Who is Silvia? lyrics

Who is Silvia? what is she
That all our swains commend her?
Holy, fair and wise is she;
The heaven such grace did lend her
That she might admired be
Is she kind as she is fair?
For beauty lives with kindness
Love doth to her eyes repair
To help him of his blindness
And, being help'd, inhabits there
Then to Silvia let us sing
That Silvia is excelling;
She excels each mortal thing
Upon the dull earth dwelling:
To her let us garlands bring
