inmate, to understand the hopeless loneliness of those who live in that condition.
