In Robert Herrick's "To the Virgins," the second stanza finds the speaker waxing redundant as he refers to the sun both metaphorically and literally: "The glorious lamp of heaven, the sun." It is obvious that the redundancy is committed for the purpose of adhering a rime onto the third line: "The sooner will his race be run." The speaker thus wants to compare the virgin's run through life to the sun's run through the heavens during the day. The higher the sun moves the closer he is to setting. And while in reality there is no such thing as "setting" for the sun, the beauty of the poor little virgins will, in fact, run its course and set and then they are screwed (ironic pun intended)!
