Strait of Magellan: Features

The Strait of Magellan is a navigable sea route immediately south of mainland South America and north of Tierra del Fuego.

Two of the most decorative maps of the Magellan Strait, from the golden age of Dutch cartography, the seventeenth century, from two of the most famous mapmaking families, Hondius and Blaeu. 
 

1635: Hondius, Jodocus, 1594/5–1629. 

Though published in the same year, the maps differ substantially in the shape of Tierra del Fuego and the representation of Cape Horn, with Blaeu’s following outdated cartography. They both share the same table, keyed to points in the strait, for example, a penguin island (a) and a new strait (R,S,T). However, Blaeu’s map continues the idea that Cape Horn is the promontory of a cape, whereas Hondius’s map correctly presents it as an island, following the 1624 confirmation by fellow countryman, Admiral Jacques L’Hermite (1582–1624). Moreover, Hondius shows how the northwestern peninsula of Tierra del Fuego breaks up into islands; here, also, the slanting of the territory begins to mirror the true shape of the land. Blaeu’s map is notable for its scale, which illustrates how, with Mercator’s projection, distances increase toward the poles.

Several Fuegians, naked or scantily dressed, stand next to it, reflecting what explorers had reported with both shock and surprise—that the natives of the territory appear comfortable in frigid weather with nothing on. To his credit, Blaeu has deleted any reference to Patagonian giants, while Hondius’s map still bears a note claiming they exist.

The strait is approximately 570 kilometres (310 nmi; 350 mi) long and about 2 kilometres (1.1 nmi; 1.2 mi) wide at its narrowest point (Carlos III Island, west of Cape Froward).[2] The northwestern portion of the strait is connected with other sheltered waterways via the Smyth Channel. This area is similar to the Inside Passage of Alaska. South of Cape Froward, the principal shipping route follows the Magdalena Channel.

The eastern opening is a wide bay on the border of Chile and Argentina between Punta Dúngeness on the mainland and Cabo del Espíritu Santo on Tierra del Fuego, the border as defined in the Treaty of Peace and Friendship of 1984 between Chile and Argentina. Immediately west are Primera Angostura and Segunda Angostura, narrows formed by two terminal moraines of different ages.[3] The Primera Angostura is the closest approach of Isla Grande de Tierra del Fuego to the mainland of South America. Farther west lies Magdalena Island, part of Los Pingüinos Natural Monument. The strait's southern boundary in the east follows first the shoreline of the Isla Grande de Tierra del Fuego, then the northern end of the Whiteside Channel and the shoreline of Dawson Island.

The western part of the strait leads northwest from the northern end of the Magdalena Channel to the strait's Pacific entrance. This portion of the strait is flanked on the south by Capitán Aracena Island, Clarence Island, Santa Inés Island, Desolación Island (Cabo Pilar) and other smaller islands, and on the north by Brunswick Peninsula, Riesco Island, Muñoz Gamero Peninsula, Manuel Rodriguez Island and other minor islands of the Queen Adelaide Archipelago. Two narrow channels connect the strait with Seno Otway and Seno Skyring. A broader channel, Smyth Channel, leads north from the strait between Muñoz Gamero Peninsula and Manuel Rodriguez Island. Francisco Coloane Coastal and Marine Protected Area, a sanctuary for Humpback Whales, is located in this area. This part of the strait lies on the elongated Magallanes-Fagnano Fault, which marks a plate boundary between the South American Plate and the Scotia Plate. This fault continues southward under the Almirantazgo Fjord and then below the Fagnano Lake.

Polynesia's Genius Navigators

How did the first inhabitants of Easter Island arrive? It is the most remote inhabited island on Earth. The coast of Chile lies 2,300 miles to the east, Tahiti 2,500 miles to the northwest, and the nearest island, with a total population of 54 people, is tiny Pitcairn, 1,400 miles to the west. The answer lies in the deeply rooted traditions of Polynesian culture.

For the ancient Polynesians, finding Easter Island, a small 64-square-mile speck in this vast ocean, must have been like finding a needle in a haystack; but the Polynesian community today is convinced their navigators intuitively discovered and settled this island. "At the backbone of the maritime tradition lies the outrigger canoe," explains archeologist and Easter Island specialist Jo Anne Van Tilburg, "the quintessential symbol of Polynesian mastery of the sea. The outrigger canoe is today part of every Polynesian island child's upbringing, except on Easter Island. There, the outrigger canoe was lost sometime in the mid-1800s." Van Tilburg has been instrumental in reintroducing three outrigger canoes to the island. The islanders' loss of their seafaring past, according to Van Tilburg, "took away the traditional link people had with the sea."

For Van Tilburg, the Polynesian canoe is a metaphor in her theories of how the Easter Islanders transported and erected their 15-ton moai. "It's not much different from erecting a mast on a very large canoe. It's a transfer of technology from one industry to another. The people who built these structures were both sailors and farmers, and they used their seafaring technology to help them in moving and erecting their moai....Erecting a mast on a ship or a statue on a platform requires similar abilities, skills, and tools."

Seminar launches bamboo raft to learn about indigenous seafarers

Experts gathered for a special boat launching in the eastern county of Taitung as part of a seminar in which elders of the indigenous Amis Tribe demonstrated how their ancestors navigated the seas in bamboo rafts.

The seminar on indigenous navigation practices, sponsored by the Taitung County Austronesian Community College, brought experts in history, cultural studies and archeology together to discuss how Taiwan's native Austronesian population spread across the islands of the South Pacific.

Bamboo rafts were the primary method of marine transportation for peoples living along the Taitung coast, said Jesse Liu, a professor at National Taitung University. It would not have been uncommon to see over 100 such rafts scattered along the beaches before they were replaced with modern motorboats and rafts made from plastic, he said.

The traditional vessels had been forgotten until the community college began working with indigenous tribes to remake them in 2003, he said.

More than just tools, the rafts represent the seafaring culture of the region. Studying the vessels can provide valuable reference points for research on human navigation and cultural asset preservation, he said.

The Amis Tribe is one of six indigenous peoples that call Taitung home, along with the Paiwan, Rukai, Bunun, Puyuma and Yami Tribes.

Academia Sinica research fellow Liu Yi-chang, who was also at the seminar, said that he had once seen a large bamboo craft off Taiwan's southeastern coast in 1980, which he believes was built for long-distance voyages.

He surmised that Taiwan's indigenous population traveled to the island on bamboo rafts from what is today China's Zhejiang and Fujian Provinces at some point during the Paleolithic Period.

Polynesian Triangle

 

A projection of the Polynesian triangle on the globe.

The Polynesian Triangle is a geographical region of the Pacific Ocean with Hawaiʻi (1), New Zealand (Aotearoa) (2) and Rapa Nui (3) at its corners. At the center is Tahiti (5), with Samoa (4) to the west.

The Polynesian Triangle is a region of the Pacific Ocean with three island groups at its corners: Hawaiʻi, Easter Island (Rapa Nui) and New Zealand. It is often used as a simple way to define Polynesia.

The many island cultures within this vast triangle speak Polynesian languages, which are classified by linguists as part of the Oceanic subgroup of Malayo-Polynesian. They ultimately derive from the proto-Austronesian language spoken in Southeast Asia 5,000 years ago. Polynesians also share similar cultural traditions, arts, religion, and sciences. Anthropologists believe that all modern Polynesian cultures descend from a single protoculture established in the South Pacific by migrant Malayo-Polynesian people (see also Lapita).

Major Polynesian cultures include New Zealand Māori, Native Hawaiians, and the indigenous peoples of Easter Island, the Marquesas, Sāmoa, American Samoa, French Polynesia, the Cook Islands and Tonga.

There is also some evidence of Polynesian visits to some of the sub-Antarctic islands to the south of New Zealand, which are outside of Polynesia proper. A shard of pottery has been found in the Antipodes Islands, and is now in the Te Papa museum in Wellington, and there are also remains of a Polynesian settlement dating back to the 13th century on Enderby Island in the Auckland Islands.

There are also numerous Polynesian Outlier islands outside the triangle in neighboring Melanesia and Micronesia.

Secrets of Ancient Navigators: Land and Air

How did mariners of old navigate their way around the open ocean?

By Peter Tyson

The first seafarers kept in sight of land. That was the first trick of navigation—follow the coast. To find an old fishing ground or the way through a shoal, one could line up landmarks, such as a near rock against a distant point on land; doing that in two directions at once gave a more or less precise geometric location on the surface of the sea. Sounding using a lead and line also helped. "When you get 11 fathoms and ooze on the lead, you are a day's journey out from Alexandria," wrote Herodotus in the fourth century B.C. The Greeks even learned to navigate from one island to the next in their archipelago, a Greek word meaning "preëminent sea." They may have followed clouds, which form over land, or odors, which can carry far out to sea.

But what if land were nowhere nearby? The Phoenicians looked to the heavens. The sun moving across the commonly cloudless Mediterranean sky gave them their direction and quarter. The quarters we know today as east and west the Phoenicians knew as Asu (sunrise) and Ereb (sunset), labels that live today in the names Asia and Europe. At night, they steered by the stars. At any one time in the year at any one point on the globe, the sun and stars are found above the horizon at certain fixed "heights"—a distance that mariners can measure with as simple an instrument as one's fingers, laid horizontally atop one another and held at arm's length. The philosopher Thales of Miletos, as the Alexandrian poet Kallimachos recorded, taught Ionian sailors to navigate by the Little Bear constellation fully 600 years before the birth of Christ.

 Now to Miletos he steered his course
That was the teaching of old Thales
Who in bygone days gauged the stars
Of the Little Bear by which the Phoenicians
Steered across the seas.

Tupaia: Captain Cook's Polynesian Navigator and Translator

Captain james Cook visited the Hawaiian islands in 1778. When he came ashore, the people mistook him for one of their gods. This illustration shows the Hawaiians offering gifts to the English captain.

On his first voyage of Pacific exploration Cook had the services of a Polynesian navigator, Tupaia, who drew a hand-drawn Chart of the islands within 2,000 miles (3,200 km) radius (to the north and west) of his home island of Ra'iatea. Tupaia had knowledge of 130 islands and named 74 on his Chart. Tupaia had navigated from Ra'iatea in short voyages to 13 islands. He had not visited western Polynesia, as since his grandfather’s time the extent of voyaging by Raiateans had diminished to the islands of eastern Polynesia. His grandfather and father had passed to Tupaia the knowledge as to the location of the major islands of western Polynesia and the navigation information necessary to voyage to Fiji, Samoa and Tonga.

Tupaia took Taiata, a servant-boy, with him on HMS Endeavour. Taiata’s experiences were described in the officers’ journals only occasionally, but this engraving of him has survived, based on a lost sketch by Sydney Parkinson. "The Lad Taiyota, Native of Otaheite, in the Dress of his Country," engraved by R. B. Godfrey. S. Parkinson, A Voyage to the South Seas (1773), pl. IX, fp.66. © The Trustees of the British Museum.

Tupaia was a respected figure in the Society Islands and something of a virtuoso. A member of the elite arioi society of travelers and performers for the god ‘Oro, he was a ritual specialist, skillful navigator, and negotiator. He had also witnessed in 1767 the extraordinary visit of the first ship from beyond the Pacific: Samuel Wallis’s Dolphin. He knew something of what to expect from these visitors. He established a friendship with the naturalist Joseph Banks, helped Cook in relations with chiefs and learned from the ship’s artists how to draw in European style. Near the end of the Endeavour’s stay he announced he was going to accompany them to England. Cook and Banks, on the lookout for a guide, felt he "was the likeliest person to answer our purpose."

After leaving Tahiti, the Endeavour made several stops among the Society Island archipelago. In each place Tupaia used the correct ceremonial forms when greeting the chiefs, easing some of the tensions of these early meetings across cultural divides. In August they departed, as Banks said, "in search of what chance and Tupaia might direct us to."

They steered southward towards New Zealand, to try to determine if it was the northern tip of a great southern continent. Tupaia drew maps and read the currents, weather, and sky. On reaching New Zealand, Tupaia helped establish working relationships between the Maori people and the European visitors. He was able to translate, as the language of the Society Islands was the original basis of the language of the Maori. His lineage was important: he was from the Maori’s ancestral homeland, Hawaiki (Ra’iatea), and was seen to hold substantial spiritual power (mana). There were still violent clashes and misunderstandings. Tupaia, though, created a lasting impression on Maori communities and it was the great priest, rather than Cook or Banks, who was most persistently asked after when voyagers stopped by.

After establishing that the two islands of New Zealand were not the bountiful continent they sought, Cook and his men departed for the east coast of Australia. In April 1770, Cook tried to land with a few officers, the naturalist Sir Joseph Banks, and Tupaia in a bay that would later form part of Sydney. Two men (of the Gweagal or Eora people) met them with shouts and spears. Tupaia tried in vain to find any words in common and Cook offered gifts, but the visitors only managed to get ashore after firing on the men. Without the ability to obtain food and information from the locals, Cook had to continue on up the coast. Tupaia was of help in northern Australia, when he was able to establish a trusting relationship with the Guugu-Yimithirr people.

From Australia, the voyagers made their way to Dutch Batavia (present-day Jakarta). There, in December 1770, Tupaia and his servant Taiata fell ill. Dismayed at ever having left Tahiti, Tupaia died a few days after Taiata.

Polynesia's Genius Navigators

Hawaiian navigators sailing multi-hulled canoe, ca 1781

A world of water

The people of the Pacific are intimately tied to the ocean. They sailed the sea hundreds of years before Europeans, using voyaging canoes crafted from island materials and stone tools. The Polynesians approached the open ocean with respect; indeed, the ocean was integrated naturally into Polynesian culture, as they came from small islands surrounded by vast ocean expanses. No other culture embraced the open sea so fully.

For the continental Europeans, on the other hand, the ocean was looked upon as a menacing world that only the bravest explorers ventured upon for long periods of time. And even these explorers felt at odds with the ocean upon which they traveled. One of Magellan's chroniclers described "a sea so vast the human mind can scarcely grasp it." To a Polynesian islander, the world is primarily aquatic, since the Pacific ocean covers more area than land in this region. The Pacific, in fact, covers one-third of the Earth's surface.

a learned art

In island culture, the double canoe and its navigator were integral to the survival of the people. As an island became overpopulated, navigators were sent out to sail uncharted seas to find undiscovered islands.

For weeks, they would live aboard boats made from wood and lashings of braided fiber. Thousands of miles were traversed, without the aid of sextants or compasses. The ancient Polynesians navigated their canoes by the stars and other signs that came from the ocean and sky. Navigation was a precise science, a learned art that was passed on verbally from one navigator to another for countless generations.

In 1768, as he sailed from Tahiti, Captain Cook had an additional passenger on board his ship, a Tahitian navigator named Tupaia. Tupaia guided Cook 300 miles south to Rurutu, a small Polynesian island, proving he could navigate from his homeland to a distant island.

Cook was amazed to find that Tupaia could always point in the exact direction in which Tahiti lay, without the use of the ship's charts. Sadly, Cook was never able to learn and document Tupaia's navigational techniques, for Tupaia, and many of Cook's crew, died of malaria in the Dutch East Indies. Unlike later visitors to the South Pacific, Cook understood that Polynesian navigators could guide canoes across the Pacific over great distances.

But these navigational skills, along with the double canoe, disappeared with the emergence of Western technology, which mariners the world over came to rely on.

Polynesian Navigation

Polynesian navigation is a system of navigation used by Polynesians to make long voyages across thousands of miles of open ocean.

Navigators traveled to small inhabited islands using only their own senses and knowledge passed by oral tradition from navigator to apprentice, often in the form of song. In order to locate directions at various times of day and year, Polynesian navigators memorize important facts: the motion of specific stars, so where they would rise and set on the horizon of the ocean; weather and the seasons of travel; wildlife species (which gather at particular positions); the direction, size and, speed of ocean waves; colors of the sea and sky, especially how clouds would cluster at the locations of some islands; and angles for approaching harbors.

Outrigger canoes at Waikiki beach, late 1800s

These wayfinding techniques along with their unique outrigger canoe construction methods have been kept as guild secrets. Generally each island maintained a guild of navigators who had very high status and in times of famine or difficulty these navigators could trade for aid or evacuate people to neighboring islands. To this day, the original methods of Polynesian Navigation are still taught in the Polynesian outlier of Taumako Island in the Solomon Islands.

Ancient Navigators: Polynesian Navigation

Heeding the flight-paths of birds was just one of numerous haven-finding methods employed by the Polynesians, whose navigational feats arguably have never been surpassed. The Polynesians travelled over thousands of miles of trackless ocean to people remote islands throughout the southern Pacific. Like Eskimos study the snow, the Polynesians watched the waves, whose direction and type relinquished useful navigational secrets. They followed the faint gleam cast on the horizon by tiny islets still out of sight below the rim of the world. 

Seafarers of the Marshall Islands built elaborate maps out of palm twigs and cowrie shells. These ingenious charts, which exist today only in museums, denoted everything from the position of islands to the prevailing direction of the swell.

This massive statue from Easter Island was buried up to the chest. When uncovered it revealed this image of a sailed ship.

Sigiriya Frescoes

Hidden in a cave along the citadel at Sigiriya are some of the most magnificent ancient frescoes in South Asia.

Halfway on Sigiriya-rock, you can see very special mural paintings. They are non-religious representations of women, of which some have been preserved very well. Some sources even say that the whole western face of the rock used to be covered with these paintings (of 500 women). 

John Still in 1907 suggested, "The whole face of the hill appears to have been a gigantic picture gallery... the largest picture in the world perhaps". The paintings would have covered most of the western face of the rock, an area 140 metres long and 40 metres high. There are references in the graffiti to 500 ladies in these paintings. However, most have been lost forever. More frescoes, different from those on the rock face, can be seen elsewhere, for example on the ceiling of the location called the "Cobra Hood Cave".

Although the frescoes are classified as in the Anuradhapura period, the painting style is considered unique; the line and style of application of the paintings differing from Anuradhapura paintings. The lines are painted in a form which enhances the sense of volume of the figures. The paint has been applied in sweeping strokes, using more pressure on one side, giving the effect of a deeper colour tone towards the edge. Other paintings of the Anuradhapura period contain similar approaches to painting, but do not have the sketchy lines of the Sigiriya style, having a distinct artists' boundary line. The true identity of the ladies in these paintings still have not been confirmed. There are various ideas about their identity. Some believe that they are the wives of the king while some think that they are women taking part in religious observances. These pictures have a close resemblance to some of the paintings seen in the Ajanta caves in India
