One can watch a number of the silent films mentioned in Art of the Moving Picture by Vachel Lindsay; thanks to the Internet Archives.Here are the links to enable your study. I recommend watching the movies with your favorite electronic track (e.g. something from EXFM).
D.W. Griffith's: Birth of a Nation ; Enoch Arden
Thomas H. Ince: Grandad; The Return of Draw Egan
Giovanni Pastrone: Cabiria
