ARKAS
Priestess, with speed conclude the sacrifice!
Impatiently the king and people wait.
IPHIGENIA
I had perform'd my duty and thy will,
Had not an unforeseen impediment
The execution of my purpose thwarted.
ARKAS
What is it that obstructs the king's commands?
IPHIGENIA
Chance, which from mortals will not brook control.
ARKAS
Possess me with the reason, that with speed
I may inform the king, who hath decreed
The death of both.
