But still twixt feare and hope amazd does sit,

Are wonne with pitty and vnwonted ruth,

Doe kisse her feete, and fawne on her with count'nance faine.

Their harts she ghesseth by their humble guise,
2 And yieldes her to extremitie of time;
So from the ground she fearelesse doth arise,
4 And walketh forth without suspect of crime:
They all as glad, as birdes of ioyous Prime,

Shouting, and singing all a shepheards ryme,
8 And with greene braunches strowing all the ground,
Do worship her, as Queene, with oliue girlond cround.
