Cook employed Tupaia, a Polynesian polymath, as a navigator and cultural mediator.

The ancient Greeks were a maritime civilisation, launching and conducting extensive seafaring trade and exploration missions. We know about them through their writings and legends – the Jason and the Argonauts myth springs to mind. But how many of us, particularly in Australia, realise that we are close to a seafaring people whose achievements surpass that of the ancient Greeks?
I am referring to the Polynesians. They were navigating and seafaring over thousands of nautical miles, centuries before other maritime societies.
While the European Vikings were just beginning their Atlantic maritime travels, the Polynesians were already settling the thousands of islands within the 300 000 to 310 000 square kilometre area that makes up the region of Polynesia. The Polynesian triangle is the area bounded by Hawaii in the north, New Zealand in the southwest, and Rapa Nui (Easter Island) in the east. They began their navigational explorations in 1000 BCE, and settled every island, volcanic or otherwise, by 1250 CE.

They did so by accumulating and passing on to future generations navigational knowledge and skills. Their seafaring covered the Pacific Ocean – in the days when there was no GPS or electronic tracking. Their skill in navigating such a vast ocean territory is truly extraordinary.
The Polynesians did not know about the magnetic poles, nor did they have a compass or sextant. They did develop their own version of the compass, a celestial navigation system – a star compass, if you will. They had a system for dividing the sky into sections, memorising the star patterns in each section. They calculated time by the position of the sun over the horizon.
They also studied the ocean swells and currents, determining the direction of travel by using those currents for speed. Their canoes were built for manoeuvrability and endurance for those long ocean voyages. They navigated by the migratory patterns of birds, identifying which species migrated when during the year and in what season. The elders of the Polynesian nations were a kind of university, passing on their wisdom to the younger generations.
The Pacific Ocean was the foundational geographic feature of Polynesian society, in much the same way as the Mediterranean was for Ancient Greek cities.
It is no exaggeration to state, as Karl Sheppard does over at the History TL:DR substack website, the Polynesians created the most extensive maritime civilisation the world has ever known.
One of the people who used Polynesian navigation knowledge was Captain James Cook.
Let’s recognise the indispensable role of Tupaia
Cook arrived in Tahiti in 1769. His knowledge of the Pacific and its peoples was limited, to say the least. He was helped by a remarkable Polynesian navigator and high priest, Tupaia. Born in 1725, Tupaia was an educated person, a kind of aristocrat in the kinship-organised kingdoms of Polynesian nations. His role was a custodian of astronomical and navigational education, to pass on the knowledge of maritime navigation and the natural environment. He spoke several Polynesian languages.
Born in what Europeans call the Society Islands, he approached the British when the HMS Endeavour arrived. He sought their help in a conflict his people had with a rival nation. His knowledge of the islands, the edible plants, the depth of the seas, the location of coral reefs, made him an indispensable navigator for Captain Cook. Tupaia basically took navigational control of the Endeavour, given the depth and skill of Polynesian seafaring.
Cook entrusted Tupaia with serving as a kind of cultural mediator with other Polynesian nations, particularly the Māori of New Zealand- Aoetearoa. Tupaia’s skills as a negotiator came into play, and Cook’s voyaging and interaction with the indigenous nations would not have been possible without the support of Tupaia.
The British understood the pivotal role that Tupaia played in their success – their goal was to reach the little understood land of Australia. Polynesian seafaring knowledge, via the teacher Tupaia, enabled the British to survive in unknown waters, find reliable food supplies, and navigate the cultural landscape with the Polynesian peoples.
The indigenous people of Australia are not Polynesian, but Melanesian. Tupaia did not know any of the languages native to the indigenous Australian nation, nor did they understand his. So Tupaia’s role as a cultural mediator ended. Sadly, Tupaia died in the Dutch East Indies of a shipborne illness (most likely either dysentery or malaria) in 1770.
His crucial role as navigator and cultural mediator was ignored by the British. Only in recent years has Tupaia received the kind of recognition that he richly deserved.
There are numerous Captain Cook statues dotting the landscape across Australian cities. In the wake of the debates regarding decolonisation, the toppling of statues of reprehensible figures has arisen in Australia. Should we remove the statues and memorials dedicated to Captain Cook? There are those who wish to retain the Cook statues as they are. If that is the case, and the majority of my fellow Australians decide to keep said statues, I will respect their decision.
I have an alternative suggestion. At the base of each Cook statue let’s attach a plaque of information which states that Cook’s success would have been impossible with Tupaia, the Polynesian navigator. In much that same way that paintings are accompanied by a brief paragraph explaining their provision, each Cook statue should carry a disclaimer that Cook’s hero status was entirely dependent on the knowledge of the Polynesian maritime navigator to whom he refused to give credit.
