O Nightingale that on yon bloomy Spray a poem by John Milton

O Nightingale that on yon bloomy Spray,
Warbl'st at eve, when all the Woods are still
Thou with fresh hope the Lover's heart dost fill,
While the jolly hours lead on propitious May,
Thy liquid notes that close the eye of Day,
First heard before the shallow Cuckoo's bill
Portend success in love; O if Jove's will
Have linkt that amorous power to thy soft lay,
Now timely sing, ere the rude Bird of Hate
Foretell my hopeless doom in some Grove nigh:
As thou from year to year hath sung too late
For my relief; yet hadst no reason why,
Whether the Muse, or Love call thee his mate,
Both them I serve, and of their train am I.
