Analysis of Farewell, Fair Armida. A Song

Farewell, fair Armida, my joy and my grief!
In vain I have loved you, and hope no relief;
Undone by your virtue, too strict and severe,
Your eyes gave me love, and you gave me despair:
Now called by my honour, I seek with content
The fate which in pity you would not prevent:
To languish in love were to find, by delay,
A death that's more welcome the speediest way.
On seas and in battles, in bullets and fire,
The danger is less than in hopeless desire;
My death's wound you give me, though far off I bear
My fall from your sight—not to cost you a tear:
But if the kind flood on a wave should convey,
And under your window my body should lay,
The wound on my breast when you happen to see,
You'll say with a sigh—it was given by me.
