Ancient trading

"Joakim Wehlin of the University of Gothenburg and Gotland University has examined Bronze Age stone monuments that sit along Sweden’s Baltic Sea coasts. It had been thought that the monuments, which resemble stone ships, were used primarily as grave sites. Wehlin, however, thinks that they were used by maritime groups trading in metal objects. “It seems like the whole body was typically not buried in the ship, and some stone ships don’t even have graves in them. Instead, they sometimes show remains of other types of activities. So with the absence of the dead, the traces of the survivors tend to appear,” he explained. The monuments may have been used to mark ports, waterways leading inland, and potential meeting places." From http://www.archaeology.org/news/690-130322-sweden-stone-ships-bronze-age

Stone ship at Blomsholm

The stone ship at Blomsholm near Strömstad in Bohuslän measures more than 40 metres in length and consists of 49 large menhirs. The bow and stern are about 4 metres high. There are several other large megaliths in the area. According to http://en.wikipedia.org/wiki/Stone_ship

Lindholm Høje

"Lindholm Høje (Lindholm Hills, from the word for hill or mound) is a major Viking burial site and former settlement situated to the north of and overlooking the city of Aalborg in Denmark. The southern (lower) part of Lindholm Høje dates to 1000 – 1050 AD, the Viking Age, while the northern (higher) part is significantly earlier, dating back to the 5th century AD.[1] An unknown number of rocks were removed from the site over the centuries, many, for example, being broken up in the 19th century for use in building roads..."

Anundshög

Anundshög is a tumulus in Sweden. It has a diameter of 60 metres (200 ft) and is about 9 metres (30 ft) high, dated between the Bronze Age and the late Iron Age. A fireplace under it has been dated by radiocarbon dating to sometime between AD 210 and 540. Some historians have associated the mound with the legendary King Anund. http://en.wikipedia.org/wiki/Anundsh%C3%B6g

At the foot of the mound are 2 large stone ships placed end to end, 51 metres (167 ft) and 54 metres (177 ft) long. Two other stone ships are visible. The site was a thing-place and the ship settings may be associated with this function, according to Wikipedia.

Astrophile: Saturn's egg moon Methone is made of fluff - space - 17 May 2013 - New Scientist

"Out among Saturn's menagerie of moons, a shiny white egg rests in a nest of ice crystals.
Named Methone, this small, oval moon was seen in close-up for the first time last year by NASA's Cassini spacecraft. Methone is utterly unlike the other small balls of ice and rock that dot the solar system, which are deeply scarred by impacts. Instead it is smooth, with not a hill or pockmark in sight. Now astronomers may have a clue as to why: Methone is made of lightweight fluff."Astrophile: Saturn's egg moon Methone is made of fluff - space - 17 May 2013 - New Scientist

Deep Space Beacon

Pulsed gamma rays from the Vela pulsar from photons detected by Fermi's Large Area Telescope. The Vela pulsar is the brightest persistent source of gamma rays in the sky. The bluer colour in the latter part of the pulse indicates the presence of gamma rays with energies exceeding a billion electron volts (1 GeV). For comparison, visible light has energies between two and three electron volts. Red indicates gamma rays with energies less than 300 million electron volts (MeV); green, gamma rays between 300 MeV and 1 GeV; and blue shows gamma rays greater than 1 GeV. The image frame is 30 degrees across. The background, which shows diffuse gamma-ray emission from the Milky Way, is about 15 times brighter here than it actually is.

Caesar and Arles

Image processing of the Arles bust 

It was probably between 49 and 46 BC, when Caesar had close relationships with Arles that, according to the French archaeologist Luc Long, who found it in 2007 after struggling with poor visibility, strong currents and the catfishes of Rhone, the famous marble bust of Arles had been carved. This beautiful portrait, discovered in the depths of the right bank of the river near Arles, has been undoubtedly attributed by Long to Julius Caesar. Here we compare the Arles bust with some others and propose the application of image processing and multimodal biometric systems to the ancient artifact. ... More at SSRN

Dancing Men in Renaissance Painting May Be Native Americans

Dancing Men in Renaissance Painting May Be Native Americans
Friday, May 03, 2013
VATICAN CITY—While restoring a fresco painted in 1494 by Pinturicchio on the walls of the Vatican’s Borgia Apartments, Maria Pustka found small images of dancing men that may be the first Western depictions of Native Americans. “The Borgia Pope was interested in the New World, as were the great chancelleries of Europe. It is hard to believe that the papal court, especially under a Spanish pope, would have remained in the dark about what Columbus encountered,” wrote Antonio Paolucci, director of the Vatican Museums. That pope would eventually arbitrate the division of New World lands between Spain and Portugal.

Although we know that spring and summer will come eventually, we are still a far cry from rivaling the “Year Without a Summer.”  That year was 1816. It was near the end of the Little Ice Age, a period that began around 1350 AD. It was also in the middle of what became known as the Dalton Minimum, an unusual period of low solar activity named after English meteorologist John Dalton that lasted from 1790 to 1830...."

Caesar and Caesarion

Quello sguardo amaro: i volti di Cesare e Cesarione. Intervista a Paolo Moreno

24/01/2011 - UmbriaLeft, by Giovanni Corazzi

Giusto un anno fa, nella nostra Umbrialeft veniva pubblicato un articolo in cui si parlava di una grande mostra, iniziata allora da qualche settimana (ottobre 2009) nel centro francese di Arles (presso il Musée départemental Arles antique) e dedicata agli oggetti riemersi dal fiume Rodano (riva destra, all’altezza, appunto, della cittadina provenzale) nel corso di una ventennale campagna condotta dal Drassm, il dipartimento ministeriale francese delle ricerche archeologiche, subacquee e sottomarine, guidato da Luc Long. .. tra cui un bellissimo busto. .. il Long sin dall’inizio avesse proposto senza esitazioni il nome di Cesare per il busto riemerso. Tale attribuzione, sebbene confermata da studiosi di valore quali lo storico Christian Goudineau (un classico il suo saggio su Cesare e la Gallia) e l’esperto di iconografia cesariana Flemming Johansen (autore di un importante lavoro del 1967, revisionato vent’anni dopo, dedicato ai ritratti in marmo di Cesare), è stata inizialmente contestata da altri studiosi, che hanno pensato a un magistrato romano o a un notabile di Arles. Fin dall’annuncio della scoperta (maggio 2008) era intervenuto al dibattito uno dei più importanti archeologi italiani, Paolo Moreno, ... Il Moreno ha toccato la questione anche nel 2009, con l’interessante ed elegante volume Cleopatra Capitolina (Editinera), e lo scorso ottobre in una lezione tenuta a Torino in occasione del «FestivalStoria». I suoi interventi hanno fornito nuove indicazioni sul ritratto, inserendolo in un ampio contesto che abbraccia il tratto mediterraneo da Arles ad Alessandria e che parla di una famiglia tanto grande quanto sfortunata. Divengono, infatti, protagonisti anche la regina d’Egitto Cleopatra e il figlio da lei avuto con Cesare, Tolemeo XV Cesare, meglio noto come Cesarione. Questi, nato nel 47 a.C., venne associato al regno a soli tre anni per volontà della madre, che evidentemente nutriva per il piccolo grandi progetti. ...

Air curtains for Terracotta Warriors

"New system can shield national relics from damage by pollution. Even the Terracotta Warriors are feeling the effects of China's choking air pollution. Chinese scientists have found that the indoor environment where the Terracotta Warriors are housed could cause them to deteriorate, prompting some scientists to raise the idea of using air curtain technology to help control the environment in the pits."

So much so that in just a few years the gains in archaeology now equal the gains made from the past 100 years of using traditional methods, explains nuclear physicist and University of Wollongong visiting Professor Claudio Tuniz. Dr Tuniz, who began his career in the United States using physics to analyse moon rocks and meteorites, has spent almost two decades examining how advanced scientific technology in nuclear physics and X-rays can tell us more about palaeoanthropology and human evolution. ..."

Leonardo da Vinci and Amboise

http://en.wikipedia.org/wiki/Château_d'Amboise

 "The royal Château at Amboise is a château located in Amboise, in the Indre-et-Loire département of the Loire Valley in France. Confiscated by the monarchy in the 15th century, it became a favoured royal residence and was extensively rebuilt. 

...

King Francis I was raised at Amboise, which belonged to his mother, Louise of Savoy, and during the first few years of his reign the château reached the pinnacle of its glory. As a guest of the King, Leonardo da Vinci came to Château Amboise in December 1515 and lived and worked in the nearby Clos Lucé, connected to the château by an underground passage." 

In 1516, Francis I invited Leonardo da Vinci to Amboise and hosted him in the Clos Lucé, then called Château de Cloux. Leonardo arrived in Amboise with three of his famous paintings:  Mona Lisa, Sainte Anne, and Saint Jean Baptiste. Leonardo lived at the Clos Lucé for the last three years of his life. He died there on 2 May 1519.

On disposait aussi de compas se rapportant à la géométrie mais aussi au traçage des lignes d’écriture. ...

Chimu Surveying

An Ancient Surveying Equipment of Chimu
The Chimu lives in the pre-Columbian Peru, struggling to survive in one of the world's driest desert.

They were therefore "hydraulic engineers". Some of their knowledge about the management of water came from their predecessors, the Mochica, who lived in the Peru's Moche Valley during the 1st millennium AD. Mochica built a network of canals to irrigate their fields. 

 Adapted from http://www.specialtyinterests.net/eop.html

This is a Chimu surveying instrument shows how calculate the slope of the land. "The device consisted of a ceramic bowl pierced by a hollow sighting tube passing through a calibrated, cross-shaped opening (inset). And artificial horizon was established by aligning water with the three dots in the bowl, which was leveled in a larger, sand-filled vessel atop a tripod (far left); when the sighting tube was in the center of the cross-shaped opening it was parallel to the artificial horizon. Chimu surveyors marked a rod at the height of the level sighting tube, then moved the rod a known distance along uneven ground and sighted the mark. The ground slope corresponded to the tube angle indicated by the calibrations inside the bowl." From

Surveying and Hydraulic Engineering of the Pre-Columbian Chimú State: ad 900–1450, Charles R. Ortloff, Cambridge Archaeological Journal, Volume 5 / Issue 01 / April 1995, pp 55-74
Abstract The Chimú state of northern coastal Peru (ad 900–1480) developed massive irrigation-based agricultural systems supplied by intricate networks of canals drawing water from river sources in coastal valleys under their political control. Further intervalley canal systems, some up to 50 miles in length, were constructed to shunt water between river valleys to augment intravalley supplies. A high degree of civil engineering skill was necessary to construct and maintain such complex systems; knowledge of surveying and of open channel flow hydraulics was paramount. Some of the technology used by the Chimú has been investigated: surveying instruments and calculating tools have been unearthed and analyzed to provide some understanding of the technical base used for canal design. Details of the hydraulics knowledge-base have been extracted from computer simulation of the functioning of ancient Chimú canal designs. This article assembles known pieces of information related to Chimú civil engineering practice and attempts to provide a plausible methodology that could have been implemented by the Chimú to survey the precise canal bed slopes necessary for proper hydraulic functioning of large canal systems through rugged Andean foothill and mountain areas.

Roman Dodecahedron of Kadath

The web site http://www.kadath.be/ is publishing the review Kadath. The site tells that it is based on the "projet KADATH". "Dans l’œuvre de H.P. Lovecraft, Kadath est la cité légendaire des Grands Anciens, symbole de l’origine des civilisations. Notre quête, appliquée aux réalités archéologiques, est de remonter à pareilles sources, en cherchant à déchiffrer l’empreinte que laissèrent les premiers civilisateurs, dieux et ancêtres présents dans tous les mythes et toutes les traditions."

Cooking ... the brain

"Brains demand exceptional amounts of energy," says Ed Yong at Discover Magazine — energy that raw food simply can't provide. That's where cooking comes in.
Writes Yong:
Our ancestors overcame this constraint when they learned how to cook. Cooked food offers more calories than raw food, and is easier to chew and digest. These early chefs could gain more energy from the same amount of eating time. That, in turn, fueled more neurons and larger brains.
