What does Faustus originally ask Mephastophilis to bring him Helen of troy

The Tragical History of Life and Death of Doctor Faustus by Christopher Marlowe tells of a German scholar who got weary of logic, medicine, law and religion. He turns to black magic and strikes up a deal with Lucifier. He promises his soul for a twenty-four year service from a devil named Mepahstophilis.

Doctor Faustus thoroughly enjoyed the adventure. He has asked Mephastophilis to summon the great beauty from the ancient world Helen of Troy twice to parade her allure, to brag that he could possess her and to impress a group of scholars.

In the end, Doctor Faustus failed to repent and when his time was up, a host of devils escorted his soul to hell.
