Marlowe took it and turned it to his own uses.

There is in his writings a lust of power, "a hunger and thirst after unrighteousness," a glow of the imagination unhallowed by anything but its own energy which is in the spirit of the time.

In _Tamburlaine_ it is the power of conquest, stirred by and reflecting, as we have seen, the great deeds of his day.

In _Dr.Faustus_ it is the pride of will and eagerness of curiosity.

Faustus is devoured by a tormenting desire to enlarge his knowledge to the utmost bounds of nature and art and to extend his power with his knowledge.
