Jet of Blood (Jet de Sang), also known as Spurt of Blood, is an extremely short play by the French theatre practitioner, Antonin Artaud, who was also the founder of the "Theatre of Cruelty" movement. Jet of Blood was completed in Paris, on January 17, 1925, perhaps in its entirety on that day alone. The original title was Jet de Sang ou la Boule de Verre, but the second half of the title was dropped prior to the first publication and production of the work.[1]
