In India, Hinduism is very much a synthesis of various philosophical, mythological and theological points of view, which as far as I understand grew into a whole rather organically. It is also remarkably decentralised, with as many interpretations as there are people and without the more rigid structures we often see in other religions. It has proven to be very enduring, so much so that it is synonymous with India even today.
The possibility for such a synthesis of various philosophies and theological ideas existed in my opinion in the Roman Empire. Could the cross-pollination of ideas and the large amount of travel within the empire have led to an European analogue to hinduism? One that could become as synonymous with Europe as hinduism is with India? One that would survive the fall of Rome and spread north of the limes, where the mythology of Slavs and Germans did not differ all that much from that of Romans and Greeks? Perhaps hellenism is the vehicle for an unified European religious/philosophical framework I'm looking for? And how could such a framework be created?
