Phoenician Navigation: Did They Use the North Star?

No. The Phoenicians (c. 1500–300 BCE), master mariners of the Mediterranean, did not rely on the North Star (Polaris) for navigation.

Why not?

• Polaris was not the pole star in their era; due to precession, Thuban (Alpha Draconis) was closer to the celestial pole c. 2700 BCE, but by Phoenician times no bright star marked the pole accurately.
• Mediterranean latitudes (30°–45° N) place the celestial pole at moderate altitude; horizon-based coastal piloting was more practical.

What they used:

• Sun: Altitude at noon for latitude; sunrise/sunset azimuth for direction.
• Constellations: Ursa Major (Big Dipper) and Cassiopeia—circumpolar, easy to identify, used to locate true north.
• Coastal Landmarks: Headlands, islands, mountain peaks.
• Dead Reckoning: Speed (chip log), time, course.
• Soundings: Lead line for depth and bottom composition.

Their open-sea voyages (e.g., to Britain, West Africa, possibly the Canaries) combined these methods with seasonal wind knowledge.
