SUMMARY
-Granodiorite rocks can easily be carved using temperature techniques. Hundreds of stone spheres were found quarried in the foothills of the Talamanca Mountains. Researchers even saw a gigantic ball weighing over 16 tons.
-The Roman dodecahedron had 12 flat pentagon-shaped faces with a knob protruding on each corner. It might have been a dice, a kid’s toy, a candle holder, a simple decoration, a measuring device on the battlefield, or an astronomical instrument, to name a few.
-The Phaistos Disk was made from clay and measures about 6.2 inches in diameter. Experts concluded that it was a prayer to an ancient Minoan goddess.
-The formula of Greek fire was a well-guarded state secret for over 7 centuries. Greek fire was used in naval warfare.
-Blades made from Damascus steel were the most sought after in medieval Europe. And that’s because they were the best swords at the time.
-The Iron pillar of Delhi dates back to the Gupta period, which lasted from about 240 to 590 C.E. A small amount of rust has started to form, but it is strange that there isn’t more.
-Viking Ulfberht swords are believed to have been made around 800 to 1,000 C.E., but experts were sure that the technology used to make swords of such extraordinary quality didn’t come around until 800 years later.
-The Voynich manuscript has 240 pages broken up into four sections: herbal, astrological, balneological, and pharmacological. There have literally been dozens of failed attempts to crack this thing.
-In 132 C.E., Zhang Heng, a Chinese inventor, astronomer, engineer, scientist, scholar, and artist, invented a seismoscope and presented it to the Han court as an instrument for measuring seasonal winds and the Earth’s movements.
-The Antikythera mechanism was retrieved by a group of divers in 1900 and has been dubbed “the world’s first analog computer” and it was made around 200 B.C.E.

10 Strange Things Found Frozen In Ice Antarctica

10 Strange Things Found Frozen In Ice Antarctica

Antarctica is one of the most mysterious places on Earth. ☃️ It’s the coldest location ever discovered, with an average temperature of -58ºF and an occasional drop to as low as -128.5ºF. ❄️ In addition, this continent remains the least explored. Antarctica has no time zones, no countries, and only 2 ATMs. We're gonna tell you about 10 mysterious and bizarre findings that have been discovered in the ice of Antarctica.

SUMMARY:
- This was a truly shocking discovery: 3 elongated skulls were found in Antarctica in 2014. These skulls were the first human remains uncovered in Antarctica.
- For the last 50 years, people have found more than 10,000 meteorites in Antarctica. Some of them are more than 700,000 years old.
- It turns out that dinosaurs used to live in Antarctica! Since the ‘80s, scientists have discovered almost a ton of fossils there. Most of these remains are more than 71 million years old.
- Archaeologists made another amazing discovery in 2009: the ice of Antarctica had been hiding the fossilized remains of a unique creature. It was the size of a modern cat, but, unlike our popular pets, the animal was egg-laying.
- An unaware onlooker might easily believe that the Taylor Glacier is leaking blood. Terrifying blood-red liquid indeed flows over the ice and falls into the sea. Luckily, the origin of this water isn't dramatic at all. This unusual waterfall contains so much iron oxide that it makes the water look like blood.
- While Antartica is a snow-covered continent, you probably wouldn’t associate it with a lack of water. However, this land is home to one of the driest locations on our planet: the Dry Valleys.
- 2 boxes of excellent Scotch whiskey were hidden in the ice of Antarctica for more than 100 years. After archaeologists discovered this unexpected treasure, they didn't remove it from its ice trap immediately because they were afraid of damaging their finding.
- At a depth of 1,100 ft, American archaeologists made a truly terrifying discovery — they came across an unknown creature that didn't resemble any other living being known to people.
- Scientists know of approximately 400 lakes in Antarctica. Due to incredible pressure, water stays liquid even when its temperature is below the standard freezing point.
- In 1914, the Imperial Trans-Antarctic Expedition began. Its aim was to cross the icy continent from one side to the other. 2 ships participated in the voyage. Tragically, one of them got stuck in the ice and was crushed.

SUMMARY:
- The Taj Mahal in India is one of the most romantic buildings in the world. Shah Jahan started its construction in 1631 to honor the memory of his third wife, whom he loved dearly.
- Besides being a monument to eternal love, the Taj Mahal is also a very mysterious place. It hides numerous sealed rooms where no one is allowed to go.
- The Great Sphinx of Giza is the largest monolith statue in the world. It's 66 ft in height, 62 ft in width, and 240 ft in length. According to scientific estimates, this construction was built about 4,500 years ago!
- With the help of a seismograph, researchers discovered 2 rectangular chambers at a depth of 25 ft. These rooms are situated underground, right under the Sphinx's paws.
- Sree Padmanabhaswamy Temple is a real pearl of the Indian state of Kerala. Underneath the temple, there are 6 vaults named A, B, C, D, E, and F. The doors leading to these chambers are massive and made of iron.
- Many people believe that a fatal curse protects the door leading to this chamber. Hypothetically, this curse can be removed if a saint or sage chants a specific mantra in a proper way.
- In central China, buried deep under a hill and surrounded by poisonous mercury, the First Emperor of China, Qin Shi Huang, has been lying undisturbed for more than 2,000 years.
- Sima Qian, the Han dynasty historian, wrote in his "Records of the Grand Historian" that in Qin Shi Huang's tomb, there were scenic towers and palaces for hundreds of officials.
- Streams and rivers of liquid mercury surrounded Qin Shi Huang's tomb. The biggest 2 represented the Yellow River and the Yangtze, the major rivers of China.

MOST Unbelievable Swords Ever Unearthed

MOST Unbelievable Swords Ever Unearthed

From swords for samurai and kings, to swords that can cut through stone here are the histories of some of the most incredible swords ever unearthed.


8) The Wallace Sword: At a massive 5 feet 4 inches long from razor-sharp blade to hilt , the Wallace sword is an intimidating piece of metalwork. Believed to be wielded by William Wallace himself during the Wars of Scottish Independence, the Wallace Sword is surrounded in mystery and much debate. Allegedly, the sword was sent to John de Menteith, the Governor of Dumbarton Castle, after Wallace’s execution in 1305. From there, the sword’s location is unknown until 1505 when King James IV of Scotland paid for the sword’s hilt, pommel, scabbard, and belt to be replaced. According to legend, the King ordered this due to Wallace’s original components being comprised of the dried skin of English commander Hugh Cressingham after his defeat at the Battle of Stirling Bridge. After this, the sword once again goes missing, with no written mention of it until three centuries later, when a letter was received from the War Office in 1875. The letter states that in 1825, the sword was sent to the Tower of London to be repaired. The sword was then sent to Dr. Samuel Meyrick to be analyzed. Dr. Meyrick concluded that the sword’s components could not have belonged to Wallace, citing them as being made no earlier than the 16th century. A heated debate has developed around the authenticity of the Wallace sword, as many find Dr.Meyrick’s evaluation to be invalid due to him not examining the actual blade of the sword, only the parts that were likely replaced by King James. Recent studies have revealed that there are pieces of a 13th century blade in the sword but during repairs, metals from other time periods have been mixed in, making it incredibly difficult to precisely date the sword and nearly impossible to cite an owner.

7) Tizona: Tizona, and its sister sword, Colada, was wielded by Rodrigo Diaz, better known as El Cid. With a name literally meaning, “firebrand”, this sword struck fear into the hearts of countless men during its time at El Cid’s side. El Cid was an incredibly strong military strategist and warrior, fighting for the Castille. He fought with Tizona against the Moors as a chief general of Alfonso VI’s army. It is alleged that El Cid won Tizona from its previous owner, King Yusef of Valencia. Stories of his military prowess rapidly spread, sparking poems and folktales that have survived even into modern times, several surrounding El Cid being chosen by God and Tizona’s supposed magical powers. Tizona’s powers are believed to be related to the bravery and strength of its wielder, growing most powerful when in the hands of El Cid. It is said that men faced with Tizona in a fight will drop to their knees and beg forgiveness or flee if the sword is owned by the right man. One popular story features El Cid after his death in 1099: in it, El Cid was seated, in full armor, in a church with Tizona at his side. A Jewish man plucked a hair from the deceased El Cid’s beard and the sword struck him down, nearly killing him. After being attended to, the man repents and allows himself to be baptized, the power of the sword converting him. Whether any of these tales hold any truth is up to interpretation but the power of Tizona in the hands of El Cid can historically never be denied.

6) Durendal: Durendal is arguably one of the most interesting swords of all time. Given to legendary paladin Roland by King Charlemagne, Durendal is said to contain a tooth from Saint Peter, a piece of Jesus Christ’s mother, Mary’s clothing, blood from Basil of Caesarea, and hair from Saint Denis all within its gold hilt. The wild claims do not end there, though, as Durendal is said to be the strongest sword of all time, fully capable of slicing large boulders in half with just one swing. It is cited in local lore as the cause of an area in the Pyrenees known as “Roland’s Breech” due to Roland swinging it into the rocks, leaving behind a large gash. The sword is also entirely indestructible by any known human means. The location of Durendal is not currently known, though several fake swords have appeared. Some claim it was stolen away by Henry Curtmantel in 1183 after being placed in the chapel of Mary while others claim it was simply lost or destroyed. The most popular story among locals is that Roland threw the sword into the cliffs of Rocamadour, where it stuck due to the sharpness of the blade, though the tourist offices claim it to be a replica.
