Banished by Eliza as Sylvia

Val.  And why not death rather than living torment?
To die is to be banish’d from myself;	164
And Silvia is myself: banish’d from her
Is self from self,—a deadly banishment!
What light is light, if Silvia be not seen?
What joy is joy, if Silvia be not by?	168
Unless it be to think that she is by
And feed upon the shadow of perfection.
Except I be by Silvia in the night,
There is no music in the nightingale;	172
Unless I look on Silvia in the day,
There is no day for me to look upon.
She is my essence; and I leave to be,
If I be not by her fair influence	176
Foster’d, illumin’d, cherish’d, kept alive.  De Vere was banished from Eliza’s presence for his affair with Anne Vavasour.  In the play we have two sides of his personality, two gentlemen but one Vere: The Two Gentlemen of Verona.
