Many things are unknown. Once - it was about six or seven months ago - I saw a bright yellow speck floating on a gentle Tide beneath the Fourth Western Hall. Not understanding what it could be, I waded out into the Waters and caught it. It was a leaf, very beautiful, with two sides curving to a point at each end. Of course it is possible that it was part of a type of sea vegetation that I have never seen, but I am doubtful. The texture seemed wrong. Its surface repelled Water, like something meant to live in Air.
-- Piranesi, Susanna Clarke
