El cerco de Numancia
The play is also known as The Numancia, Comedy of the siege of Numancia, The destruction of Numancia and Tragedy of Numancia. Two handwritten copies of the play have survived.  One copy is in the National Library of Spain which is an actor's script from the 17th century. Another copy, the codex Sancho Rayón, is held by the Hispanic Society of America. This copy was made by Antonio of Sancha in 1784, with modern spelling, together with another play, the Trip of the Parnaso. Both copies are believed to be based closely on the original, although the modern editors prefer to use The Numancia from the manuscript Sancho Rayón.
