Ancient Quipu Found at Caral
Nov 19th 2011, 10:02

Archaeologists excavating at the ancient Peruvian coastal civilization called Caral have recovered an artifact which may represent one of the earliest forms of communication in the world, roughly equivalent in age to the cuneiform of Mesopotamia.

The early civilization known as Caral was first reported in 2001, as a collection of at least 18 separate towns and villages on the northern coast of Peru, dated to approximately 4600 years ago. The discovery was of vast importance, because, on the basis of the dates, Caral is the earliest of the sophisticated civilizations in the Americas, and was one of the few civilizations on the planet which apparently developed without a form of written communication.

Quipu Usage

Archaeologists believe that most civilizationsâ€"those that develop public projects such as monumental architecture, and have a geographically wide distribution that was controlledâ€"require some form of record keeping to arise and survive. The exceptions include the Inca civilization, which did not have anything we modern people recognize as writing. What the Inca had were quipu, a complicated system of knotted cords of different colors. Many of these quipus (also spelled khipus) were destroyed by the Spanish conquistadors in the 16th century, but approximately 200 of them dating no earlier than about 650 AD have been found. Although archaeologists do not all agree about the function of the knotted strings, one fairly compelling argument is that the quipu was a method of record keeping.

Quipu at Caral

The recovery of quipu from the civilization of Caral, if the context and dates are correct, suggests several things. First, this is additional evidence that Caral was a precursor to the Inca civilization (since the Incas also used quipu). Secondly, quipu as a tradition dates at least 2000 years older than we recognized prior to this point. Thirdly, and most importantly, if quipu were indeed a form of written communication, they are among the earliest forms of writing in the world, only slightly younger than cuneiform, which has been identified at the Mesopotamian site of Uruk approximately 3000 years BC.

As a very recently identified civilization of the world, Caral has the potential to help us rewrite human history.

Turkey (Melagris spp)
Nov 19th 2011, 10:02

The turkey (Meleagris gallapavo) was definitely domesticated in the New World, but its specific origins are somewhat problematic. Archaeological specimens of wild turkey have been found in North America that date to the Pleistocene, and turkeys were emblematic of many Woodland tribes in North America as seen at sites such as Mississippian Etowah. The earliest signs of domestication found to date appear in Maya sites such as Cobá beginning about 100 BC-100 AD.

Turkey Species

The wild turkey (Meleagris gallopavo) is indigenous to much of the eastern and southwestern US, northern Mexico and southeastern Canada. Six subspecies are recognized by biologists: eastern (Meleagris gallopavo silvestris), Florida (M. g. osceola), Rio Grande (M.g. intermedia), Merriam's (M.g. merriami), Gould's (M.g. mexicana), and southern Mexican (M.g. gallopavo). The differences among them are primarily habitat, but there are minor differences in body size and plumage coloration.

The ocellated turkey (Agriocharis ocellata or Meleagris ocellata) is considerably different in size and coloration and thought by some a separate species entirely. It is native to the Yucatán peninsula of Mexico and, interestingly enough, is today often found wandering in Maya ruins such as Tikal. The ocellated turkey is more resistant to domestication, but was among the turkeys kept in pens by the Aztecs as described by the Spanish.

Turkeys were used by precolumbian North American societies for meat and egg consumption, and their feathers were prized for decorative objects and clothing. The hollow long bones of turkeys were also adapted for use as musical instruments and bone tools.

Turkey Domestication

At the time of the Spanish colonization, there were domesticated turkeys both in Mexico among the Aztecs, and in the pueblo societies of the American southwest. Evidence suggests that the turkeys from the southwest were actually imported from Mexico about AD 300, and perhaps re-domesticated in the southwest about 1100 AD when turkey husbandry really took off. Wild turkeys were found by the European colonists throughout the eastern woodlands. Variations in coloration were noted in the 16th century, and many turkeys were carted back to Europe.

Archaeological evidence for turkey domestication accepted by scholars includes the presence of turkeys outside of their original habitats, the construction of pens, turkey burials, turkey demography including juveniles, healed long bone fractures, and the presence of quantities of eggshell. Recent work using patterned calcium absorption in eggshell to pick out shell which came from hatched eggs has added another possible route of investigation.

Silk Road
Nov 19th 2011, 10:02

The Silk Road (or Silk Route) refers to the network of trade routes crossing Asia, first reported to have been used during the Han Dynasty [206 BC-220 AD] in China. Over 4500 kilometers (2800 miles) of roadway are known, in three major trails between Chang'an in China and Rome in Italy.

Using a series of way stations and oases, the Silk Road spanned the 1900 kilometers (1200 miles) of the Gobi Desert of Mongolia and the mountainous Pamirs (the 'Roof of the World') of Tajikistan and Kyrgyzstan. Important stops on the Silk Road included Kashgar, Turfan, Yarkand, Dunhuang, and the Merv Oasis.

Although called the Silk Road, a wide variety of material goods were carried along its tracks, including silk, precious gems and metals like jade and gold, horses, apricots, melons, raisins, ceramic lustreware, and lacquerware. More importantly, the Silk Road also carried people, and so its use spread technological advances such as medical science from India and religions such as Buddhism and Islam. It was probably also along the Silk Route where industrial espionageâ€"the secret of silk manufactureâ€"was passed.

Sites: Merv Oasis, Chang'an, Palmyra

Trade Goods: Lustreware, Wootz steel, silk, horses

E-Group
Nov 18th 2011, 10:19

An E-Group is an arrangement of buildings found on upwards of 70 ancient Maya cities located primarily in the lowland Maya region of Mexico, Guatemala and Belize. Attributed to the observation of the summer and winter solstices since the 1920s, E-Groups probably had several uses, including ties to the celebrations associated with ritual calendars and ball games.

Mundo Perdido E-Group at Tikal
Plan of Mundo Perdido (Lost World) E-Group at Tikal.

The E-Group pattern includes a linear row of three platform mounds opposite a pyramidal temple with a platform on top of it (rather than a group of walled rooms). E-Groups are often located near ball courts and they often have stelae (stone markers) inscribed with dates for the beginnings of the 20-year cycle called k'atuns: all of which makes for an interesting subject of discussion.

As some of you might know, I have a lot of nerve, so I'm posting this hoping some Mayanist will shoot me down, but this Maya glyph representing the midwinter month of Yaxkin looks a tad bit like an E-Group to me. Any shooters today?

Letter of Intent

Letters of Reference < | Letter of Intent | > Writing Samples

What is a 'Letter of Intent'?

Many schools request a short statement or 'letter of intent' from you laying out research interests and the reasons why you are applying to graduate school and to that particular school. This is the document that will sell you and your research interests to the department, so for heaven's sake take as much care in preparing it as you would a term paper. Admittedly it is difficult to squeeze all your ideas onto one page (try not to make it longer; some schools specify only one page) but thanks to computers you can use a smaller typeface (but make sure its still readable). However, sneaky people that they are, some schools have gotten wise and indicate that you must use a certain font size.

What About a Thesis Topic?

You are not expected to have a thesis topic in hand, but you should give some clear idea of your geographical and topical interests and possible topics you might be interested in that will be of interest to that particular school.

In cases where you do have access to data or a project for use in a thesis, mention this. Briefly describe the nature of the data, who collected it and what you want to do with it. Also mention who has suggested you use it and who has given approval to use it. If you are involved in a project that will provide material, give information on who is running the project, what the material is or what you expect to find (if it is a new project), and confirm that you have permission to use the material.

If you don't have access to research material, write a brief statement outlining your interests and explain how you think they will tie in with the research interests of the department.

How Will You Fit into Their Department?

Remember that your letter of intent is used to assess how you will fit into the department to which you are applying. Laying out ideas and possible topics at this time will not limit your possible choice of thesis topic. Schools realize that exposure to new ideas and people can and do change a students way of thinking.
  • Write a draft of the statement and show it to people, particularly faculty members, and elicit their comments.
  • Do not use a "generic" statement that you will send to each university; tailor the statements to each individual department for which you are applying.
  • Tell the department if they have a research emphasis which interests you and mention if you have been in touch with a member of the faculty regarding potential supervision.
  • Don't try to be all things to all people and say that you want take courses from everyone in the department on topics dealing with their particular area; this just gives the impression that you don't really know what you want. Conversely if there is some particular course you want to take (for example advanced training in zooarchaeology) mention it. Also, an awareness of any lack in your background may be mentioned--for instance if you haven't completed fieldwork or lab work. This demonstrates that you are aware of your weaknesses. I know that the foregoing sounds contradictory but there is a happy medium.
  • Needless to say, type the statement, make sure that it is grammatically correct and that you run spellcheck, and have it read by someone else one final time before it is submitted.

Google Earth and Archaeology
Nov 18th 2011, 10:02

Google Earth, software that uses high resolution satellite images of the entire planet to allow the user to get an incredible moving aerial view of our world, has stimulated some serious applications in archaeology--and seriously good fun for fans of archaeology.

One of the reasons I love flying in airplanes is the view you get from the window. Soaring over vast tracks of land and getting a glimpse of large archaeological sites (if you know what to look for, and the weather is right, and you're on the right side of the plane), is one of the great modern pleasures of the world today. Sadly, security issues and rising costs have sucked most of the fun out of airline trips these days. And, let's face it, even when all the climatological forces are right, there just aren't any labels on the ground to tell you what you're looking at anyway.

Google Earth Placemarks and Archaeology

But, using Google Earth and capitalizing on the talent and time of people like JQ Jacobs, you can see high resolution satellite photographs of the world, and easily find and investigate archaeological wonders like Machu Picchu, slowly floating down the mountains or racing through the narrow valley of the Inca trail like a Jedi knight, all without leaving your computer.

Essentially, Google Earth (or just GE) is an extremely detailed, high resolution map of the world. Its users add labels called placemarkers to the map, indicating cities and restaurants and sports arenas and geocaching sites, all using a fairly sophisticated Geographic Information System client. After they've created the placemarkers, the users post a link to them on one of the bulletin boards at Google Earth. But don't let the GIS connection scare you off! After installation and a little fussing with the interface, you too can zoom along the narrow steep-sided Inca trail in Peru or poke around the landscape at Stonehenge or take a visual tour of castles in Europe. Or if you've got the time to study up, you too can add placemarkers of your own.

JQ Jacobs has long been a contributor of quality content about archaeology on the Internet. With a wink, he warns would-be users, "I'm glimpsing a possible forthcoming chronic disorder, 'Google Earth Addiction'." In February of 2006, Jacobs began posting placemark files on his website, marking several archaeological sites with a concentration on Hopewellian earthworks of the American northeast. Another user on Google Earth is simply known as H21, who has assembled placemarkers for castles in France, and Roman and Greek amphitheatres. Some of the site placemarkers on Google Earth are simple location points, but others have lots of information attached--so be careful, like anywhere else on the Internet, there be dragons, er, inaccuracies.

Survey Techniques and Google Earth

On a more serious but downright exciting note, GE has also been used successfully to survey for archaeological sites. Searching for crop marks on aerial photos is a time-tested way to identify possible archaeological sites, so it seems reasonable that high resolution satellite imagery would be a fruitful source of identification. Sure enough, researcher Scott Madry, who is leading one of the oldest large-scale remote sensing projects on the planet called GIS and Remote Sensing for Archaeology: Burgundy, France, has had great success identifying archaeological sites using Google Earth. Sitting in his office at Chapel Hill, Madry used Google Earth to identify over 100 possible sites in France; fully 25% of those were previously unrecorded.

Find the Archaeology Game

Find the Archaeology is a game on the Google Earth community bulletin board where people post an aerial photograph of an archaeological site and players must figure out where in the world it is or what in the world it is. The answer--if it's been discovered--will be in postings at the bottom of the page; sometimes printed in white lettering so if you see the words "in white" click and drag your mouse over the area. There simply isn't yet a very good structure to the bulletin board, so I've collected several of the game entries in Find the Archaeology. Sign in to Google Earth to play; you don't need to have Google Earth installed to guess.

Archaeology: What's Hot Now: La Draga (Catalonia, Spain)

Archaeology: What's Hot Now
These articles that had the largest increase in popularity over the last week // via fulltextrssfeed.com
La Draga (Catalonia, Spain)
Nov 17th 2011, 10:02

La Draga is an early Neolithic site and Alpine lake dwelling, located partly underwater and partly on the shoreline of the eastern shore of Lake Bayoles in Catalonia, Spain. The site was occupied for between 80 and 100 years at the end of the 6th millennium BC (between 5300 and 5150 cal BC, or approximately 7,200 years ago). Within the portion of the site that has remained below the water table, the preservation of organic remains is remarkable.

La Draga was located along the shoreline of Lake Bayoles for some 100 meters, and originally included an area of over 8,000 square meters (sq m), with a population of about 100 living in 16-20 huts. The best-preserved part of the site has been the focus of archaeological investigations, and it is now fenced off and in the process of being converted into an archaeological park.

Excavations have shown that all of the structures at the site date to the early Neolithic, although there are several superimposed layers, some covered by flood deposits. At the end of the occupation, the site was burned and abandoned.

Hut Construction at La Draga

To date, the excavations have identified nearly 900 trunks, stakes and building timbers representing the remains of large rectangular huts constructed of oak posts. The density of the posts (in some places more than 1.23 posts per square meter) has made identification of the buildings somewhat difficult. Nevertheless, the huts were likely rectangular, with a central row of trunks supporting a thatched roof. They likely measured approximately 10-12 meters (32-40 feet) long by 3-4 m (10-13 ft) wide. The huts stood on stilts, raised above the water line a height of approximately one meter (3 ft).

The huts were built of three to four rows of oak pillars, each some 12-15 cm (5-6 in) in diameter and 80-90 cm (30-35 in) apart. The bark on the pillars was left intact, and the lower end was modified into a bevel or point to allow it to be driven into the ground to depth of up to 2.7 m (9 ft). The top ends were fork-shaped to support the main roof beams, which were lashed to the pillars with wild clematis. The walls were constructed of branches thatched together and covered in mud and straw. Floors in the huts were made of planks and split logs, and a small hearth of pebbles and charcoal warmed the interior.

The huts were arranged in two rows between the shoreline and about 30 m (100 ft) inland. At least six phases of construction have been identified by dendrochronology, all within a period of 80-100 years.

Other Structures

Oval structures located at ground level within a relatively high and dry area and paved with stone slabs are interpreted as granaries. Within these structures were found the charred remains of wheat, barley, peas and broad beans. A palisade line was constructed which may have protected the granaries, and a causeway may have connected the lakeside house area with the higher part of the site.

Thirty-five external pit hearths, measuring between 60 and 180 centimeters (~24-30 inches) were identified at the lake edge. These are shallow pits, lined with charcoal with an upper layer of quartz pebbles. These were used to cook meat within the layer of hot pebbles, and to roast grain.

Middens were identified at the site in irregular ditches; no cemeteries have been identified to date.

Artifacts from La Draga

Plants recovered from La Draga include cereals such as wheat and barley, peas and broad beans, and fruit such as wild grapes, blackberries, pine nuts and hazelnuts. Domestic animals includ cattle, goats, and pigs.

An enormous number of wooden tools has been recovered from the site, as well as ceramics, chipped flint, and polished stone objects. Bone and horn tools include bowls, combs, rings, eyed needles, spatulas, spoons, and bird bone tubes. Several bone arrowheads, ranging between 7-12.5 cm (3-5 in) were recovered. Most of the bone came from deer, sheep, goats and cattle.

Ceramic pots were hand-built from local clay tempered with quartz and mica. Most were small and medium-sized round pots, suitable for cooking. Large cylindrical jars with convex bottoms were used for storing food. Surface decorations on the pots include cockleshell and comb impressions, and applique.

Chipped stone tools were made from flint and quartz crystals brought from outside the area. Tools include sickles, piercers and scrapers made of microliths set into the handles of bone or antler. Groundstone adzes have been identified, as have small hand-operated mills for grinding grain.

Personal ornaments carved out of shell or animal teeth include beads, rings and bracelets. Numerous baskets made of twined sedges and rushes and reinforced by hazel branches were also found.

Excavations at La Draga

La Draga was discovered in 1990, and excavations have continued since then with the support of the Museu Arqueològic Comarcal de Banyoles (MACB) and the Centre d’Investigacions Subaquàtiques de Catalunya (CASC) and under the direction of Àngel Bosch, Júlia Chinchilla and Josep Tarrús (MACB) and Xavier Nieto, Xim Raurich and Antoni Palomo (CASC).

Luminescence Dating
Nov 17th 2011, 10:02

Definition:

Luminescence dating is a relatively new method of dating archaeological sites and materials. Although the best known form of luminescence dating is thermoluminescence (or TL), there are several scientific methods which can specify the date of certain artifacts or soil sediments by measuring the amount of light energy they have trapped in the mineral's crystals.

To put it simply, certain minerals (quartz, feldspar, and calcite), store energy from the sun at a known rate. This energy is lodged in the imperfect lattices of the mineral's crystals. Heating these crystals (such as when a pottery vessel is fired or when rocks are heated) empties the stored energy, after which time the mineral begins absorbing energy again.

TL dating is a matter of comparing the energy stored in a crystal to what "ought" to be there, thereby coming up with a date-of-last-heated. In the same way, more or less, OSL (optically stimulated luminescence) dating measures the last time an object was exposed to sunlight. Luminescence dating is good for between a few hundred to several hundred thousand years, making it much more useful than carbon dating.

Archaeology: What's Hot Now: Making Salt

Making Salt
Nov 17th 2011, 10:02

Salt (sodium chloride or NaCl) has a fairly unobtrusive appearance in our modern society. But its low cost and ready availability today hides a historical importance to many if not most civilizations in the past. Salt was a crucial component of many complex societies, and many ancient battles can be attributed to the fight over control of salt sources.

Why Make Salt?

Salt, a moderate amount of it anyway, is essential for human life: its presence in the human body maintains the balance of fluids that carry nutrients and oxygen from the digestive system to the other parts of the body. Its chemistry controls our taste, smell and touch; it enables the transmission of nerve impulses from the brain; and it preserves the acid / base balance in the body as well. A long string of scientific studies shows that an excessive intake of salt is tied to high blood pressure and concomitant health issues, but people still crave it. None of this is what drove our ancestors to gain and fight for secure access to salt.

The primary attraction of salt in history and prehistory is its use as a preservative. The application of salt to organic material absorbs moisture, inhibiting the growth of bacteria and mold. That fact allowed societies to mass produce food and store it for lean times--a crucial piece of social engineering that made long-term survival through winters and droughts a possibility.

Salt is also used to tan leather and in dying cloth; and it was also used in many societies to preserve human remains after death--the most famous example is natron, a geological salt used by the Egyptians to mummify their pharaohs.

Salt Making as a Process

The two main methods of salt production are mining and extracting. Societies which rose near a body of saline water, particularly near the coastlines of any of our oceans, could extract salt from seawater or salt-enriched plants by the application of heat or exposure to the sun. Inland societies sought and fought for the right to mine geologically ancient salt deposits. Alternatively, they could establish trade networks or capture and rule over the salt-producing areas of the coasts or inland salt sources.

We don't really know exactly when active salt production from sea water began. A good bet though, is that salt production on a large scale could not have happened prior to the invention of ceramics (~15,000 years ago).

Salt extraction followed a standard procedure, no matter where or when the process was completed. Brine was collected and poured into large coarse ceramic containers; the containers were then placed over fires. The brine would have been boiled down to form a soft paste, or simply been allowed to concentrate and then be transferred to small pots which were then set aside to evaporate and cool. Once salt crystallization had occurred, the small pots were broken apart to obtain a hard, nearly weightless, easily transportable cake.

Ceramic pots used for making salt are remarkably similar, with nearly identical pot forms used in salt production sites throughout the world. Also similar across the world is the archaeological evidence left by salt production: ash, structural remains and briquetage middens. Briquetage is the word for the midden deposits created by the breakage of massive numbers of ceramic pots.

In coastal areas, salt production from seawater likely began as a craft specialization, with households producing their own salt, and, perhaps to trade after the producer's essential needs were met, or the support of elites allowed. A typical household-level production site has been identified at the Sigatoka Sand Dunes in Fiji. Trade from larger, more complex salt production activities dates at least to the Neolithic period of about 4500 years ago, at sites such as the Beaker period Molino Sanchón II, in Spain (~2000-2500 cal BC) and the Longshan and Shang dynasty Zhongba site in China (2500-1800 BC).

Bent Pyramid (Egypt)
Nov 17th 2011, 10:02

Definition:

The Bent Pyramid is one of the Old Kingdom Pyramids at Giza, Egypt; built in the 4th Dynasty, 2680-2565 B.C. for the 4th dynasty pharaoh, Sneferu.

The pyramid is called "bent" because it changes angles at about 2/3 of the way to the top. To be precise, the lower 165 feet of the pyramid's shape is angled at 54 degrees, 31 minutes, at which point it abruptly flattens out to 43 degrees, 21 minutes.

Sneferu began his pyramid, but far too steeply, at an original angle of 60 degrees, and intended it to go to over 400 feet in height. John Romer speculates that while men were working inside the pyramid, ominous groans and cracks began to be heard. They stopped work on it, and built the Red Pyramid before returning to the Bent Pyramid, buttressing up its lower courses and adding the crown.

The Temples of Malta - A Photo Essay
Nov 16th 2011, 10:56

Malta and its smaller colleague Gozo are tiny islands in the Mediterranean Sea, 150 miles from Europe, 180 miles from North Africa and 90 miles from its nearest neighbor, Sicily. The first settlers arrived here some 8,000 years ago. but they were pretty much isolated, except for some trade off and on. Beginning about 6,500 years ago, they began to build temples, very odd and interesting temples, well worth a photo essay.

While the Malta temples are not the oldest in the world--that title probably goes to Gobekli Tepe in Turkey, some 11,000 years ago (and I say probably, because there is some debate about how you define "temple"), the Malta temples are interesting for a number of reasons, which I hope are illuminated in my photo essay, The Temples of Malta.

Camels
Nov 16th 2011, 10:02

Definition:

There are two species of quadruped animal of the deserts of the world known as camel, both of which have implications for archaeology. The Bactrian (Camelus bactrianus) (two humps) resides in central Asia, while the dromedary (Camelus dromedarius) (one hump) is found in North Africa and the Near East. Camels were (and are) used for transportation, but also for their milk, dung, hair and blood, all of which were used for various purposes by nomadic pastoralists of the deserts.

Dromedaries were probably domesticated in coastal settlements along the southern Arabian peninsula somewhere between 3000 and 2500 BC. The earliest reference to camels in Arabia is the Sihi mandible, a camelid bone direct dated to ca 7100-7200 cal BC, or about 8200 RCYBP. Sihi is a Neolithic coastal site in Yemen, and the bone is probably a wild dromedary. The earliest camels in Africa are from Qasr Ibrim, Nubia, 9th century BC.

Evidence for the domestication of Bactrian camels has been found as early as 2600 BC at Shar-i Sokhta (also known as the Burnt City), Iran.

Bog Bodies
Nov 16th 2011, 10:02

Definition:

The term bog bodies (or bog people) is used to refer to human burials, some likely sacrificed, placed within peat bogs of Denmark, Germany, Holland, Britain, and Ireland and naturally mummified. The highly acidic peat acts as a remarkable preservative, leaving the clothing and skin intact, and creating poignant and memorable images of people of the past.

The reason that bogs permit a high level of preservation is because they are both acidic and anaerobic (oxygen-poor). When a body is thrown into a bog, the cold water will hinder putrefaction and insect activity. Sphagnum mosses and the presence of tannin add to the preservation by having anti-bacterial properties.

The total number of bodies pulled from European bogs is unknown, partly because they were were first rediscovered in the 17th century and records are shaky. Estimates range wildly between about 200 to 700. The oldest bog body is Koelbjerg Woman, recovered from a peat bog in Denmark. the most recent dates to about 1000 AD. Most of the bodies were placed in the bogs during the European Iron Age and Roman period, between about 800 BC and AD 200.

Bog Bodies

Denmark: Grauballe Man, Tollund Man, Huldre Fen Woman, Egtved Girl, Trundholm Sun Chariot (not a body, but from a Danish bog all the same)

Germany: Kayhausen Boy

UK: Lindow Man

Ireland: Gallagh Man

Discovery of Fire
Nov 15th 2011, 10:23

The discovery of fire, or, more precisely, the controlled use of fire was, of necessity, one of the earliest of human discoveries. Fire's purposes are multiple, some of which are to add light and heat, to cook plants and animals, to clear forests for planting, to heat-treat stone for making stone tools, to burn clay for ceramic objects.

Discovery of Fire

The controlled use of fire was an invention of the Early Stone Age (or Lower Paleolithic). The earliest evidence for controlled use of fire is at the Lower Paleolithic site of Gesher Benot Ya'aqov in Israel, where charred wood and seeds were recovered from a site dated 790,000 years ago.

Not everybody believes that; the next oldest site is at Zhoukoudian, a Lower Paleolithic site in China dated to about 400,000 BP, and at Qesem Cave (Israel), between about 200,000-400,000 years ago.

In a paper published in Nature in March 2011, Roebroeks and Villa report their examinations of the available data for European sites and conclude that habitual use of fire wasn't part of the human (meaning early modern and Neanderthal both) suite of behaviors until ca. 300,000 to 400,000 years ago. They argue that the earlier sites are representative of opportunistic use of natural fires.

Hearth Fire Construction

As opposed to fire, a hearth is a deliberately constructed fireplace. The earliest fireplaces were made by collecting stones to contain the fire, or simply reusing the same location again and again and allowing the ash to act as hearth construct. Those are found in the Middle Paleolithic period (ca 200,000-40,000 years ago, at sites such as Klasies River Caves (South Africa, 125,000 years ago) and Tabun Cave (at Mt. Carmel, Israel)

Earth ovens, on the other hand, are hearths with banked and sometimes domed structures built of clay. These types of hearths were first used during the Upper Paleolithic (ca 40,000-20,000 years BP), for cooking, heating and, sometimes, to burn clay figurines to hardness. The Gravettian Dolni Vestonice site in the modern Czech Republic has evidence of kiln construction, although construction details did not survive. The best information on Upper Paleolithic kilns is from the Aurignacian deposits of Klisoura Cave in Greece (ca 32,000-34,000 years ago).

Fuels

Although relict wood may have been the original fuel, other sources became important in various places with limited wood supply. In places with scarce wood resources, timber and branch wood for structures, furnishing and tools would have cut back the amount used for fuel. If wood was not available, alternative fuels such as peat, cut turf, animal dung, animal bone, seaweed, and straw and hay. Techniques for discriminating fuel from ashy remains are outlined in the Church et al. paper listed below.

But of course, everyone knows that Prometheus stole fire from the gods, the Greek myth as reported by our Ancient History guide.
