Following his recovery from the Somme and ‘trench fever’ on his return from France in 1916, Tolkien was determined to create an entire mythology for England. He had hinted at this during his undergraduate days at Oxford when he studied and wrote of the Finnish ‘Kalevala’:
“I would that we had more of it left – something of the sort that belonged to the English.”
This idea now grew during his recuperation until it reached ‘epic’ proportions. This is how Tolkien expressed it when recollecting many years later:
“Do not laugh! But once upon a time (my crest has long since fallen), I had a mind to make a body of more or less connected legend, ranging from the large to the cosmogonic to the level of romantic fairy-story – the larger founded on the lesser in contact with the earth, the lesser drawing splendour from the vast backcloths – which I could dedicate simply: to England, to my country. “
