Is it a flower or a creature? Is it perhaps a intermediate being between flora and fauna? Is a spiritual being, a lotus flower bloomed out of deep meditation?
[EDIT: I traded the original for a better illuminated version.]
The flowers whose purple and translucid bowls
Stand ever mantling with aëreal dew,
The drink of spirits: and it circles round,
Like the soft waving wings of noonday dreams,
Inspiring calm and happy thoughts, like mine,
Now thou art thus restored. This cave is thine.
[A Spirit rises in the likeness of a winged child]
This is my torch-bearer
Percy Bysshe Shelley, "Prometheus Unbound", Scene III (3.3.142).
