Sunne, thou governest the world, thou treadest downe the power of hell: By thy meane the times returne, the Planets rejoyce, the Elements serve: at thy commandment the winds do blow, the clouds increase, the seeds prosper, and the fruits prevaile, the birds of the aire, the beasts of the hill, the serpents of the den, and the fishes of the sea, do tremble at thy majesty, but my spirit is not able to give thee sufficient praise, my patrimonie is unable to satisfie thy sacrifice, my voice hath no power to utter that which I thinke, no if I had a thousand mouths and so many tongues: Howbeit as a good religious person, and according to my estate, I will alwaies keepe thee in remembrance and close thee within my breast.
