AIR, one of the four Elements, is assigned to Urizen. It is materialized as Urizen’s son Thiriel, the first to appear, “astonish’d at his own existence, like a man from a cloud born” (Ur 23:12). Once Blake seems to touch upon the occult theory, which he could have found in Agrippa or Paracelsus, that nothing is ever lost but is preserved in the Air. “Hast thou forgot that the air listens thro’ all its districts, telling the subtlest thoughts shut up from light in chambers of the Moon?” (FZ vii b:242). Even the subtlest thoughts of love are preserved.
