Thus fairely she attempered her feast,
2 And pleasd them all with meete satietie,
At last when lust of meat and drinke was ceast,
4 She Guyon deare besought of curtesie,
To tell from whence he came through ieopardie,
6 And whither now on new aduenture bound.
Who with bold grace, and comely grauitie,
8 Drawing to him the eyes of all around,
From lofty siege began these words aloud to sound.
