Athena, Hestia and Artemis are regarded as the three goddesses on Olympus. The legend that Athena became the patron saint of Athens has something to do with the competition between the goddess and Poseidon. When Athens was first built by a Phoenician, Poseidon competed with Athena for the honor of naming it. The man who can provide the most useful things for mankind will become the patron saint of the city.
Because it was Zeus's head that gave birth to Athena, she became the God of wisdom. The Greeks have great respect for Athena. Athens, the capital of Greece, was named after her. Athena once made a symbol of peace grow on the rock, fruit rich, leafy olive tree, thus became the patron saint of Athens.
