Of all the branches

Why do I start thinking of the Dream of Rhonabwy, which is perhaps best known for the exhortation of its ending, and misremember it to boot?

And this tale is called the Dream of Rhonabwy. And this is the reason that no one knows the dream without a book, neither bard not gifted seer; because of the various colours that were upon the horses, and the many wondrous colours of the arms and of the panoply, and of the precious scarfs, and of the virtue-bearing stones.
