When and why did Greeks stop being influential in philosophy?

The Roman Empire happened. Greece became a providence of the Roman Empire and Athens declined as the intellectual center of thought, whereas Alexandria in Egypt and Rome grew. By this time, the most influential philosophers of the schools of philosophy that were originally Greek, such as neopythagoreanism and neoplatonism, were from various parts of the Roman Empire. Galen, for example of intellectuals at this time, though a Greek born in Pergamon (modern-day Turkey), did most of his work in Rome.
