5 Who, when her eyes she on the dwarf had set, 6 And saw the signs that deadly tidings spoke, 7 Fell to ground for sorrowful regret;

8 And lively breath her sad breast did forsake,

9 Yet might her piteous heart be seen to pant and quake.

107.21

The messenger of so vnhappie newes,
2 Would faine haue dyde: dead was his hart within,
Yet outwardly some little comfort shewes:
4 At last recouering hart, he does begin
To rub her temples, and to chaufe her chin,
6 And euery tender part does tosse and turne:
So hardly he the flitted life does win,
8 Vnto her natiue prison to retourne:
Then gins her grieued ghost thus to lament and mourne.
