I want to know the answer to the following question:
When did the religions of the past begin to dissipate ?
All the background I'm provided with is that "However, Greece itself had a tendency to cling to paganism and was not one of the influential centers of early Christianity: in fact, some ancient Greek religious practices remained in vogue until the end of the 4th century, with some areas such as the southeastern Peloponnese remaining pagan until well into the 10th century AD.". Is that enough to answer the question?
Answer: no
