The "Ostana Prize: Writings in Mothers Languages" is a celebration of the cultural diversity of humanity. The common goal is to listen to the sound of indigenous uncommon languages that nevertheless want to live, and through them discover the past and present stories of the peoples who speak them. The native languages represented at the Premio Ostana have the common characteristic of being unfortunately relegated to a condition of unequal opportunities compared to the dominant language of their reference states, and for this reason each of them incarnates a specificity and biodiversity to defend, preserve, protect and describe. While it is true that each linguistic-cultural area has its own specifics, it is equally true that problems and difficulties are often common, and strategies and plans can be common to deal with. Born with the desire to know and make known writers, filmmakers, musicians from different parts of the planet, it has become a formidable opportunity to meet and exchange experiences for dozens of authors who in Europe, Africa, Asia, the Americas and in Oceania illustrate and make the language of their community alive with their creative work.
