Isabella Augusta, Lady Gregory was an Irish dramatist, folklorist and theatre manager. With William Butler Yeats and Edward Martyn, she co-founded the Irish Literary Theatre and the Abbey Theatre, and wrote numerous short works for both companies. Lady Gregory produced a number of books of retellings of stories taken from Irish mythology. Born into a class that identified closely with British rule, she turned against it. Her conversion to cultural nationalism, as evidenced by her writings, was emblematic of many of the political struggles to occur in Ireland during her lifetime.
