The Ascent of F6: A Tragedy in Two Acts, by W. H. Auden and Christopher Isherwood, was the second and most successful play in the Auden-Isherwood collaboration, first published in 1936. It was a major contribution to English poetic drama in the 1930s. It has been seen as a parable about will, leadership and the nature of power: matters of increasing concern in Europe as that decade progressed. Source: Wikipedia (en)
