The title of the performance is drawn from the 1955 first publication of a “complete” edition of Dickinson’s poems, edited by Thomas H. Johnson. In what Johnson called a “subject index” he grouped the poems under headers like “Death,” or “Mountains,” presumably so that if you were looking for a half-remembered Dickinson poem you could narrow down your search to likely candidates. From when I first encountered this index, I was fascinated by its quixotic efforts.
