Sonnet 45

The other two, slight air and purging fire, Are both with thee, where ever I abide; The first my thought, the other my desire, These present-absent with swift motion slide. For when these quicker elements are gone In tender embassy of love to thee, My life being made of four, with two alone Sinks down to death, oppress'd with melancholy; Until live's composition be recured By those swift messengers return'd from thee, Who even but now come back again, assured Of thy fair health, recounting it to me.     This told, I joy, but then no longer glad,     I send them back again and straight grow sad.
