of the Greeks. Apart from technical skills and cultural influences, of paramount significance was that the Greeks acquired the alphabet c. 800 BCE. Another factor was the ease and frequency of intra-Greek travel, which led to the blending and comparison of ideas. During the sixth century BCE, various philosophers and other thinkers moved easily around Greece, especially visiting pan-Hellenic festivals. While long-distance communication was difficult during ancient times, persons, philosophers, and books moved through other parts of the Greek peninsula, the Aegean islands, and Magna Graecia, a coastal area in Southern Italy. The democratic political system of independent poleis also contributed to the rise of philosophy. Most Greek towns were not ruled by autocrats or priests, allowing citizens to question freely a wide range of issues. Various poleis flourished and became wealthy, especially Miletus. which was a centre of trade and production during the early phases of pre-Socratic philosophy. Trade of grain, oil, wine, and other commodities among each polis and colonies meant these towns were not isolated but embedded – and economically dependent – on a complex and changeable web of trade routes. Greek mythology also influenced the birth of philosophy. The philosophers' ideas, were, to a certain extent, answers to questions that were subtly present in the work of Homer and Hesiod. The pre-Socratics arose from a world dominated by myths, sacred places, and local deities. The work of epic poets such as Homer, Hesiod and others reflected this environment. They are considered predecessors of the pre-Socratics since they seek to address the origin of the world and to organize traditional folklore and legends systematically. However, their answers were rather simplistic and resisted naturalistic explanations, hence they were far from being named as philosophers. Greek popular religion contained many features of the religions of neighboring civilizations, such as the Egyptians, Mesopotamians, and Hittites. The first pre-Socratic philosophers also traveled extensively to other lands, meaning that pre-Socratic thought had roots abroad as well as domestically. Homer, in his two epic poems, not only personifies gods and other natural phenomena, such as the Night, but he hints at some views on the origin and the nature of the world that came under scrutiny by the pre-Socratics. In his epic poem Theogony (literally meaning the birth of gods) Hesiod (c. 700 BCE) describes the origin of gods, and apart from the solid mythical structure, one can notice an attempt towards organizing
