When we can't understand the science behind something in this world, we make up mythological entities that we can relate to. We personify the forces of nature that mystify us, using our boundless imaginations to comfort us and make us feel like we have some control over these things that are much bigger than we are.
For this new-married man approaching here,Whose salt imagination yet hath wrong'dYour well defended honour, you must pardonFor Mariana's sake: but as he adjudged your brother,--Being criminal, in double violationOf sacred chastity and of promise-breachThereon dependent, for your brother's life,--The very mercy of the law cries outMost audible, even from his proper tongue,'An Angelo for Claudio, death for death!'Haste still pays haste, and leisure answers leisure;Like doth quit like, and MEASURE still FOR MEASURE
To die, is to be banish'd from myself; And Silvia is myself: banish'd from her, Is self from self: a deadly banishment! What light is light, if Silvia be not seen? What joy is joy, if Silvia be not by? Unless it be to think that she is by, And feed upon the shadow of perfection.Except I be by Silvia in the night, There is no music in the nightingale; Unless I look on Silvia in the day, There is no day for me to look upon; She is my essence, and I leave to be, If I be not by her fair influence Foster'd, illumin'd, cherish'd, kept alive.
