In this video you hear 93-year-old Pope Leo XIII chant Ave Maria in Latin–the oldest known audio recording of a Pope. This recording, made a few months before he died in 1903, is superimposed over the very first film footage of a Pope in existence. The film itself was made in 1896, it begins without sound. In this film you see Pope Leo XIII in 1896 descending from a horse-drawn carriage, removing his galero and glasses (giving them to aides) fixing his hair, receiving homage and giving benediction to the assembled. This segues to another brief footage of him giving benediction in another setting.
