in 1968, when he was 26 years old, Michel Tremblay brutally gave access to the Quebec theatre to modernity when his room was depicted in Montreal. The sisters, written entirely in joual, the vernacular talk of the east. Since that date, the majority of his works, from the cycle of sisters to the coins of the 1990s and 2000s, from the Roman cycle of the Chronics of the Plateau-Mont-Royal to that of Jean-Marc, its double diploma, have all been markers.
