"Once Polichinelo" is a solo show by a mask-maker-actor who exhibits and experiments with his own masks with the audience, in order to find the one that will accompany him, that will partner with him from then on. It brings together elements from very different contextual universes, with their own dynamics, rules and principles, to become a syncretic object around the mythical Commedia dell'Arte character, Polichinelo. The mask maker's workshop, the room where a lecture is taking place, the rehearsal space where the characters are prepared or explored and the theatre itself where, from a mobilisation around a total representation, endless unfoldings are created for the field of fictional representation. On the table, a lot of masks have been pointed in Polichinelo's direction, from a proposal relating to his remote (and controversial) descent from the Atelian farces (4th century BC), through the Commedia dell'Arte and the Clown (19th century), to the present day, proposing a surprising contemporary Polichinelo. This is a narrative sequence that inevitably runs through the history of theatre in the West.
