Doctor faustus is composed in which literary form

Doctor Faustus, by Christopher Marlowe, is a tragedy written at Elizabethan times and it was performed for the first time in 1604.

As regards literary forms, it is a MORALITY PLAY since the main character, Dr. Faustus, is prompt to corruption. However, at the end of the play and knowing that he is going to die, he prays for redemption.  

even though there may be variations in human emotions over time, the poem “ a contribution to statistics” by wislawa symborska suggests that the only unchangeable characteristic is mortality.

the author poses a distinction between the approximate and non-approximate numbers which correspond to our need for certainty in life and the difficulty of achieving it. our efforts to measure the exact often fail because the world is not always clearly structured .the poem seems to imply   that the only thing that is certain and has an exact number is death.
