1593-1603 by Shakespeare 
Sonnet 78 

1	So oft have I invoked thee for my muse
2	And found such fair assistance in my verse
3	As every alien pen hath got my use,
4	And under thee their poesy disperse.
5	Thine eyes, that taught the dumb on high to sing
6	And heavy ignorance aloft to fly,
7	Have added feathers to the learned’s wing
8	And given grace a double majesty.
9	Yet be most proud of that which I compile,
10	Whose influence is thine and born of thee.
11	In others’ works thou dost but mend the style,
12	And arts with thy sweet graces gracèd be#
13	But thou art all my art, and dost advance
14	As high as learning my rude ignorance.
