"Night and her ugly subjects thou dost fright,
And Sleep, the lazy owl of night;
Asham'd and fearful to appear,
They screen their horrid shapes with the black hemisphere."
Wakefield cites Milton, _Hymn on Nativity_, 233 foll.: "The flocking
shadows pale," etc. See also _P. R._ iv. 419-431.

night-birds tell."
