I soon as I saw the title, I figured it was synchronistically relevant. St. Peter has been in the sync-stream of late, particularly in his role as "first pope." He went by two different names, Simon and Peter, the latter meaning "stone." The name Garfunkel ultimately derives from the Latin carbunculus, meaning "reddish, bright kind of precious stone, probably comprising the ruby, carbuncle, hyacinth, garnet." Catholics consider Peter to have been the first pontiff, a title which literally means "bridge-maker." So when Simon and Garfunkel sing about a bridge, that seems likely to have something to do with Peter.
Furthermore, Peter has been associated recently with the title character of the Yeats poem "The Song of Wandering Aengus," in which Aengus pursues a "glimmering girl." I figured this tied in with the "silver girl" in "Bridge over Troubled Water," and I saw that Emily was even wearing a glimmering silver dress to sing it, as if in costume as the glimmering/silver girl herself.
When I played the Emily Linge video, though, I found that she had changed the lyrics -- something she never does! -- and replaced "silver girl" with "children." Now this is unacceptable. Children don't need a bridge over troubled water, nor do they need to sail. When the water is troubled, they wade.
Since Emily had dropped the ball on the "silver girl" bit, I decided to listen to the original. When I put bridge over troubled water in the search box, though, what came up was another Emily Linge cover of the same song, uploaded just a month ago. She's wearing the same silver dress, and this time she gets the lyrics right:
A few hours after writing the above, mentioning three different ways of crossing "troubled water" -- sailing, wading, and using a bridge -- I read this in Louise Varèse's English translation of Arthur Rimbaud's A Season in Hell:
Jesus walked on the troubled waters. The lantern showed him to us, erect, white, with long brown hair, on the flank of an emerald wave.
Yet another way of crossing troubled water! And of course, Jesus was one of two people to walk on water, the other being Peter. The "emerald wave" also syncs with one of Ramer's recurring dreams in The Notion Club Papers:
There is a Green Wave, whitecrested, fluted and scallop-shaped but vast, towering above green fields, often with a wood of trees, too; that has constantly appeared.
This is presumably a vision of the destruction of Númenor, which happened in the reign of its last king, Ar-Pharazôn -- whom William Wright identifies with Peter.
