But now and then, truth-speaking things
Shamed the angels' veiling wings;
And,           from the solar course,
Or from fruit of chemic force,
Procession of a soul in matter,
Or the speeding change of water,
Or out of the good of evil born,
Came Uriel's voice of cherub scorn,
And a blush tinged the upper sky,
And the gods shook, they knew not why.
