Cædmon, an English poet of the 7th century, the fragment of a hymn by whom, preserved by Bede, is the oldest specimen extant of English poetry; wrote a poem on the beginning of things at the call of a voice from heaven, saying as he slept, “Cædmon, come sing me some song”; and thereupon he began to sing, as Stopford Brooke reports, the story of Genesis and Exodus, many other tales in the sacred Scriptures, and the story of Christ and the Apostles, and of heaven and hell to come.
