John Skelton Quote

Steadfast of thought,
Well made, well wrought,
Far may be sought,
Ere that ye can find
So courteous, so kind
As merry Margaret,
This midsummer flower,
Gentle as falcon
Or hawk of the tower.

To Mistress Margaret Hussey, lines 26-34, probably published c. 1511, reported in Bartlett's Familiar Quotations, 10th ed. (1919).
