"As the glossaries lengthen, as the footnotes become more elementary and didactic, the poem, the epic, the drama, move out of balance on the actual page. As even the more rudimentary of mythological, religious or historical references, which form the grammar of Western literature, have to be elucidated, the lines of Spenser, of Pope, of Shelley or of Sweeney Among the Nightingales, blur away from immediacy.
