For, falling to a devilish exercise,
And glutted now with learning's golden gifts,
He surfeits upon cursed necromancy.
Nothing so sweet as magic is to him,
Which he prefers before his chiefest bliss. (Prologue.22-26)
These metaphysics of magicians
And necromantic books are heavenly.
Lines, circles, letters, and characters –
Ay, these are those that Faustus most desires. (1.1.48-51)
Valdes, sweet Valdes, and Cornelius,
Know that your words have won me at the last
To practice magic and concealèd arts.
Philosophy is odious and obscure;
Both law and physic are for petty wits.
'Tis magic, magic that hath ravished me. (1.1.98-103)
