  Since Proclus’ extant works contain almost no evidence about his biography, we have to rely on the information transmitted by his direct pupil Marinus of Neapolis in the eulogy he devoted to his predecessor Proclus or on Happiness. Moreover, some scattered remarks on Proclus and valuable information about the schools in Athens and Alexandria can be found in Damascius’ Life of Isidorus (called by other scholars The Philosophical History). As with Porphyry’s Life of Plotinus, both Marinus’ and Damascius’ works are biographies written by students praising extensively the achievements of their teachers both in doctrine and in philosophical life.
