Sonnet 129
Sonnet 129 is one of Shakespeare's most famous sonnets and centers on the idea of the human mind and its primal urges. The sonnet consists of an unknown narrator having an internal mediation with himself about his sexuality; he fears it and harvests feelings of self-disgust for having such desires. "Omne animal post coitum triste est" is a Latin saying that is often quoted in association to sonnet 129. The phrase literally translates into "after sex, every animal is sad." That is the message the sonnet conveys. Shakespeare builds up the sonnet with imagery and desire, and ends it with the feeling of being a victim to lust, as well as the feelings of defeat and disappointment that ensue after the act is done and the desire is no longer there. "Sonnet 129 fixes and deprecates lust with...murderous precision" and Shakespeare leaves us questioning our own primal urges.
