Between 1971 and 1974, Sony Labou Tansi submits four anticipation plays to the Concours théâtral interafricain : Le Bombardé (1971), Le Ventre (1972), Conscience de tracteur (1973) and La Gueule de rechange (1974). This corpus is based on time projections relatively close to the present tense of writing ; the events of each play, indeed, take place at the end of the 20 th century. To this choice of the late 1990’s must be added a second peculiarity, linked to the issue of « afrotopisme » (Anthony Mangeon, 2022). With different literary devices, these plays evoke the advent of a new humanity, turned towards a future to think and build. The following essay studies the characteristics and the aims of these anticipation plays from an image used in the « Épilogue » of Le Bombardé : in this text, an unquenchable « soif de lendemain » is expressed.
