I want to know the answer to the following question:
What depicts the Gigantomachy on the acropolis of the city?
All the background I'm provided with is that "Eumenes II turned Pergamon into a centre of culture and science by establishing the library of Pergamum which was said to be second only to the library of Alexandria with 200,000 volumes according to Plutarch.". Is that enough to answer the question?
