Summary of sonnet 18

Here the theme of the ravages of time again predominates; we see it especially in line 7, where the poet speaks of the inevitable mortality of beauty: "And every fair from fair sometime declines." But the fair lord's is of another sort, for it "shall not fade" - the poet is eternalizing the fair lord's beauty in his verse, in these "eternal lines." Note the financial imagery ("summer's lease") and the use of anaphora (the repetition of opening words) in lines 6-7, 10-11, and 13-14. Also note that May (line 3) was an early summer month in Shakespeare's time, because England did not adopt the Gregorian calendar until 1752.
