The other two, slight air and purging fire,
Are both with thee, wherever I abide;
The first my thought, the other my desire,
These present-absent with swift motion slide.
For when these quicker elements are gone 5
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 life's composition be recured
By those swift messengers return'd from thee, 10
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.
