Keywords

💡Polynesian Navigators

Polynesian navigators were skilled seafarers who sailed vast distances across the Pacific Ocean using natural clues like the stars, ocean currents, and clouds. In the video, they are central figures, demonstrating how ancient people could navigate without modern technology, using a deep understanding of the natural world to treat the ocean as a series of pathways rather than an obstacle.

💡Star Compass

The star compass was a mental map used by Polynesian navigators to determine direction by observing the positions of stars and constellations. It divided the sky into quadrants and houses, helping sailors memorize where stars rose and set throughout the year. This was a crucial navigational tool mentioned in the script to illustrate how Polynesians could orient themselves at night on open water.

💡Wa'a Kaulua (Double-hulled Canoe)

The wa'a kaulua, or double-hulled canoe, was a sturdy vessel used by Polynesians for long-distance ocean voyages. It featured two hulls for stability and was powered by sails and steered with a large oar. The video emphasizes its importance, noting that well-built canoes were essential for successful voyages across vast stretches of the Pacific.

💡Hokulea

Hokulea is a voyaging canoe that completed a worldwide journey in 2017 using traditional Polynesian navigation methods. This modern reenactment provides proof of the accuracy and effectiveness of ancient techniques, linking the legacy of Polynesian navigators to the present day. It exemplifies how this knowledge has been preserved and applied in contemporary times.

💡Ocean Swells

Ocean swells, generated by trade winds, were used by Polynesian navigators to detect direction. By observing the rocking motion of their canoes, they could sense the direction of these swells during the day, while at sunrise and sunset the low light helped them see the swells directly. These swells were part of the natural clues that enabled precise navigation.

💡Southern Cross (Newe)

The Southern Cross, or Newe, is a constellation used by Polynesian navigators in the Southern Hemisphere to estimate direction. When the North Star (Hokupa'a) was not visible, navigators would use the Southern Cross and apply mental tricks to determine the location of south. This technique was critical for navigating vast distances where there were no obvious landmarks.

💡Clouds

Clouds were another key navigational aid for Polynesian voyagers. Certain types of clouds could reflect the presence of landmasses like lagoons or mountainous islands, helping navigators find their destinations. This natural phenomenon exemplified how Polynesians relied on close observation of their environment to guide them across the ocean.

💡Manu-O-Ku (Birds)

The Manu-O-Ku, a bird with a flight range of 190 kilometers, was used by Polynesian navigators to help locate land. Once within this range, the bird could be followed back to shore. This technique underscores how Polynesians used not only celestial and environmental clues but also the behavior of wildlife to assist in navigation.

💡Oral Traditions

Oral traditions played a vital role in preserving the knowledge of Polynesian navigation. Navigational techniques were passed down through generations via storytelling, songs, and rituals. These traditions, along with petroglyphs and European explorers' accounts, provide modern historians and navigators with insights into how these voyages were undertaken.

💡Kinship with Nature

Kinship with nature refers to the deep connection Polynesian navigators had with the natural world. Their ability to 'see' the ocean as a series of pathways and their understanding of the stars, ocean currents, birds, and other natural phenomena allowed them to undertake vast journeys. The video highlights how this relationship enabled them to explore and settle the farthest reaches of the Pacific Ocean.

Transcripts

Imagine setting sail from Hawaii in a canoe.

Your target is a small island thousands of kilometers away

in the middle of the Pacific Ocean.

That's a body of water that covers more than 160 million square kilometers,

greater than all the landmasses on Earth combined.

For thousands of years,

Polynesian navigators managed voyages like this

without the help of modern navigational aids.

Ancient Polynesians used the Sun,

Moon,

stars,

planets,

ocean currents,

and clouds as guides that allowed them to see the ocean as a series of pathways

rather than an obstacle.

Their voyages began around 1500 B.C.

when the people who would settle Polynesia first set sail from Southeast Asia.

Early Polynesians eventually settled a vast area of islands

spread over 40 million square kilometers of the Pacific Ocean.

Some historians believe the voyagers moved from place to place

to avoid overpopulation.

Others, that they were driven by war.

Voyages became less frequent by around 1300 A.D.

as Polynesian societies became more rooted in specific locations.

During the voyaging period,

successful journeys depended on a number of factors:

well-built canoes,

the skill of navigators,

and weather being some of the biggest.

Voyages relied on sturdy wa'a kaulua, or double-hulled canoes,

which were powered by sails and steered with a single large oar.

Canoe building involved the whole community,

bringing together the navigators,

canoe builders,

priests,

chanters,

and hula dancers.

Navigators were keen observers of the natural world.

They were abundantly familiar with trade wind-generated ocean swells,

which typically flow northeast or southeast.

By day, navigators could identify direction

by the rocking motion of their canoes caused by these swells.

But sunrise and sunset were even more useful.

The Sun's position indicated east and west

and created low light on the ocean that made it possible to see swells directly.

At night, navigators used something called a star compass,

which wasn't a physical object, but rather a sort of mental map.

They memorized the rising and setting points of stars and constellations

at different times of the year.

They used those to divide the sky into four quadrants,

subdivided into 32 houses,

with the canoe in the middle.

So, for example, when they saw the star Pira‘atea rising from the ocean,

they knew that to be northeast.

They had some other tricks, too.

The Earth's axis points towards Hokupa'a, or the North Star,

so called because it's the one fixed point in the sky as the Earth rotates

and always indicates north.

However, it's not visible south of the Equator,

so navigators there could use a constellation called Newe,

or the Southern Cross,

and some mental tricks to estimate where south is.

For instance, draw a line through these two stars,

extend it 4.5 times,

and draw another line from there to the horizon.

That's south.

But the sky also contains navigational aids much closer to Earth,

the clouds.

Besides being useful weather cues,

under the right conditions, they can indicate landmasses.

For instance, the lagoons of Pacific atolls

can actually be seen reflected on the underside of clouds,

if you know what to look for.

And high masses of clouds can indicate mountainous islands.

Once navigators neared their destination, other clues,

such as the flight patterns of birds,

floating debris or vegetation,

and types of fish in the area helped determine the proximity of land.

For example, the Manu-O-Ku had a known flight range of 190 kilometers,

and could be followed back to shore.

So how do we know all of this?

Partially through evidence in petroglyphs,

written observations of European explorers,

and Polynesian oral traditions.

But also by trying them out for ourselves.

In 2017, a voyaging canoe called Hokulea

completed a worldwide voyage using only these techniques.

If that seems remarkable, remember the ancient Polynesians,

who through close study and kinship with nature,

were able to forge these paths across

an unfathomably vast, vibrant living ocean.
