Impotence > "Lack of Self-restraint"; "Violent Passion" (obsolete meanings of this word) her > [was her]

9 But the other was Impatience, armed with raging flame.

211.24

Soone as the Carle from farre the Prince espyde,
2 Glistring in armes and warlike ornament,
His Beast he felly prickt on either syde,
4 And his mischieuous bow full readie bent,
With which at him a cruell shaft he sent:
6 But he was warie, and it warded well
Vpon his shield, that it no further went,
8 But to the ground the idle quarrell fell:
Then he another and another did expell.

1 Soon as the carl from far the prince espied,

Soon > [As soon] carl > villain, churl

2 Glistering in arms and warlike ornament,

arms > {Arms and armour}
