The sooner will his race be run, And nearer he's to setting. (7-8)
The progress of the sun is meant to correspond to a human being's
progress through life. The "setting" is supposed to represent dying, but
the image of the setting sun doesn't quite suggest death strongly
enough. There's something graceful about it, an aspect captured in the
word "setting," which suggests a temporary stasis, not necessarily
something as permanent as death.
