Iris.
The cauda pavonis or Tail of the Peacock.
“This is the bird which flies by night without wings, which the early dew of heaven, continually acting by upward and downward ascent and descent, turns into the head of a crow (caput corvi), then into the tail of a peacock, and afterwards it acquires the bright wings of a swan, and lastly an extreme redness, an index of its fiery nature.”
~Theatrum Chemicum
