Lucifer Character Analysis

I am a servant to great Lucifer,
And may not follow thee without his leave;
No more than he commands must we perform. (40-42)

Go bear these tidings to great Lucifer,
Seeing Faustus hath incurred eternal death
By desperate thoughts against Jove's deity:
Say, he surrenders up to him his soul
So he will spare him four and twenty years,
Letting him live in all voluptuousness,
Having thee ever to attend on me,
To give me whatsoever I ask,
To tell me whatsoever I demand,
To slay mine enemies, and aid my friends,
And always be obedient to my will. (87-89)

But Faustus, thou must bequeath it solemnly,
And write a deed of gift with thine own blood,
For that security craves great Lucifer. (34-36)

Sweet Mephastophilis, entreat thy lord
To pardon my unjust presumption;
And with my blood again I will confirm
My former vow I made to Lucifer. (60-63)

One thing, good servant, let me crave of thee,
To glut the longing of my heart's desire:
That I might have unto my paramour
That heavenly Helen which I saw of late,
Whose sweet embracings may extinguish clean
These thoughts that do dissuade me from my vow:
And keep mine oath I made to Lucifer. (72-78)

Ugly hell gape not! Come not, Lucifer!
I'll burn my books—ah, Mephastophilis! (112-113)
