Evidence of Ancient Trade - or Ancient Inheritance?

From Past-Horizons.com  Also sent to me separately by Isis.  A mystery: how did this old piece of Asian-cast bronze get to Cape Espenberg, Alaska and end up in the ruins of a 1,000 year old Inupiat house?  According to a comment made at the end of the article that was posted at Past Horizons by a Steve Mitchell one day ago:

Given it's size and together with the additional straight piece, it is almost certainly the end of a horse bit (snaffle bit). These were ubiquitous across the whole Steppe region during the Bronze Age. A similar object is illustrated in 'Ancient Bronzes of the Eastern Eurasian Steppes from the Arthur M Sackler Collection' by Emma C Bunker, Fig.A23,p 37 (1997).

If the Asian peoples who first migrated to the Americas thousands of years ago ever had horses initially, I haven't heard of any evidence to point to their survival after the trek to the New World -- at least, not in the Arctic regions!  Horses as we think of them didn't arrive until the Spaniards came and carried their horses with them on their ships - a feat in and of itself considering the mode of travel and the conditions at the time! 

Was this an ancient family-held object -- a remnant of life from the distant past, from a time when the ancestors of one particularInupiat family roamed the Eurasian steppes on horses?  Was the object a found object and kept because of its uniqueness?  It seems metal, as such, wasn't known to the Inupiat until much later, when they came into contact with Europeans.  Was it something that was traded?  But if so, what other evidence exists that these Cape Espenberg Inupiat people were engaged in trade with the Old World? 

I seems doubtful to me that we'll ever be able to solve the mystery of this object - it's just one more fascinating tale among a myriad of fascinating tales that make our past so intriguingly attractive to me!
Ancient bronze artefact from East Asia unearthed in Alaska
Tuesday, November 15, 2011 

A team of researchers led by the University of Colorado Boulder has discovered the first prehistoric bronze artefact made from a cast ever found in Alaska, a small, buckle-like object found in an ancient Eskimo dwelling and which likely originated in East Asia.

The artefact consists of two parts — a rectangular bar, connected to an apparently broken circular ring, said CU-Boulder Research Associate John Hoffecker, who is leading the excavation project. The object, about 2 inches by 1 inch and less than 1 inch thick, was found in August by a team excavating a roughly 1,000-year-old house that had been dug into the side of a beach ridge by early Inupiat Eskimos at Cape Espenberg on the Seward Peninsula, which lies within the Bering Land Bridge National Preserve.

Both sections of the artefact are bevelled on one side and concave on the other side, indicating it was manufactured in a mould, said Hoffecker, a fellow at CU-Boulder’s Institute of Arctic and Alpine Research. A small piece of leather found wrapped around the rectangular bar by the research team yielded a radiocarbon date of roughly A.D. 600, which does not necessarily indicate the age of the object, he said.

“I was totally astonished,” said Hoffecker. “The object appears to be older than the house we were excavating by at least a few hundred years.”

Hoffecker and his CU-Boulder colleague Owen Mason said the bronze object resembles a belt buckle and may have been used as part of a harness or horse ornament prior to its arrival in Alaska. While they speculated the Inupiat Eskimos could have used the artefact as a clasp for human clothing or perhaps as part of a shaman’s regalia, its function on both continents still remains a puzzle, they said.

Since bronze metallurgy from Alaska is unknown, the artefact likely was produced in East Asia and reflects long-distance trade from production centres in either Korea, China, Manchuria or southern Siberia, according to Mason. It conceivably could have been traded from the steppe region of southern Siberia, said Hoffecker, where people began casting bronze several thousand years ago.

Alternatively, some of the earliest Inupiat Eskimos in northwest Alaska — the direct ancestors of modern Eskimos thought to have migrated into Alaska from adjacent Siberia some 1,500 years ago — might have brought the object with them from the other side of the Bering Strait. “It was possibly valuable enough so that people hung onto it for generations, passing it down through families,” said Mason, an INSTAAR affiliate and co-investigator on the Cape Espenberg excavations.

The Seward Peninsula is a prominent, arrowhead-shaped land mass that abuts the Bering Strait separating Alaska from Siberia. The peninsula was part of the Bering Land Bridge linking Asia and North America during the last ice age when sea level had dropped dramatically, and may have been used by early peoples as a corridor to migrate from Asia into the New World some 14,000 years ago.

The artefact was discovered in August by University of California, Davis, doctoral student Jeremy Foin under 3 feet of sediment near an entryway to a house at Cape Espenberg. Other project members included Chris Darwent of UC Davis, Claire Alix of the University of Paris, Nancy Bigelow of the University of Alaska Fairbanks, Max Friesen of the University of Toronto and Gina Hernandez of the National Park Service.
“The shape of the object immediately caught my eye,” said Foin, who spotted the soil-covered artefact in an archaeological sifting screen. “After I saw that it clearly had been cast in a mould, my first thought was disbelief, quickly followed by the realisation that I had found something of potentially great significance.”

The CU-led excavations are part of a National Science Foundation-funded project designed to study human response to climate change at Cape Espenberg from A.D. 800 to A.D. 1400, a critical period of cultural change in the western Arctic, said Mason. Of particular interest are temperature and environmental changes that may be related to Earth’s Medieval Warm Period that lasted from about A.D. 950 to 1250.

“That particular time period is thought by some to be an analogue of what is happening to our environment now as Earth’s temperatures are rising,” said Mason. “One of our goals is to find out how these people adapted to a changing climate through their subsistence activities.”

The Cape Espenberg beach ridges, wave-swept deposits made of sand and sediment running parallel to the shoreline that were deposited over centuries, often are capped by blowing sand to form high dunes. The Cape Espenberg dwellings were dug into the dunes and shored up with driftwood and occasional whale bones.

The team is examining the timing and formation of the beach ridges as well as the contents of peat and pond sediment cores to help them reconstruct the sea-level history and the changing environment faced by Cape Espenberg’s settlers. Information on past climates also is contained in driftwood tree rings, and the team is working with INSTAAR affiliate Scott Elias, a University of London professor and expert on beetle fossils, who is helping the team reconstruct past temperatures at Cape Espenberg.

While the hunting of bowhead whales was a way of life for Inupiat Eskimos at Barrow and Point Hope in northwestern Alaska 1,000 years ago, it is still not clear if the Cape Espenberg people were whaling, said Mason. While whale baleen — a strong, flexible material found in the mouths of whales that acts as a food filter — and a variety of whale bones have been found during excavations there, the sea offshore is extremely shallow and some distance from modern whale migration routes. However, there is evidence of fishing and seal and caribou hunting by the group, he said.

The Inupiat Eskimos are believed to have occupied Cape Espenberg from about A.D. 1000 until the mid-1800s, said Hoffecker. They are part of the indigenous Eskimo culture that lives in Earth’s circumpolar regions like Alaska, Siberia and Canada.

The Cape Espenberg site has yielded a treasure trove of several thousand artefacts, including sealing harpoons, fishing spears and lures, a copper needle, slate knives, antler arrow points, a shovel made from a walrus scapula, a beaver incisor pendant, ceramics, and even toy bows and toy harpoons. The bronze artefact unearthed in August is currently under study by prehistoric metallurgical expert and Purdue University Assistant Professor H. Kory Cooper.
