Faust or Faustus (Latin for "auspicious" or "lucky") is the protagonist of a classic German legend. Though a highly successful scholar, he is unsatisfied, and makes a deal with the Devil, exchanging his soul for unlimited knowledge and worldly pleasures. Faust's tale is the basis for many literary, artistic, cinematic, and musical works. The meaning of the word and name has been reinterpreted through the ages. Faust, and the adjective Faustian, are often used to describe an arrangement in which an ambitious person surrenders moral integrity in order to achieve power and success: the proverbial "deal with the devil." The terms can also refer to an unquenchable thirst for knowledge.
