As long as skies are blue, and fields are green,
Evening must usher night, night urge the morrow,
Month follow month with woe, and year wake year to sorrow.

The lines use the steady cycles of nature—blue skies, green fields, evening yielding to night, night to morning, months to months—to underscore a bleak counterpoint: human life can feel like an equally inescapable cycle of suffering. By yoking natural recurrence to “woe” and “sorrow,” the speaker suggests that grief is not an aberration but something that returns with the regularity of time itself. The effect is fatalistic and elegiac: the world’s beauty and order do not prevent pain, and may even sharpen it by contrast. Read more broadly, the passage reflects a Romantic preoccupation with transience and the persistence of loss amid nature’s apparent continuity.
