 "The Shadow of the Glen", under the title "In the Shadow of the Glen", formed part of the bill for the opening run of the Abbey Theatre from 27 December 1904 to 3 January 1905.Both plays were based on stories that Synge had collected in the Aran Islands, and Synge relied on props from the Aran Islands to help set the stage for each of them.He also relied on Hiberno-English, the English dialect of Ireland, to reinforce its usefulness as a literary language, partly because he believed that the Irish language could not survive.
