Larval mask 14 has been described as an owl, a fly, a bug and an overly surprised bird. The larval masks are in their basic stage of development and celebrate a child like innocence and fantasy play.
Their place in the training arch inspires an understanding of the spontaneity and the mechanics of play as concerns the craft of acting. They are part of the actor training system invented and disseminated by Jacques Lecoq.
The larval masks are also referred to as Basel masks because of their origin in the celebration of Carnival in Basel, Switzerland.
