Who Is Sylvia?

Who is Sylvia? What is she, that all our swains commend her? Holy, fair and wise is she The Heav'ns such grace did lend her, That adored she might be, That adored she might be. Is she kind as she is fair? For beauty lives with kindness; To her eyes doth love repair To help him of his blindness; And being help'd in habits there, And being help'd in habits there. Then to Sylvia let us sing, That Sylvia is excelling; She excells each mortal thing Upon the dull Earth dwelling; To her garlands let us bring, To her garlands let us bring.
