The article is dedicated to review of different opinions about character and fea- tures of Synesius' Neoplatonic philosophy. The main question, which has been the matter of discussion until now, is: was Synesius a representative of Porphyr- ian tradition of Neoplatonism or of Jamblichus' one? In addition the problem of Christian background of Synesius has been regarded. The discussion has been initiated with the statement by Henry Marrou, that Synesius cannot be consid- ered as an original philosopher, and that he can be studied only as a represen- tative of the intellectual tradition of Alexandria. During the discussion of this statement the researchers came to conclusion, that theurgic elements of thought, Jamblichus' philosophical tradition and the influence of Christianity were un- derestimated in Synesius' case. In result we observe today an attempt to bring back Synesius into the history of Late antique Philosophy.
