The Grooved Spheres 2. Giant Stone Balls of Costa Rica Workmen hacking and burning their way through the dense jungle of Costa Rica to clear an area for banana plantations in the s stumbled upon some incredible objects: They varied in size from as small as a tennis ball to an astonishing 8 feet in diameter and weighing 16 tons! Although the great stone balls are clearly man-made, it is unknown who made them, for what purpose and, most puzzling, how they achieved such spherical precision. Impossible Fossils Fossils, as we learned in grade school, appear in rocks that were formed many thousands of years ago. A fossil of a human handprint, for example, was found in limestone estimated to be million years old. What appears to be a fossilized human finger found in the Canadian Arctic also dates back to million years ago. And what appears to be the fossil of a human footprint, possibly wearing a sandal, was found near Delta, Utah in a shale deposit estimated to be million to million years old.
Although the dividing line between the Lower and Middle stages is not so clearly defined as that separating the Middle and Upper subdivisions, this system is still used by most workers. Lower Paleolithic On the basis of the very rich materials from the Somme Valley in the north of France and the Thames Valley in the south of England, two main Lower Paleolithic traditons have been recognized in western Europe. These are as follows: The type tools of the Abbevillian formerly Chellean , which takes its name from the town of Abbeville, France, on the metre foot terrace of the Somme Valley, consist of pointed, bifacial implements, or hand axes.
Their forms vary, and the flaking is generally irregular; it is probable that they were manufactured either with a stone hammer or on a stone anvil. Associated with these crude types of hand axes, simple flake tools are found, but they lack definite form.
Other Viking Artifacts in North America. There are a small group of Norse artifacts found in North America that are widely regarded as genuine. These include the artifacts found at L’Anse aux Meadows (left) and the 11 th century Norwegian coin found in Maine in (right).. In addition, there are a large number of artifacts not widely accepted as genuine.
An approach to systematically evaluate possible flakes is explicated. Abstract Archaeologists have long struggled with distinguishing lithic materials modified by humans artifacts from natural objects e. This problem is especially difficult for finds of small numbers of flake-like lithic specimens, and particularly for very old finds. We attempt to address the artifact versus geofact problem at a paleontology site by employing three systematic and objective tests on the two recovered possible artifacts.
First, they are compared with debitage attributes typically expected of artifacts and geofacts based on published experimental and actualistic data. Second, they are compared in terms of nine of these attributes with a toolstone sample from the site excavation matrix. Third, the two possible artifacts are scored for these nine attributes and graphed against the toolstone matrix sample and two samples of flintknapped debitage assemblages. In all three comparisons, the two specimens are more like artifacts than geofacts.
Top 10 unexplained ancient artifacts – Fact or Fiction?
Idealized representation of the Bay of Alexandria. Founded by Greek general Alexander the Great in BC, at its height it rivalled Rome in its wealth and size, and was the seat for the Ptolemaic dynasty. However, through history not all agreed on how to regard the Hellenistic city with a royal Egyptian past. An underwater temple discovered by marine divers off the eastern coast shed light on the pharaonic nature of ancient Alexandria. As previously reported in Ancient Origins , Ptolemaic Alexandria has been regarded, in academic circles, not as part of Egypt, but as a separate Greek polis, or city-state, by the borders of Egypt.

One of these monuments marks the precise location of Leif’s house in Cambridge, near the banks of the Charles River. How do we know the location of Leif’s travels so precisely? The simple answer is that we do not. However, at the end of the 19th century, Eben Norton Horsford, a professor of chemistry at Harvard, felt that he had proof of Norse settlements in several towns along the Charles. Horsford wrote extensively about his findings and had a hand in the creation of the various monuments.
During his life, Prof. Horsford made a fortune through the commercialization of his chemical processes, notably, his process for making baking powder left.

The intelligent reader will judge for himself. Without examining the facts fully and fairly, there is no way of knowing whether vox populi is really vox dei, or merely vox asinorum. — Cyrus H. Gordon Voynich Manuscript Written in Central Europe at the end of the 15th .
The development of the process was likely initiated as glass blowers experimented with molds as a way of producing special surface effects on their vessels. For instance, with pattern molding, the parison was initially shaped inside a mold that had been sculpted with diamonds, facets, circles, etc.. The mold would impart these designs to the body of the vessel. Typically the process was completed by removing the parison from the mold and blowing and spinning it in an off-hand fashion until the desired shape and size were achieved.
The second step in the transition to molding involved the use of what are known as dip molds. In this circumstance, the size and shape of the parison was complete when it was removed from the mold. In the case of round bottles, the mold was simply a cylinder, open at one end, within which the glass blower blew his bubble. This application of the mold allowed for a new style of patterning – embossed product names and logos.
The third step in the transition to fully automated molding was the use of molds consisting of multiple parts. This type of mold always left ridges or seams of glass where the sections of the mold joined together.
Creation vs. Evolution
One might expect that the first examples of art would be simple and crude. However the oldest cave paintings are the evidence that modern humans were astonishingly quick in developing their artistic skills. Ancient Cave Paintings Cave paintings are paintings found on cave walls and ceilings, and especially refer to those of prehistoric origin. The earliest such art in Europe dates back to the Aurignacian period, approximately 40, years ago, and is found in the El Castillo cave in Cantabria, Spain.
As we move on down the line of the 10 most not-so-puzzling ancient artifacts, we come to the Ica Stones. These are perhaps the most perplexing to me, since I don’t understand how anyone can look at these and think they are real. These little gems range in size from cobbles to boulders, and depict a wide variety of images.
His position as curator of the museum gave him enough visibility to become highly influential on Danish archaeology. A well-known and well-liked figure, he explained his system in person to visitors at the museum, many of them professional archaeologists. They were terrible and strong, and the ghastly action of Ares was theirs, and violence. The weapons of these men were bronze, of bronze their houses, and they worked as bronzesmiths.
There was not yet any black iron. Hesiod knew from the traditional poetry, such as the Iliad , and the heirloom bronze artifacts that abounded in Greek society, that before the use of iron to make tools and weapons, bronze had been the preferred material and iron was not smelted at all. He did not continue the manufacturing metaphor, but mixed his metaphors, switching over to the market value of each metal. Iron was cheaper than bronze, so there must have been a golden and a silver age.
He portrays a sequence of metallic ages, but it is a degradation rather than a progression. Each age has less of a moral value than the preceding. Lucretius , however, replaced moral degradation with the concept of progress,  which he conceived to be like the growth of an individual human being. The concept is evolutionary:

Over the last 40 years, there has been a discernible increase in the number of scholars who have focused their research on early industrial organizations, a field of study that has come to be known as Archaeotechnology. Archaeologists have conducted fieldwork geared to the study of ancient technologies in a cultural context and have drawn on the laboratory analyses developed by materials scientists as one portion of their interpretive program.
Corroded iron from the Java Sea Wreck. Chinese Warring States arrowhead dating to about — B. A wrought-iron Roman cleaver. Large spear from Burkino Faso, Africa. Paperweight made by reworking iron from the Himeji Castle in Japan. In this article, an overview is presented of the status of the radiocarbon dating of iron-based materials. Recent advances include simplification in sample preparation and reduction in sample size for accelerator mass spectrometry measurements, and the potential use of rust as a viable source of material for radiocarbon dating.
Additionally, a summary is presented of all 63 previously published results for iron-based materials and 29 new results that have not been published previously. These materials range from low-carbon wrought irons to medium to very high-carbon steels and cast irons. Artifact dates range from several hundred years ago to several thousand years ago.

Although more expensive than radiometric dating, AMS dating has higher precision and needs small sample sizes. Aside from archaeology and geology, AMS dating is also used in other fields like biomedical research and ocean sciences research. There are two techniques in measuring radiocarbon in samples—through radiometric dating and by Accelerator Mass Spectrometry AMS.
Amino Acid Dating Introduction. Amino acid dating has an important attribute in common with Carbon 14 dating. While most other dating mechanisms date the rock surrounding fossils, both Amino Acid and Carbon 14 dating methods, date the actual fossil itself.

Origins[ edit ] The Shakers were one of a few religious groups formed in 18th century in the Northwest of England ;  originating out of the Wardley Society. James and Jane Wardley and others broke off from the Quakers in   at a time when the Quakers were weaning themselves away from frenetic spiritual expression. Their belief was based upon spiritualism and included the notion that they received messages from the spirit of God which were expressed during religious revivals.
They also experienced what they interpreted as messages from God during silent meditations and became known as “Shaking Quakers” because of the ecstatic nature of their worship services. They believed in the renunciation of sinful acts and that the end of the world was near. For the kingdom of God is at hand. The new heaven and new earth prophesied of old is about to come. The marriage of the Lamb, the first resurrection, the new Jerusalem descended from above, these are even now at the door.
And when Christ appears again, and the true church rises in full and transcendent glory, then all anti-Christian denominations—the priests, the Church, the pope—will be swept away. As their numbers grew, members began to be persecuted,  mobbed, and stoned; Lee was imprisoned in Manchester.
