Phoenician Navigation and Seafaring Knowledge

The Phoenician cities stood along the eastern Mediterranean coast, in the region of modern Lebanon and adjoining coastal Syria and Israel. Their sailors linked these ports with islands and shores across the sea. Planning a passage meant choosing not only a destination but a way to reach it: follow a coast and its landmarks, cross open water, or combine both, while judging wind, current, shelter and supplies.

A ship’s sail, steering oars and crew shaped those choices. A favorable wind could carry a square sail toward a destination, while a contrary wind or current could slow the passage or make another route preferable. Oars helped with close manoeuvres and short movements. Water, food and the availability of a safe place to wait also affected how far a crew could travel before replenishing its stores.

Coastal landmarks and open-water choices

Coasting offered a sequence of visible reference points: headlands, islands, high ground and harbor entrances. Familiarity with those features helped a crew recognize where it was and choose a place to shelter or replenish water. The coast also presented hazards. Reefs, shoals and exposed capes could make a close passage dangerous, and a ship driven toward land by wind needed room to turn away.

A more direct crossing could save distance, but it placed greater weight on keeping a heading and estimating when land should appear. Crews could choose a route that used a long stretch of open water, then approach a destination along a known coast. The two late eighth-century BCE wrecks named Tanit and Elissa, found about twenty miles west of Ashkelon, show that Phoenician merchant ships made such offshore passages. Their cargoes included wine jars; Egypt and Carthage have been proposed as destinations. The ships were lost in a storm in deep water, and their positions show that a voyage could carry a vessel well beyond the immediate shoreline.

Wind, weather and the timing of a passage

Wind direction mattered as much as distance. A wind that carried a ship toward its destination might make a crossing practical, while the same route on a return journey could mean waiting or taking a different course. Currents could likewise help a vessel along or resist its progress. The Mediterranean’s weather also varied by season and locality, so crews assessed the conditions along the route rather than relying on a single sailing calendar.

The third-century BCE Greek poet Aratus gives a later literary view of how seasonal winds affected seafaring. He describes the Etesians, a recurring summer wind pattern, rising in midsummer. In his poem, voyages relying on oars then become unsuitable. He recommends broad-beamed sailing ships. A helmsman could work toward a contrary wind by steering on angled courses and changing tack, while the crew adjusted the sail. His passage describes Greek seafaring weather knowledge, not a Phoenician rule for every ship or route.

A fifth-century BCE customs register, a record of inspected ships and their duties, was written in Aramaic and found at Elephantine in southern Egypt. It records Phoenician traffic at an Egyptian port; six of the listed ships are identified as Phoenician. One reconstruction places a Phoenician merchant ship’s departure from the port on 14 December, a dated example of late-year sailing in the eastern Mediterranean.

Using stars to keep a direction

Aratus also records a difference between the constellations Greek and Phoenician sailors used to steer. He says Greeks steered by Helice, the Great Bear, while Phoenicians crossing the sea trusted Cynosura, the Little Bear. Its stars circled in a smaller path near the north celestial pole, making the constellation a useful reference for finding north and maintaining a heading. Aratus presents sailors from Sidon, a Phoenician port city, using it to steer a straight course.

Cynosura was a group of stars, not a single star like today’s Polaris. Earth’s axis slowly changes direction over centuries, so Polaris was not next to the celestial pole in the first millennium BCE. The Little Bear nevertheless gave sailors a recognizable pattern near the northern pivot of the night sky. Aratus’s third-century BCE poem preserves a Greek account of this Phoenician practice and carries that knowledge into a written description of the stars.

Approaching land and holding an anchorage

As a ship approached a harbor, the crew needed to judge whether there was enough water beneath the hull. A sounding lead, a weight lowered on a line, measured depth and could bring up a sample of the bottom. By the fifth century BCE, such equipment was in use in the wider Mediterranean; in familiar shallows, a depth reading and the material brought up could help a sailor avoid a reef or select a channel.

Anchoring let a vessel hold position while the crew waited, unloaded or prepared to enter a harbor. The Phoenician wreck Mazarrón II, near modern Mazarrón in southeastern Spain, dates to the second half of the seventh or first half of the sixth century BCE. It preserves a wooden anchor with a lead crosspiece, or stock, still tied to its rope.

Routes, access and shared knowledge

Seafaring knowledge could also pass between communities through contact and writing. Aratus’s poem describes a Phoenician method to Greek readers, and the seventh-century BCE treaty between Assyrian king Esarhaddon and Baal, king of Tyre, set out ports and trade routes available to Tyrian ships. It lists places including Akko, Dor and Byblos, showing that route planning also depended on permission to call at ports beyond a city’s own territory.

Later Roman sources mention voyages attributed to Hanno and Himilco. Pliny briefly notes Himilco’s expedition to explore Europe’s outer coasts, and the Latin poet Avienus cites material attributed to him. Their claimed destinations are treated separately in Reports of voyages.
