Dr. Faustus - Christopher Marlowe

shall be? Divinity, adieu! These metaphysics of magicians, And necromantic books are heavenly; Lines, circles, scenes, letters, and characters; Ay, these are those that Faustus most desires. O, what a world of profit and delight, Of power, of honour, and omnipotence, Is promis'd to the studious artizan! All things that move between the quiet poles Shall be at my command: emperors and kings Are but obeyed in their several provinces; But his dominion that exceeds in this, Stretcheth as far as doth the mind of man; A sound magician is a demigod: Here tire, my brains, to gain a deity.
