This is a very very beautiful and one of the stronger sonnets of Shakespeare. I have always loved this one, so much so that it's hardly possible for me to ever forget it.I hope you like it:

Since brass, nor stone, nor earth, nor boundless sea, but sad mortality, o'ersways their power, How with this rage shall beauty hold its plea, whose action is no stronger than a flower? O!How shall summer's honey-breath hold out, Against the wreckful seige of battering days, When rocks impregnable are not so stout, nor gates of steel so strong but time decays? O fearful meditation! Where, alack, Shall Time's best jewel from Time's chest lie hid? Or what strong hand can hold its swift foot back? Or who his spoil of beauty can forbid? O! None, unless this miracle have might, That in black ink, my love may still shine bright!
