Cleopatra's likeness was pieced together from images on ancient artifacts, including a ring dating from Cleopatra’s reign 2,000 years ago, and the remains of her sister Princess Arsinöe found in 2009
~~Ancient Egypt’s stunning eye make-up not only shielded wearers from the dark deeds of the evil eye but also protected them against eye disease, French scientists said Thursday.
Ancient Egyptians some 4,000 years ago produced the make-up used to darken and adorn eyes with lead and lead salts in mixtures that sometimes took a month to concoct, said Philippe Walter, who co-headed a team of scientists from the Louvre Museum
and the (CNRS) National Center of Scientific Research
“We knew ancient Greeks and Romans too had noted the make-up had medicinal properties, but wanted to determine exactly how,” he told AFP.
Contrary to widely held belief that lead is harmful, the team, using analytical chemistry, determined that “in very low doses lead does not kill cells.”
Curator Sally-Ann Ashton admires one of the statues of Cleopatra at the British Museum in London.
Instead, it produces a molecule — nitric oxide — that activates the immune defense system which beats back bacteria in case of eye infection.
The research was carried out using a tiny electrode, the 10th of the size of a hair, to look at the effect of a lead chloride synthesized by the Egyptians — laurionite — on a single cell.

‘Bluestonehenge‘ found by archaeologists less than two miles from world-famous prehistoric monument
Guardian.co,UK/James Sturcke & Maev Kennedy —Archaeologists have discovered evidence of what they believe was a second Stonehenge located a little more than a mile away from the world-famous prehistoric monument.
The new find on the west bank of the river Avon has been called “Bluestonehenge“, after the colour of the 25 Welsh stones of which it was once made up.
Excavations at the site have suggested there was once a stone circle 10 metres in diameter and surrounded by a henge – a ditch with an external bank, according to the project director, Professor Mike Parker Pearson, of the University of Sheffield.

The stones at the site were removed thousands of years ago but the sizes of the holes in which they stood indicate that this was a circle of bluestones, brought from the Preseli mountains of Wales, 150 miles away.
The standing stones marked the end of the avenue that leads from the river Avon to Stonehenge, a 1¾-mile long processional route constructed at the end of the Stone Age.
The outer henge around the stones was built about 2400BC but arrowheads found in the stone circle indicate the stones were put up as much as 500 years earlier.
Parker Pearson said his team was waiting for results of radiocarbon dating which could reveal whether stones currently in the inner circle of Stonehenge were originally located at the other riverside construction.
