Thou shalt be made a king and reign with me,
Keeping in iron cages emperors.
If thou exceed thy elder brothers' worth,
And shine in complete virtue more than they,
Thou shalt be king before them, and thy seed
Shall issue crowned from their mother's womb.

CELEBINUS. Yes, father; you shall see me, if I live,
Have under me as many kings as you,
And march with such a multitude of men
As all the world shall<38> tremble at their view.

TAMBURLAINE. These words assure me, boy, thou art my son.
When I am old and cannot manage arms,
Be thou the scourge and terror of the world.

AMYRAS. Why may not I, my lord, as well as he,
Be term'd the scourge and terror of<39> the world?

TAMBURLAINE. Be all a scourge and terror to<40> the world,
Or else you are not sons of Tamburlaine.

CALYPHAS. But, while my brothers follow arms, my lord,
Let me accompany my gracious mother:
They are enough to conquer all the world,
And you have won enough for me to keep.

TAMBURLAINE. Bastardly boy, sprung<41> from some coward's loins,
And not the issue of great Tamburlaine!
Of all the provinces I have subdu'd
