The night has a thousand eyes,
And the day but one;
Yet the light of the bright world dies
With the dying sun.
This can be interpreted as referring to the stars in the  night  sky, reflections of the sun’s light when it is on the opposite hemisphere. They are  eyes  because they are how we would see, given that  his context was the 19th century  without light pollution from street lights. Currently, it is estimated that our universe has anything from  400 billion stars to a  septillion  The scientists of those times could have recorded 9,000 stars, therefore describing the number as a  thousand  is a definitely quasi-quantifiable statement.
