Shah Jahan commissioned a jewel encrusted gold throne to be built on a pedestal in the courtroom, where he could then be seated above the crowd, closer to God. Among the hundreds of rubies, emeralds, pearls, and other jewels embedded in the Peacock Throne was the famed 186-carat Koh-i-Noor diamond, which was later taken by the British.

1739, when Nader Shah of Persia sacked Delhi and stole the Peacock Throne.

experts believe that the legs of the 1836 Qajar Throne, which was also called the Peacock Throne, might have been taken from the Mughal original.

Recent experiments suggest that XBB paid a steep price for its power to evade immunity. The mutations allow it to escape antibodies by altering the shape of the protein, called spike, that covers its surface. But some of those mutations also make it harder for XBB spike proteins to grab tightly to cells — the first step required for an infection.

That loose grip may have lessened XBB’s advantage against other forms of the virus. In late 2022, it jostled alongside a number of other Omicron subvariants. In Singapore, XBB caused a surge in October, for example, while remaining rare in many other parts of the world.

As XBB multiplied, it continued to mutate into new forms. The earliest samples of XBB.1.5 were isolated in October in New York. The new subvariant gained one crucial mutation, known as F486P.

Yunlong Cao of Peking University and his colleagues tested out XBB.1.5 in dishes of cells, comparing how it fared against earlier forms of XBB. The researchers found that the F486P mutation allowed XBB.1.5 to grab tightly to cells again. But the new subvariant could still evade antibodies as well as earlier forms of XBB.

In Connecticut, for example, Nathan Grubaugh at Yale University and his colleagues found that by mid-December, other Omicron subvariants were falling. Only XBB.1.5 cases were growing. Dr. Grubaugh estimates that it is about 20 percent more transmissible than BQ.1, which had been the dominant form.

How severe XBB.1.5 infections are compared with other forms of the coronavirus is not yet clear. “It’s serious,” Dr. Grubaugh said. “I just don’t necessarily know if it’s really more serious than some of the other Omicron lineages in terms of the overall impact.”

XBB.1.5 has already spread to other countries, and is growing rapidly in Germany, Denmark and elsewhere in Europe

Scientists are already scanning new sequences being uploaded to an international database called GISAID in the hopes of spotting an upgraded version of XBB.1.5. But their job is getting harder because governments are pulling back on sequencing efforts. “Worldwide, sequencing has taken a real hit,” Dr. Peacock said.

The United States, which once lagged behind other nations, has managed to maintain a fairly strong sequencing effort. Without it, Dr. Peacock said, XBB.1.5 might have stayed below the radar for much longer. If XBB.1.5’s next generation is evolving somewhere with little sequencing, it may go undetected for some time to come.

Dr. Lemieux said that paring back on sequencing was a mistake, given how many infections and deaths the virus is still causing. “This is a part of public health,” he said.

In his essential recent book Reckless Opportunists, Aeron Davis charts the breadth and the depth of this betrayal. The sociologist has spent two decades interviewing more than 350 people at the top of Westminster and Whitehall, big business, the media and the City.

Across these interlocking elites, he finds common trends: they reach the top far sooner, stay in post for far less time, before rushing through the revolving doors to the next gig.

The result, Davis writes, is a generation of leaders who are “precarious, rootless and increasingly self-serving”. They grab whatever they can – be that cheap headlines or fast money – and then crash out, even while loosening the very foundations of the institutions entrusted to them

one of the strongest lessons of this period is that we need a wholesale reimagining of our institutions so that they better serve the rest of us, rather than just those who run them

ohn Redwood. The arch-Brexiter and Thatcherite MP has a side-gig in the finance industry (or perhaps it is the other way round) and observed here what a tonic populism had proved for markets

Redwood wrote: “A bit of populism might be no bad thing when I look at the state of the euro area economy.” By “a bit of populism” the MP for Wokingham presumably means the Mussolini-worship and xenophobia of Italy’s Matteo Salvini. And Hungary’s prime minister, Viktor Orbán, silencing the media and driving judges into retirement, behaviour that has earned him unprecedented sanctions from the European parliament. Chaos and authoritarianism are fine, it appears, as long as they prove good for asset prices

He has been castrated at the age of six by the leader of a rival tribe, so he had no sons, but his nephew Fath Ali Shah Qajar succeeded him as Shahanshah, or "King of Kings."

Earlier in his reign, Nasser al-Din had sought to regain Persian prestige after the loss of the Caucasus by invading Afghanistan and attempting to seize the border city of Herat. The British considered this 1856 invasion a threat to the British Raj in India, and declared war on Persia, which withdrew its claim.

Also in 1907, Britain and Russia carved Persia into spheres of influence in the Anglo-Russian Agreement of 1907.

Although Aurangzeb had a lot of success in extending Mughal rule north and westward, in 1652, he failed to take the city of Kandahar (Afghanistan) from the Safavids.

The 15-year-old Aurangzeb proved his courage in 1633. All of Shah Jahan's court was arrayed in a pavilion, watching an elephant fight when one of the elephants ran out of control. As it thundered towards the royal family, everyone scattered - except Aurangzeb, who ran forward and headed off the furious pachyderm.

This act of near-suicidal bravery raised Aurangzeb's status in the family.

When Aurangzeb's sister died in a fire in 1644, he took three weeks to return home to Agra rather than rushing back immediately. Shah Jahan was so angry about his tardiness that he stripped Aurangzeb of the Viceroyalty of Deccan.

Relations between the two deteriorated the following year, and Aurangzeb was banished from court.

Shah Jahan needed all of his sons in order to run his huge empire, however, so in 1646, he appointed Aurangzeb Governor of Gujarat.

The prince revolted against his father but was defeated after four years. Aurangzeb and a brother were sent to their grandfather's court as hostages.

As his condition worsened, his four sons by Mumtaz began to fight for the Peacock Throne.

Shah Jahan favored Dara, the eldest son, but many Muslims considered him too worldly and irreligious. Shuja, the second son, was a complete hedonist, who used his position as Governor of Bengal as a platform for acquiring beautiful women and wine. Aurangzeb, a much more committed Muslim than either of the elder brothers, saw his chance to rally the faithful behind his own banner.

Aurangzeb craftily recruited his younger brother, Murad, convincing him that together they could remove Dara and Shuja, and place Murad on the throne. Aurangzeb disavowed any plans to rule himself, claiming that his only ambition was to make the hajj to Mecca.

Aurangzeb had his former ally Murad executed on trumped-up murder charges in 1661

Aurangzeb's 48-year reign is often cited as a "Golden Age" of the Mughal Empire, but it was rife with trouble and rebellions. Although Mughal rulers from Akbar the Great through Shah Jahan practiced a remarkable degree of religious tolerance and were great patrons of the arts, Aurangzeb reversed both of these policies. He practiced a much more orthodox, even fundamentalist version of Islam, going so far as to outlaw music and other performances in 1668.

Both Muslims and Hindus were forbidden to sing, play musical instruments or to dance - a serious damper on the traditions of both faiths in India.

Aurangzeb also ordered the destruction of Hindu temples, although the exact number is not known. Estimates range from under 100 to tens of thousands. In addition, he ordered the enslavement of Christian missionaries.

Aurangzeb expanded Mughal rule both north and south, but his constant military campaigns and religious intolerance rankled many of his subjects. He did not hesitate to torture and kill prisoners of war, political prisoners, and anyone he considered un-Islamic. To make matters worse, the empire became over-extended, and Aurangzeb imposed ever higher taxes in order to pay for his wars.

Perhaps the most disastrous revolt of all was the Pashtun Rebellion of 1672-74. The founder of the Mughal Dynasty, Babur, came from Afghanistan to conquer India, and the family had always relied upon the fierce Pashtun tribesmen of Afghanistan and what is now Pakistan to secure the northern borderlands. Charges that a Mughal governor was molesting tribal women sparked a revolt among the Pashtuns, which led to a complete breakdown of control over the northern tier of the empire and its critical trade routes.

The objects and structural remnants on display in the museum paint a vivid picture of wealth, power and opulence. Among the stunning examples of ancient Roman artistry are elaborate mosaics and frescoes, a marble staircase, capitals of colored marble and limestone, and an imperial guard’s bronze brooch inset with gold and mother-of-pearl. “All the most refined objects and art produced in the Imperial Age turned up,” Dr. Serlorenzi said.

“The frescoes are incredibly ornate and of a very high decorative standard,”

“Given the descriptions of Caligula’s licentious lifestyle and appetite for luxury, we might have expected the designs to be quite gauche.”

Evidence suggests that after Caligula’s violent death — he was hacked to bits by his bodyguards — the house and garden survived at least until the Severan dynasty, which ruled from A.D. 193 to 235. By the fourth century, the gardens had apparently fallen into desuetude, and statuary in the abandoned pavilions was broken into pieces to build the foundations of a series of spas. The statues were not discovered until 1874, three years after Rome was made the capital of the newly unified Kingdom of Italy.

The latest excavation of the horti unfolded under the detritus of the residences, which had been evacuated in the 1970s in the wake of a building collapse.

I doubt these new discoveries will do much to rehabilitate his character. But they should open up new vistas onto his world, and reveal it to be every bit as paradisiacal as he desired it to be.”

Then there’s Elagabulus, whose biography is a veritable catalog of extreme pranks. He taunted his guests by serving them platters of faux food made from wax or wood or marble, while he feasted on real delicacies. Sometimes he served his guests paintings of meals, or napkins embroidered with pictures of the food he was eating. (Imagine walking away from a dinner with an empty stomach but loaded down with paintings of a Roman feast: flamingo tongues, peacock brains, combs cut from the heads of living roosters, etc.) Even when he served actual food, he delighted in mixing the edible and inedible, seasoning peas with gold nuggets, rice with pearls, and beans with glowing chips of amber.

Under Roman law, a slave was not considered to be properly a human being. But the “masters” must have known on some level that their “property” was not really theirs, that subservience and subordination were acts put on under duress. In theory, absolute power is invulnerable; in practice, the emperor is always looking over his shoulder for the assassins in the shadows

Until the 1930's, Antioch's remains were almost entirely literary; its physical glories had been obliterated by earthquakes, floods and invasions from the east.

Since then, however, as the study of history has focused as much on ordinary citizens as on their leaders, attention has shifted from throne rooms to dining rooms. Only 10 percent of Antioch's population was rich, according to the fourth-century pagan philosopher Libanios, and only 10 percent was poor. The remaining 80 percent lived remarkably well, and at its height, Antioch's population numbered more than 400,000 citizens and freedmen, not counting women, children and slaves.

The exhibition focuses on their dining rooms, or triclinia, in order to recreate the city's great middle-class era, and for middle-class America at the beginning of the third millennium, those ancient houses reveal a familiar ostentation.

Antioch: The Lost Ancient City'' reunites many of the artifacts and objects excavated by the expedition, including some of the most beautiful mosaics. During the five years of preparations for this show, scholars examined for the first time in decades some of the material from the excavations that had been in storage, and the show's catalog presents much of their new research.

Antioch marked the crossroads of trade routes between Persia and the Far East, Egypt and Rome.

During the centuries of the Roman peace, Antioch flourished; its baths and wide arcaded streets were theaters where strangers -- Romans, Syrians, Jews, Christians, Persians, Greeks -- mingled and learned from one another. Its dining rooms set a more intimate stage upon which to continue the dialogue.

The city's pivotal geography proved the source of both its vitality and its vulnerability. Persian emperors of the Sasanian dynasty coveted Antioch, sacked it twice -- in A.D. 256 and 540 -- and incorporated the phrase ''better than Antioch'' into the names of the cities they built closer to home. Sasanian stylized art, using birds and animals in patterned design -- a mosaic border of ram's heads, for instance -- found its way into Antioch's houses.

Probably they discussed religion. The Pax Romana, of course, has found its modern parallel in the Pax Americana, in the worldwide exportation of American culture. Ideas, art, politics and religions circulate, blend and clash. The yearning for a spiritual haven was perhaps even more urgent in Roman Antioch than it is today.

The expeditions of the 1930's dug up no pagan temples or synagogues, but they did uncover in Antioch's port remnants of a church whose ambulatory was paved with a mosaic of animals and birds. Elephants, flamingos, zebras, gazelles, peacocks, a lioness and her cubs: all creation circled the church in a docile parade.

In this floor, pagan entertainment translated into a vision from Genesis: the bloody staged hunt has been converted to a peaceable kingdom.

Authoritarian governments have created seemingly realistic news broadcasters to advance their political goals

Getty’s lawsuit reflects concerns raised by many individual artists — that A.I. companies are becoming a competitive threat by copying content they do not have permission to use.

“The tools are going to get better, they’re going to get cheaper, and there will come a day when nothing you see on the internet can be believed,” said Wasim Khaled, chief executive of Blackbird.AI, a company that helps clients fight disinformation.

Artificial intelligence allows virtually anyone to create complex artworks, like those now on exhibit at the Gagosian art gallery in New York, or lifelike images that blur the line between what is real and what is fiction. Plug in a text description, and the technology can produce a related image — no special skills required.

Midjourney’s images, he said, were able to pass muster in facial-recognition programs that Bellingcat uses to verify identities, typically of Russians who have committed crimes or other abuses. It’s not hard to imagine governments or other nefarious actors manufacturing images to harass or discredit their enemies.

In February, Getty accused Stability AI of illegally copying more than 12 million Getty photos, along with captions and metadata, to train the software behind its Stable Diffusion tool. In its lawsuit, Getty argued that Stable Diffusion diluted the value of the Getty watermark by incorporating it into images that ranged “from the bizarre to the grotesque.”

Experts fear the technology could hasten an erosion of trust in media, in government and in society. If any image can be manufactured — and manipulated — how can we believe anything we see?

Trademark violations have also become a concern: Artificially generated images have replicated NBC’s peacock logo, though with unintelligible letters, and shown Coca-Cola’s familiar curvy logo with extra O’s looped into the name.

The threat to photographers is fast outpacing the development of legal protections, said Mickey H. Osterreicher, general counsel for the National Press Photographers Association

Newsrooms will increasingly struggle to authenticate conten

Social media users are ignoring labels that clearly identify images as artificially generated, choosing to believe they are real photographs, he said.

The video explained that the deepfake had been created, with Ms. Schick’s consent, by the Dutch company Revel.ai and Truepic, a California company that is exploring broader digital content verification

The companies described their video, which features a stamp identifying it as computer-generated, as the “first digitally transparent deepfake.” The data is cryptographically sealed into the file; tampering with the image breaks the digital signature and prevents the credentials from appearing when using trusted software.

The companies hope the badge, which will come with a fee for commercial clients, will be adopted by other content creators to help create a standard of trust involving A.I. images.

“The scale of this problem is going to accelerate so rapidly that it’s going to drive consumer education very quickly,” said Jeff McGregor, chief executive of Truepic

Adobe unveiled its own image-generating product, Firefly, which will be trained using only images that were licensed or from its own stock or no longer under copyright. Dana Rao, the company’s chief trust officer, said on its website that the tool would automatically add content credentials — “like a nutrition label for imaging” — that identified how an image had been made. Adobe said it also planned to compensate contributors.
