The theme of Sonnet 73 is mortality leading to death; there even seems to be a bit of sadness as the speaker is moving closer to death and warns the listener that he/she will perhaps love/miss them more as they will leave forever. I agree with Greg that the theme ultimately comes across as a universal one, as it is basically one of mortality. Brenda
What an interesting question! I say this because the poem's theme is mortality, and specifically how all who love, no matter how intensely, must die. The idea that this could be anything but universal never occurred to me. That might make me parochial, but I would say Shakespeare is here addressing a sad but universal truth.
