How did the Greeks steer their ships?

The ancient Greeks primarily steered their ships using a combination of a large steering oar, known as a "stern oar," positioned at the ship's stern, and the skill of the helmsman. This oar allowed for precise control of the vessel's direction, while the crew worked in unison to navigate using sail and oar power. Additionally, they relied on their knowledge of wind patterns and coastal geography to guide their journeys.
