Bird that art Singing on Ebro's side

Bird that art singing on Ebro's side!
Where myrtle shadows make dim the tide,
Doth sorrow dwell midst the leaves with thee?
Doth song avail thy full heart to free?
Bird of the midnight's purple sky!
Teach me the spell of thy melody.
Bird! is it blighted affection's pain
Whence the sad sweetness flows through thy strain?
And is the wound of that arrow stilled
When thy lone music the leaves hath filled?
Bird of the midnight's purple sky!
Teach me the spell of thy melody.
