Black Death


Using DNA taken from centuries-old skeletons, scientists have cracked the genetic code of the bacterium that caused the Black Death, one of history's worst plagues. They found that the germ, Yersinia pestis, is almost identical to germs that are around today.

There are only a few dozen changes among the more than 4 million building blocks of DNA, according to a study published online Wednesday in the journal Nature.

That suggests that the Black Death, or plague, was so lethal for reasons beyond its DNA, study authors said. It had to do with the circumstances of the world back then.

In its day, the disease killed 30 million to 50 million people - about 1 in 3 Europeans. It struck at a time when the climate was suddenly cooling, in the midst of war and famine, and people were moving into closer quarters where the disease could spread easily, scientists say. And it was likely the first time this particular disease had hit humans, suggesting that their immune defenses against the germ were lacking.

"It was literally like the four horseman of the apocalypse that rained on Europe," said study author Johannes Krause of Germany's University of Tubingen. "People literally thought it was the end of the world."

In devastating the population, Yersinia changed the human immune system, wiping out people who couldn't deal with the disease and leaving the stronger to survive, said study co-author Hendrik Poinar of McMaster University in Ontario.

Today, simple antibiotics like tetracycline can beat the plague bacterium, which seems to lack the properties that enable other germs to become drug resistant, Poinar said. Plus, advances in medical treatment, coupled with improved sanitation, put humanity in a better position. And there's an immune system protection we mostly have now, Poinar said.

"I think we're in a good state," Poinar said. "The reason we do so well is that conditions are so different."

People still get the disease, usually from fleas from rodents or other animals, but not often. Worldwide, there are around 2,000 cases a year, mostly in rural areas, with a handful popping up in remote parts of the U.S., according to the CDC. Earlier this year, two people in New Mexico were diagnosed with plague. In 1992, a Colorado veterinarian died from a more recent strain, one that scientists used heavily in their study.

Akrotiri

Many years ago, at the beginning of his career, a Greek archaeologist named Spyridon Marinatos was digging out a ruined Minoan villa at Amnissos, the ancient port of Knossos on Crete. The villa was once a beautiful mansion with a superb view of the sea, but there is wasn’t much to see when I visited. It is now mostly rubble, a foundation and a few crumbling walls.


The young Marinatos initially assumed an earthquake had wrecked the building. Every archeologist knew tremors plagued the Minoan empire. But when he unearthed a layer of pumice – which comes only from volcanoes – it occurred to him that volcanic activity was somehow involved. This was puzzling, because there is no Cretan volcano that might have deposited the pumice. After further studies, Marinatos published his theory that a volcanic eruption on the island of Thera, more than a hundred miles to the north, had destroyed the Amnissos villa, laid waste to the entire north coast of Crete and ruined the Minoan economy
.
At that time, in the 1930′s, leading archaeologists scoffed at his idea. Marinatos decided the best way to convince them was to excavate on Thera. If he could find Theran pottery of the same period as that of the destroyed palaces and villas in Crete, this would help to prove his theory.


Evidence of ancient habitation – potsherds, worked stone, and the like – had been unearthed near Akrotiri, a farming village at the southern end of Thera. However, no one bothered to investigate further. The village was ignored and local farmers and craftsmen went quietly about their work, as they had done for generations.

All that changed in 1967, when Marinatos – after decades of waiting – finally started digging for Minoan pottery. What he found was far greater than anything he had imagined. While pursuing small clues, Marinatos unearthed a Bronze Age city, well-preserved under six meters of volcanic ash. Akrotiri, whose name was given to the archeological site, suddenly became famous.



Entering the ancient city along the central boulevard, one can see the city as it was 3600 years ago. There are paved streets with a drainage system running under them, and flat-roofed stone buildings with wood framing that was engineered to withstand earthquakes. At the street level are workshops and stores, some of them with large ceramic storage jars (excavators found dried up food products in these). Above the shops are apartments where families lived comfortably with stylish furnishings in decorated rooms. Some homes even have indoor plumbing. Surprisingly, ancient Akrotiri looks very much like modern-day towns on Thera and other Aegean islands.


Walking these streets, one can begin to see how the inhabitants lived, and what sort of dealings they might have had with the Minoan empire on Crete – and with other countries as well. The most obvious clue is in the city itself. Wood was needed to erect houses, make furniture and tools, and (most importantly) build merchant ships that made the island rich. But prior to the great eruption, when the island was much larger than now, there were few trees. So where did Therans get enough wood to build cities and ships? They had to trade with others – Greece, Crete, Anatolia (Turkey), Cyprus, and Syria.

More clues are found in people’s homes. For example, some Akrotiri pottery is similar to Minoan wares, and it dates to the same period as the Cretan disaster (which supports the Marinatos volcano theory).


Other pottery styles indicate extensive trade. The colorful decoration technique used in many Theran vases did not develop locally. It is was copied from pottery of the East. There are even drinking vessels made from ostrich eggs, which suggests trade with Syria, Palestine and Egypt, where ostriches roamed wild.


This trade with eastern cultures also influenced Theran artwork. While the wall paintings in affluent Akrotiri homes maintain their own stylistic characteristics, strong Minoan and Egyptian influences are evident. The stylized wall paintings of ladies and papyrus plants from one house were like the Knossos frescos we saw on Crete. But curious differences suggest questions.


Does papyrus grow on Thera? No. It grows along the Nile River in Egypt. Why are people shown mostly in profile with a rigid stance, one leg placed firmly in front of the other? Many human images in Akrotiri are drawn according to the Egyptian Canon of Proportions, which was a religious art standard. This means each artist followed the same rules in depicting people, using a grid to ensure precision. The same proportions can be seen in the “fisherman fresco” found in another Akrotiri house.


This wall painting depicts a naked young fisherman carrying the day’s catch. Nudity is rare in Minoan art. Another unique feature is the fellow’s head, which appears to be shaved except for a few locks of hair, and painted blue. Some think it was a juvenile fashion, since only young people are shown with shaved heads. Others believe the style is religious and the fresco depicts an offering to the gods. Supporting a religious inference is the fact that the fisherman is walking towards a corner in the room where a table of offerings was found.


Pictures of animals, on the other hand, did not follow the same regulations, so artists had more freedom of expression. The famous “blue monkey” fresco is a good example. This seems to be an amusing composition of monkeys climbing a rocky hillside. These monkeys exude vitality and movement with their elongated, stylized bodies and wildly curvaceous tails. However, the painting also has religious significance, because monkeys were considered servants of the gods. It is believed the monkey motif originated in Crete or perhaps even Egypt, and later became popular on Thera. Artists in all these locations used blue coloring for the monkeys’ fur and skin.


The fresco of the antelopes diverges even more from Egyptian style. The antelopes are depicted using only black lines to define graceful legs, curved backs, long necks, and sharp horns. As a purely decorative painting, its beauty and simplicity is striking – and quite modern. Above the antelopes, a curving red-brown border reflects the curving backs and tails of the animals, creating a pleasant rhythm to the painting. Above that an ivy leaf frieze indicates springtime.


This painting reveals attention to form not seen in Egyptian art. Interestingly, although the antelope (Oryx beissa) is native to East Africa and is a popular subject in Egyptian art, the way it is depicted here reveals a uniquely Theran exuberance and love of beauty. While having integrated subject matter from a trading partner, this artist created a work entirely Theran in character – lively, fluid, and festive.

Minoan and Theran art seems to center on nature and the joys of living, but this focus is more enthusiastic at Akrotiri, where murals explode with color and movement. The clues found in this excavation make it clear that the people of Akrotiri were exposed to ideas and styles from many foreign lands. However, they managed to create their own unique identity.

UCLA Bridge

In May 1927, ground was broken at UCLA’s new Westwood campus and the first priority was to construct a bridge to cross the deep arroyo. Modeled in the Roman aqueduct style by University of California supervising architect George W. Kelham, the bridge was necessary for transporting construction supplies over the ravine that divided the east and west parts of the site.



In the summer of 1947, although the bridge was left in tact, the gully to its sides was filled. Today, the bridge’s arches remain hidden underground at Dickson Plaza.


The top sign is the only reference to the UCLA Bridge that remains. Most students do not realize that there is a bridge buried below the road.

Antinous

Antinous was born to a Greek family in the Roman province of Bithynia in what is now north-west Turkey, and joined the entourage of the emperor Hadrian at a young age, although nothing certain is known of how, when, or where he and Hadrian met. He is constantly described and depicted as a beautiful boy and youth. The relationship is believed to have been sexual. The following busts are of Antinous and Hadrian:
Antinous drowned in The Nile in October 130. Whether this was an accident, murder or suicide remains an unresolved question. The death was presented as an accident, "but it was believed at the time that Antinous had been sacrificed or had sacrificed himself," and Hadrian "wept for him like a woman." Hadrian went through the process of deifying him soon afterwards, a process previously exclusively reserved for imperial family members rather than friends or lovers of non-Roman origin.

Apollo and Helios

If you ever want to get a headache, try to find the difference between Helios and Apollo. Helios (not Apollo) is the Greek God of the Sun and he rides his Sun chariot across the sky during the day. Even the Romans made this distinction Helios became Sol Invictus. Helios is the Greek word for the Sun. Apparently, the idea of equating Apollo with the Sun and riding the chariot came later in time.

Although I always knew both names, it never really bothered me that much. I just went back and re-read one of my favorite books as a child, D'Aulaires' Book of Greek Myths. I came across a paperback copy of this book while in the Getty bookstore, and I purchased it despite the ridiculously high price. (I just found the hardcover copy on Amazon and I will buy it.) D'Aulaires says that Helios is the God of the Sun (and has the chariot). It also says that Apollo was as "fair as the Sun, and he was to be the god of music, light and wisdom." D'Aulaires also says that Apollo was given a silver bow and a quiver of arrows. Apollo's arrows "were hard and piercing as the rays of the Sun." When discussing the myth were Helios allowed his son to drive the Sun chariot. The son couldn't control the chariot, and he died. D'Aulaires notes that Helios "grieved over his lost son, and he never again allowed anyone to drive his chariot except for Apollo, the god of light."

Rare statue of Hercules discovered in Northern Israel

A rare statue depicting the Roman god Hercules has been discovered during an excavation in the Jezeel Valley in the north of Israel. The white marble figure stands at 0.5 metres and is thought to have originally decorated an alcove in a Roman bathhouse. It has been dated to the second century AD and is said to be of exceptional quality. Dr Walid Atrash of the Israel Antiquities Authority said: "This statue is unusual because it is small. Most statues of gods from this period were life-size. This is something special." The demigod is depicted leaning on a club, draped with the skin of the Nemean lion that he slew in the first of his twelve labours.
When I saw that this statue and the one posted earlier, I thought that I had seen another statue of Hercules leaning over his club. I found that it is a common classic pose:

Hercules statue returning from Boston to Turkey

During excavations in 1980 in Perge town of the southern province of Antalya, Prof. Jale Inan unearthed lower part of demigod Hercules statue. Officials noticed that a similar statue was being exhibited in Boston. Experts examined the statue in Boston and found out that it was the half of the part in Turkey. Presumably, someone cut the top half of the statute off, and sold that to the Boston Museum. Turkey has been exerting efforts to get back the upper part of the statue since that date.

The upper part of a Hercules (Heracles) statue is returning from Boston to Turkey. Turkish Culture & Tourism Minister Ertugrul Gunay told A.A on Sunday that the upper part of Weary Hercules Statue was returning from the United States to Turkey by the plane of Turkish Prime Minister Recep Tayyip Erdogan.

Arch of Hadrian & Constantine

Hadrian's Arch (shown above) existed when the Emperor Constantine reigned. Constantine added to it as shown below:
The blue and green sections indicate parts added by Constantine's artisans to the then-existing Arch of Hadrian. The yellow sections show parts that were taken from other monuments and added to Hadrian's Arch to make "The Arch of Constantine."
One of the parts added by Constantine shows him with his troops:
The following frieze shows Constantine (his face seems to be missing) and his court:
Hadrian's Arch without the Constantine's additions would look something like this:

Emperors Justinian and Constantinople

This mosaic in the Hagia Sophia, Constantinople (532-7 AD) depicts Justinian (left) presenting model of church of Hagia Sophia to the baby Jesus and the Virgin Mary. Constantine to the right presents her with model of Constantinople. (Justinian looks older than in the Ravena mosaic.)

The Court of Emperor Justinian and Empress Theodora

These mosaics from Ravena, Italy show the royal court of the Emperor Justinian and his wife, Theodora:
We also have Christ in Heaven from the same church:

Archangel Michael and the War in Heaven

"Now war arose in heaven, Michael and his angels fighting against the dragon. And the dragon and his angels fought back, but he was defeated, and there was no longer any place for them in heaven. And the great dragon was thrown down, that ancient serpent, who is called the devil and Satan, the deceiver of the whole world – he was thrown down to the earth, and his angels were thrown down with him." Revelation 12:7-9
I had an icon like this over my bed when I was a child. (Mine was a little different.)

Mona Lisa of the Galilee

One of the most exquisite and well-preserved mosaics was unearthed inside a building referred to as the Roman villa in the ancient city of Sepphoris(Zippori) in Israel.

The mosaic depicts a captivating woman adorned with earrings and a laurel garland. Her gaze is riveting; in fact, it appears she looks directly at you from every corner of the room. This woman has been dubbed "the Mona Lisa of the Galilee", not because she resembles DaVinci's subject but rather because she seems to have the same quality of timelessness and of superb artistry. She even has the same faint hint of a smile.
