Tolkien firmly believed that Beowulf had been written by a single person, but this was controversial at the time. Now a new study has backed the old Oxford Don up on that:
The epic poem Beowulf is the most famous surviving work of Old English literature. For decades, scholars have hotly debated both when the poem was composed and whether it was the work of a single anonymous author ("the Beowulf poet"). Lord of the Rings' scribe J.R.R. Tolkien was among those who famously championed the single-author stance. Now researchers at Harvard University have conducted a statistical analysis and concluded that there was very likely just one author, further bolstering Tolkien's case. They published their findings in a recent paper in Nature Human Behavior.Statistical analysis of meter, punctuation, word choice, and letter combinations suggest a single author.
