2Dinas Emrys, (the fortress of Ambrose,) a celebrated rock amongst the mountains of Snowdon, is said to be so called from having been the residence of Merddin Emrys, called by the Latins Merlinus Ambrosius, the celebrated prophet and magician: and there, tradition says, he wrote his prophecies concerning the future state of the Britons. There is another curious tradition respecting a large stone, on the ascent of Snowdon, called Maen du yr Arddu, the black stone of Arddu. It is said, that if two persons were to sleep a night on this stone, in the morning one would find himself endowed with the gift of poetry, and the other would become insane.—Williams's Observations on the Snowdon Mountains.
3It is believed amongst the inhabitants of these mountains, that eagles have heretofore bred in the lofty clefts of their rocks. Some wandering ones are still seen at times, though very rarely, amongst the precipices.—Williams’s Observations on the Snowdon Mountains.
