The Teatro Ulises (literally Odysseus theater) was an experimental theater, located in the calle de Mesones 42 of Mexico City, that was established around 1927[1]/1928[2] by Antonieta Rivas Mercado, daughter of the architect Antonio Rivas Mercado, and further members of the group Los Contemporáneos. The small theater with about 50 seats[3] only existed for a few months until 1929, but influenced modern Mexican theater fundamentally.[4]
