US to return 297 antiquities to India
  + stars: | 2024-09-23 | by ( Chris Lau | ) edition.cnn.com   time to read: +2 min
CNN —The US is returning 297 history-spanning antiquities stolen or smuggled from India, many dating back centuries. In July, the US and India signed an agreement to protect cultural property by preventing illegal trades and streamline the process to return stolen antiquities back to India. “Prime Minister (Modi) thanked President Biden for his support in the return of these artifacts,” the India’s Ministry of External Affairs said. India has faced an uphill battle in protecting its valuable cultural treasures from looters, though it has been making headway in recent years. In 2022, the US returned 307 stolen treasures to India as part of a 15-year investigation into international trafficking networks.

AdvertisementThe basic ingredients for an ancient beerMax Miller relied on a hymn and expert research to try and create an ancient beer. To make his version, Miller used water, barley, barley flour, a sourdough starter, coriander, cardamom, date syrup, and brewer's yeast. Some experts aren't sure if ancient beer was even alcoholic at all. Ancient beer is different from today's alesDon't expect your hymn-inspired homebrew to resemble anything you can buy at the store. There's also no evidence that ancient beer makers used hops, which is a ubiquitous ingredient today.

Termessos, Turkey CNN —Alexander the Great tried to conquer Termessos but failed. He reputedly called the city an “eagle’s nest.”Later, the Romans had more success in controlling the city. Barry Neild/CNNClimbing higher up the hillside on a rocky path sprouting with fragrant wild sage, there’s more evidence of how sophisticated life in Termessos would’ve been. Further up, the upper city walls give commanding views of the forest below and offer a good vantage point over anyone trying to sneak up for an invasion. In Termessos, the location is particularly significant, as it sits opposite a mountain that was once sacred to the city’s inhabitants.

CNN —Australian police are seeking two people for allegedly vandalizing a century-old Chinese parade dragon and other valuable artefacts at a museum in a small town known for its historic links to China. The vandalism took place last week at the Golden Dragon Museum in Bendigo, about 100 miles northwest of Melbourne, according to the police and head of the museum. Golden Dragon MuseumBendigo, currently a city of some 100,000 people, has had Chinese residents for more than a century. To this day, a large dragon parade is held every Easter to raise money for a local hospital. The Golden Dragon Museum was opened in 1991 “to document, interpret and preserve the Chinese heritage in Australia” according to the museum’s website.

Less obviously visible but equally impressive are the historical treasures, some more than 12,000 years old, that can be found underground. Unlike the Basilica, this underground chamber was completely forgotten about until less than 15 years ago. Other than locals herding their livestock through the ruins of a garrison city dating to the 6th century, few people went there. Now, the site has given up numerous treasures including rock-cut tombs, an olive processing workshop and a series of underground cisterns. Yeraltı, literally meaning underground, was originally a dungeon in the basement of a fort built by the Byzantines in the 8th century CE.

CNN —Colorful paintings of daily life in ancient Egypt have been discovered in a tomb dating back more than 4,300 years. The tomb, known as a mastaba, was found in the pyramid necropolis of Dahshur, about 25 miles south of Cairo, during a recent Egyptian-German archaeological mission. The main attractions there are two large pyramids of King Sneferu: the so-called Bent Pyramid and the Red Pyramid. The daily life of the ancient Egyptians and their animals can be seen in the paintings. It added: “Cleaning and documentation work will be carried out on the tomb and its inscriptions during the coming period.”

It was July of 2022, and the co-founder of Discover Africa Safaris was out in the bush near the Khwai River in northern Botswana. African lions are fully capable of attacking, killing and even eating humans, and it’s generally estimated about 250 people a year die in lion attacks. WLDavies/E+/Getty ImagesOnly about 23,000 lions remain in sub-Saharan Africa, found mostly in Eastern and Southern Africa, Muruthi said. Before your trip, It's important to study up on safety tips -- such as remaining inside your safari vehicle when lions and other wild animals approach. Secondly, fleeing indicates to the lion you’re frightened and now possible prey, turning what might have initially been a mock charge to test you into a real attack.

CNN —Archaeologists working deep in the Amazon rainforest have discovered an extensive network of cities dating back 2,500 years. The team also discovered monumental complexes with much larger platforms, which, they said, probably had a civic or ceremonial function. Even the most isolated complexes were linked by pathways and an extensive network of larger, straight roads with curbs. In the empty buffer zones between complexes, the team found features of land cultivation, such as drainage fields and terraces. These were linked to a network of footpaths, according to the study.

The Adriatic coast is undeniably beautiful, with the forbidding Dinaric Alps as a dramatic backdrop to the heavily indented coastline and dozens of islands scattered about. Until 2022, reaching it from the north meant crossing into Bosnia, whose 12.4 miles of coastline sits below the Neretva delta, before giving way once more to Croatia’s southern Dalmatian coast.

According to Selvaraj's research, in humid areas of India, builders used local herbs that help structures deal with moisture. Even though Roman concrete lasted a long time, it couldn't hold up heavy loads: "You couldn't build a modern skyscraper with Roman concrete," Oleson said. Instead, researchers are trying to take some of the ancient material's specialties and add them into modern mixes.

Is ancient Roman concrete better than today's? Most modern concrete starts with Portland cement, a powder made by heating limestone and clay to super-high temperatures and grinding them up. The ancient builders mixed materials like burnt limestone and volcanic sand with water and gravel, creating chemical reactions to bind everything together. Now, scientists think they’ve found a key reason why some Roman concrete has held up structures for thousands of years: The ancient material has an unusual power to repair itself. Even though Roman concrete lasted a long time, it couldn't hold up heavy loads: “You couldn’t build a modern skyscraper with Roman concrete,” Oleson said.
