The earliest literature was oral. It is the human voice that transmits myths, stories, songs, and humanity’s memories. Bards, griots, minstrels, troubadours, and bertsolaris (versificators) were later joined by rappers, slammers, and artists of the Spoken Word. The oral word, recited, sung, and brought up to date, is one of the identifying features of Kosmopolis, this time in the form of an “underwater rhapsody”, in which new artists of the oral tradition offer an event that is prodigious in styles and languages.
