But here, sir, it behoves me shift my ground,
Like him that makes the           viol ring,
Who often changes chord and varies sound,
And now a graver strikes, now sharper string:
Thus I: -- who did to good Rinaldo bound
My tale, Angelica remembering;
Late left, where saved from him by hasty flight,
She had encountered with an anchorite.
