Antonio Buero Vallejo, Historia de una escalera (1947), El Tragaluz (1967) Spain
Buero Vallejo was one of the foremost dramatists of the Franco era, writing plays that offered subtle criticism of the regime whilst encouraging people to be hopeful about the future.
Fernando Arrabal, Pic-nic (c. 1952)
Another dramatist of the Franco era, but writing in a very different mode. He left Spain for France, seeking greater artistic freedom. Pic-nic is an absurdist play in which a soldier's parents join him on the battlefield for a day out in the country.
Federico García Lorca, La zapatera prodigiosa (1930) Spain (Andalucía)
Undoubtedly the most internationally renowned of Spain's playwrights, Lorca is best known for his rural trilogy. La zapatera prodigiosa is written in the style of a puppet play, and brings together farce with some of the author's most enduring themes.
Jacinto Grau, El señor de Pigmalión (1921) Spain
Inspired by the Greek myth of Pygmalion and Galatea, the play depicts the downfall of a theatre impresario who has created a company of living dolls. Submissive and cowed before their creator at first, the dolls eventually become rebellious.
Lope de Vega, Fuenteovejuna (1619) Spain
A small town rises up against the oppression of a cruel overlord, putting him to death in an act of collective justice. A drama about popular and institutional power, and its uses and abuses, this play has been staged regularly since it was written to express political upheaval and what can happen when a town takes the law into its own hands.
Calderón de la Barca, La vida es sueño (1635) Spain
One of the theatrical masterpieces of the Spanish Golden Age, La vida es sueño is a remarkably modern questioning of reality and perception, free will and destiny. It was performed by a student company, in Spanish with English surtitles, at the Oxford Playhouse in April 2013: http://www.oxfordspanishplay.com/
