Oedipus at Colonus (Ismene)

Ismene says

The toil and trouble, father, that I bore
To find thy lodging-place and how thou faredst,
I spare thee; surely ’twere a double pain
To suffer, first in act and then in telling;
‘Tis the misfortune of thine ill-starred sons
I come to tell thee. At the first they willed
To leave the throne to Creon, minded well
Thus to remove the inveterate curse of old,
A canker that infected all thy race.
But now some god and an infatuate soul
Have stirred betwixt them a mad rivalry
To grasp at sovereignty and kingly power.
Today the hot-branded youth, the younger born,
Is keeping Polyneices from the throne,
His elder, and has thrust him from the land.
The banished brother (so all Thebes reports)
Fled to the vale of Argos, and help
Of new alliance there and friends in arms,
Swears he will stablish Argos straight as lord
Of the Cadmeian land, or, if he fail,
Exalt the victor to the stars of heaven.
This is no empty tale, but deadly truth,
My father; and how long thy agony,
Ere the gods pity thee, I cannot tell.
