To dreadfull shapes he did himselfe transforme,
2 Now like a Gyant, now like to a feend,
Then like a Centaure, then like to a storme,
4 Raging within the waues: thereby he weend
Her will to win vnto his wished +end+.
6 But when with feare, nor fauour, nor with all
He else could doe, he saw himselfe esteemd,
8 Downe in a Dongeon deepe he let her fall,
And threatned there to make her his eternall thrall.
