Nothing in eternity, a wandering ring, nothing in time, circle, pretence and vertigo, nothing in death, arteries of water and void. The flower of oblivion is uprooted and a lament sounds in the mist, a hawk flies over the blue meadow, in front of the immutable wall of remembrance and the iridescent air pulls out a sordid song.
