In the neighbourhood it is fondly dreamed that this was the tarn into which Arthur had Excalibur cast.
"On one side lay the ocean, and on one
Lay a great water----"
After the sword had been cast in, hither Arthur was carried by Sir Bedivere.
"To left and right
The bare black cliff clang'd round him, as he based
His feet on juts of slippery crag, that rang
Sharp smitten with the dint of armed heels--
And on a sudden, lo! the level lake,
And the long glories of the winter moon."
