I want to know the answer to the following question:
What famous Greek author did Athanasius  quote?
All the background I'm provided with is that "Athanasius's earliest work, Against the Heathen – On the Incarnation (written before 319), bears traces of Origenist Alexandrian thought (such as repeatedly quoting Plato and used a definition from Aristotle's Organon) but in an orthodox way.". Is that enough to answer the question?
Answer: no
