Two letters

Jupiter,

             I can see her in the wobble of your gait
             Even when you have her hidden,
             The thing you have,
                                     Captured
                                     Tethered
                                     Taken
             She is not the first,
             But know this
             Every time you tug upon her
             You exert a force upon yourself as well
              And you are starting
                                      To slip

Elara,
             In two parts I entreat you;
             He is not the first
             To use whole planets to hide you
             Please,
             Is it colder there?

                                                                                     -Zeus
