Tiberio Fiorilli, also spelled Fiorillo and Fiurelli (November 9, 1608 – December 7, 1694) was an Italian actor of commedia dell'arte known for developing the role of Scaramouche. He was especially popular in France, where he was the director of the troupe of the Comédie-Italienne, which shared with the troupe of his friend Molière at the theatre of the Petit-Bourbon, and the theatre of the Palais-Royal.
He was born in Naples, but left Italy around 1640 for unknown reasons, perhaps simply while following a troupe of actors, or to flee a political intrigue. He arrived in France under the reign of Louis XIII. His acting pleased the queen, which enabled him to attend the court.
It is said that one day, when the two-year-old Dauphin cried (the future Louis XIV), Fiorilli, as Scaramouche, made any possible sound to comfort him. He achieved this task with grimaces and tomfoolery; consequently, the Dauphin had "a need, that he had at the time, the hands and the dress of Scaramouche". Fiorilli was then ordered to visit the court every night to amuse the Dauphin, which helped the Scaramouche character become a stock figure in the theatre of the time. The character of Scaramouche became a standard role thereafter of the commedia dell'arte.
Fiorilli's style differed from other commedia dell'arte players. He abandoned the mask and used the expressiveness of his face to enhance the comedy. His large eyes and eyebrows and long nose contributed to this effect, and he wore moustaches that framed the corners of his mouth and a thin, short goatee. These practices influenced Molière, and by most accounts the two actors developed a close relationship during the years they shared the same theaters. Some critics went so far as to accuse Molière of being Scaramouche's ape. One engraving shows Molière mimicking Scaramouche's grimaces with the help of a mirror.
