Wherefore I wish all Christians to take example by this wicked doctor, and to be comforted in Christ, concerning themselves with that vocation whereunto it has pleased God to call them, and not so esteem the vain delights of this life as did this unhappy Faustus in giving his soul to the devil: and to confirm it the more assuredly, he took a small penknife, and pricked a vein in his left hand, and for certainty thereupon were seen on his hand these words written, as if they had been written in his own blood, O HOMO FUGE; whereat the spirit vanished, but Faustus continued in his damnable mind. CHAPTER VI. _How Dr. Faustus set his Blood in a Saucer on warm Ashes, and writ as followeth:_ I, John Faustus, _doctor, do openly acknowledge with mine own hand, to the great force and strengthening of this letter, that since I began to study, and speculate the course and nature of the elements, I have not found, through the gift that is given me from above, any such learning and wisdom that can bring me to my desire and for that I find that men are unable to instruct me any farther in the matter; now have I, Dr. Faustus, to the hellish prince of Orient, and his messenger Mephistophiles, given both body and soul, upon such conditions, that they shall learn me, and fulfil my desires in all things, as they have promised and vowed unto me, with due obedience unto me, according to the articles mentioned between us._ Farther, I do covenant and grant _with them by these presents, that at the end of twenty-four years next ensuing, the date of this present letter, they being expired, and I in the mean time, during the said years, be served of them at my will, they accomplishing my desires to the full in all points as we are agreed: that then I give to them all power to do with me at their pleasure, to rule, to send, fetch or carry me or mine, be it either body, soul, flesh, blood or goods, into their habitation, be it wheresoever: and hereupon I defy God and his Christ, all the Host of Heaven, and all living creatures that bear the shape of God; yea, all that live: And again I say it, and it shall be so, and to the more strengthening of this writing, I have written it with my own hand and blood, being in perfect memory: and hereupon I subscribe to it with my name and title, calling all the infernal, middle, and supreme powers to witness of this my letter and subscription._ John Faustus. _Approved in the elements, and the spiritual doctor._ CHAPTER VII. _How Mephistophiles came for his Writing, and in what manner he appeared, and his Sights he showed him; and how he caused him to keep a Copy of his own Writing._
