While books are a fixture of today’s libraries, humans long constructed great centers of learning without them. That includes one of the oldest known significant libraries in history: the Library of Ashurbanipal. This library, established in modern-day Mosul, Iraq, by the Assyrian King Ashurbanipal in the seventh century BCE, contained nothing we would recognize today as a book. Instead, it was a repository of 30,000 clay tablets and writing boards covered in cuneiform — the oldest writing system in the world. Much like your local public library, this royal collection covered a variety of subjects, including legislation, financial statements, divination, hymns, medicine, literature, and astronomy. 

Ancient Greeks invented paper.

It's a fib

The ancient Greeks can be thanked for a great many things, but paper isn’t one of them. On March 11, 105 CE, court official Cai Lun presented his papermaking process to Emperor He of the Han dynasty in China. It’d take many centuries, but the idea transformed the world.

While we know when this library flourished, defining the appearance of the earliest book is slightly murkier. The Egyptians, for example, are known to have written on papyrus scrolls; when the Library of Alexandria in Egypt burned in the first century BCE, 40,000 priceless scrolls were lost. By about the second century CE, Romans began using bound codexes, a kind of proto-book that consisted of papyrus or parchment sheets between wooden covers. The arrival of Christianity made the codex immensely popular, and it basically replaced the scroll by the sixth century CE. Block-printed books showed up in China around 700 CE, although Europe didn’t see anything similar until Johannes Gutenberg invented mechanical movable type around 1448. So while libraries haven’t always housed books, they have been repositories of human knowledge — in whatever form it might take.

The Library of Congress has burned twice.

The U.S. Library of Congress contains the largest collection of published books in world history — but it wasn’t an easy journey getting there. During the War of 1812, the British set fire to the Capitol building, which contained the 3,000-volume Library of Congress. It was completely consumed in the conflagration. To reestablish the library, Congress purchased former President Thomas Jefferson’s book collection — the largest in the U.S. at the time — for $23,950. Sadly, a second fire, on Christmas Eve 1851, consumed a large portion of that library, including many of Jefferson’s original volumes. Two years later, Congress constructed a new library, this time made from flame-resistant cast iron.

The Library of Congress has one of the largest collections of books in human history — and that includes comic books. With more than 12,000 titles stretching across 140,000 issues in its collection, the library holds the largest public collection of comic books in the United States. There’s a little bit of everything — Golden Age superheroes like Superman and Captain America, translated reissues of Japanese manga, foreign translations of American comics, underground comics from the ’70s and ’80s, bande dessinées (French comics) from the ’60s, and much more. The library also has many older comics available on microfiche, including the always-elusive Action Comics #1 (the first appearance of Superman), and it regularly adds comics electronically as they become available. 

The Library of Alexandria is one of the Seven Wonders of the Ancient World.

The Egyptian city of Alexandria does make the list, but it’s their famous lighthouse that nabs the accolade — not the library. Both were built around 280 BCE. The lighthouse was a ruin by the 14th century, but its remains were rediscovered in the 20th century.

Of course, this isn’t a collection you can simply peruse at your leisure. Due to the fragility of the comics (the oldest issue is nearly 90 years old, after all), these specimens are only available to “researchers under special conditions” — but that includes people such as scriptwriters, pop culture historians, avid collectors, and graphic artists. The Library of Congress has also put on several public comic-centric exhibitions to showcase some of the most intriguing artifacts in its collection.

The Library of Congress used to have a book-delivering conveyor belt.

In 1897, the Library of Congress moved out of the Capitol building and into new digs across the street. Congressmen grumbled at having to cross the street to get books, so the Army Corps of Engineers created a tunnel between the two buildings, and Boston’s Miles Pneumatic Tube Company designed a “book conveying apparatus.” Requests for books came to the library via pneumatic tube, after which the requested edition was whisked away in a tray that rode the rails at a speed of about 10 feet per second. Once at the Capitol, the book would travel up three stories until it arrived near the House floor. The whole trip took about a quarter-mile, and lasted only five minutes. The library built updated conveying systems in the following years to connect annex buildings constructed in 1939 and 1980, but the original tunnel conveyor system was dismantled in the 2000s to make way for a subterranean visitor center, and the other belts have since been abandoned due to high repair costs. Today, though most senators and representatives just use the internet to get the books they need, a Library of Congress staffer can still sometimes be seen hand-delivering books to the Capitol.

More than 200 years after the 10th President of the United States was born, one of his grandsons is still alive. As impossible as that may seem, the math — and biology — checks out. John Tyler, who was born in 1790 and became President in 1841 after William Henry Harrison died in office (possibly of pneumonia), had a son named Lyon Gardiner Tyler in 1853. This son was born to the then-60-something Tyler and his second, much younger, wife, Julia Gardiner. Lyon then had two sons of his own in his 70s (also with a much younger second wife), one of whom — Harrison Ruffin Tyler, born in 1928 — is still gracing the Earth in his 90s.

George H.W. Bush and George W. Bush were the only father and son to both become President.

Ready to reveal?

Oops, incorrect!

It's a fib

The Bushes were preceded in this exceedingly rare feat by John Adams (1797–1801) and John Quincy Adams (1825–1829), the second and sixth Presidents, respectively.

It may make this feat slightly less surprising to know that Tyler had 15 children, more than any other POTUS in U.S. history. Tyler’s actual presidency is less remarkable than this biographical oddity, alas — he was referred to as “His Accidency” upon assuming office and wasn’t renominated in the following election. (He was also an enslaver whose profitable plantation ran on the labor of 40 to 50 enslaved people.) Though his grandsons haven’t had major political aspirations, you might say it was in Tyler’s blood to seek office: His father, John Tyler Sr., was roommates with Thomas Jefferson at the College of William and Mary and later served as the 15th governor of Virginia.

Theodore and Franklin Roosevelt were fifth cousins.

It’s well known that the two commanders in chief were related, but how they were related is less-common knowledge. FDR assumed the presidency 24 years after his fifth cousin left the Oval Office, and their mutual political aspirations were no coincidence: The longest-serving President in U.S. history greatly admired his distant relative and intentionally followed in his footsteps. Teddy largely approved: Upon Franklin’s engagement to Eleanor — Franklin’s fifth cousin once removed — the younger Roosevelt received a note from the elder saying he was “as fond of Eleanor as if she were my daughter; and I like you, and trust you, and believe in you.”

The Earth has been around for a while — about one-third as long as the universe itself. By comparison, Homo sapiens are the new kids on the block. Earth’s story began at the outset of the Hadean eon, about 4.6 billion years ago. It took 600 million years just for the Earth’s crust to take shape, another 300 million years for the first signs of microbial life to pop up, and about 3.2 billion years after that for life to really get going thanks to the evolutionary burst known as the Cambrian explosion. Several mass extinction events and some 465 million years later, mammals finally took center stage, but modern humans didn’t enter the biological limelight for another 65 million years. With the first Homo sapiens appearing around 300,000 years ago, humans have only been on planet Earth for 0.0067% of its existence. 

Pangea is the only supercontinent in Earth’s history.

Ready to reveal?

Oops, incorrect!

It's a fib

Before Pangea, there was Rodinia (which formed about 1 billion years ago), and geologic evidence suggests that another supercontinent called Nuna formed around 1.6 billion years ago. Scientists believe supercontinents occur in cycles stretched across hundreds of millions of years.

In those 300,000 years, humans have been pretty busy. For a couple thousand years, we harnessed fire and lived a nomadic existence, until around the fourth millennium BCE, when the very first civilizations began to take shape. Since then, humans have been on a meteoric trajectory, going from hunter-gatherer to spacefarer in less than 6,000 years. Carl Sagan famously displayed the universe’s history on a 365-day calendar, with the Big Bang on January 1 and our current moment starting at 12:01 a.m. the next year. On that timeline, it’s only at 10:30 p.m. on December 31 that humans first appear, and all of recorded history is squeezed into just a few seconds — but what a few seconds it’s been.

A growing number of scientists want to declare a new epoch because of humanity’s impact on the Earth.

Geologists divide the life of the Earth into various categories of time. First, there are eons, which stretch for millions and sometimes billions of years. Then come eras, followed by periods, epochs, and finally ages. For the past 11,700 years, since the end of the Paleolithic ice age, the rise of humanity has coincided with the Holocene Epoch (which is part of the Quaternary period of the Cenozoic era). For most of this epoch, the world’s climate remained stable, but with the rise of modern society, the Earth has undergone rapid changes in a very short time. That’s why many scientists believe that a new epoch, called the Anthropocene (meaning “recent age of humans”), should be adopted, beginning around 1950 and the dawn of the nuclear age. For the Anthropocene to become official, both the International Commission on Stratigraphy and then the International Union of Geological Sciences need to sign off. Despite support within these groups, the epoch has yet to be officially recognized.

Juneteenth is a more recent addition to most American calendars, and the first new federal holiday in nearly four decades. So it might come as a surprise that the celebration already has a flag of its own, and one that’s been around for more than 25 years. Designed back in 1997, the flag came about at a time when advocates were rallying for the holiday — which celebrates the end of slavery in the U.S. — to gain federal recognition. In the years since, the design (originally crafted by activist Ben Haith) has undergone minor changes but remains heavy with symbolism. The banner’s solid white star represents freedom and nods to Texas (aka the Lone Star State) for its role in the creation of Juneteenth; on June 19, 1865, enslaved people were officially emancipated in Texas more than two years after President Abraham Lincoln signed the Emancipation Proclamation to abolish slavery in Confederate states. Also featured on the flag is a white sunburst, portraying new beginnings. Both stars sit atop an arching blue and red horizon that signifies optimism for the future. The three-toned flag purposely uses the same colors as the American flag as a reminder that formerly enslaved people and their descendants are Americans, too, despite the country’s history of unequal rights.

The last enslaved people in the U.S. were set free on Juneteenth.

Ready to reveal?

Oops, incorrect!

It's a fib

Juneteenth honors a date when enslaved Americans in Texas were liberated, but it wasn’t the true ending of slavery. Despite Lincoln’s famous decree, some areas (such as Delaware and Kentucky) permitted the practice until the 13th Amendment ending slavery was ratified in December 1865.

Juneteenth’s official flag is raised alongside the Stars and Stripes above government buildings, on college campuses, and in front yards around the country, but it also sometimes appears next to the Pan-African flag at reunions, block parties, and other Juneteenth festivities. Introduced in 1920 by a group led by political activist Marcus Garvey, the three-striped banner of the Pan-African flag is identifiable by its horizontal red, black, and green bands, which represent the blood, people, and growth of the African diaspora. Both flags are meant as inspiring symbols of unity and remembrance — ideas worth celebrating on America’s second Independence Day.

The Emancipation Proclamation is rarely on display.

The United States’ most famous founding documents are relatively easy to see in person. Take the Declaration of Independence and the Constitution, for example, which are on permanent display at the National Archives Museum in Washington, D.C. But despite its historical significance, the original Emancipation Proclamation is seldom showcased. That’s because the handwritten, double-sided document hasn’t aged well (physically). Archivists attribute its deterioration to the paper used back in 1863, which hasn’t withstood time as well as some older documents such as the Constitution, which were penned on animal-skin parchments. In addition, the U.S. Department of State had custody of the original Emancipation Proclamation until transferring it to the National Archives in 1936, by which point it had sustained considerable damage from handling and light exposure. Today, the Emancipation Proclamation is stored in an environmentally controlled vault and viewable on rare occasions; the pages never leave storage all at once, and are always displayed under extremely low light for short periods of time to maximize their life span.

While you might associate the development of modern universities with intellectual movements like the Renaissance or the Enlightenment, the first universities predate those major periods in history — not by years but by centuries. One of the oldest universities in the world is Oxford University, where teaching began back in 1096. That’s much older than Harvard (established in 1636) or Yale (1701), and it’s even older than some well-known Indigenous civilizations in the Americas, including the Incas, who lived in the Andean region of South America from around the 13th century CE to the mid-16th century. (Other groups and empires have occupied the Andes since at least 10,000 BCE.)

The oldest university in the world is in Europe.

The University of al-Qarawiyyin in Fez, Morocco, was built by Fatima al-Fihri, the daughter of a rich merchant, in 859 CE. By the 10th century, it had evolved into the largest Arab university in North Africa. Today, it is the oldest continually operating university in the world.

The first universities were not like the sprawling campuses of today. Instead, they were more like guilds devoted to certain subjects or crafts. Slowly, the influence of these schools grew throughout the High Middle Ages (1000–1300), and many of them became hot spots during future intellectual movements. Meanwhile, as Europe was busy cementing the importance of its universities (and fighting in half-a-dozen Crusades), the Incas were building sprawling road networks and reliable postal systems — they even had highly skilled brain surgeons.

The Incas used string and knots to record information.

Although the Incas had no known written language, they weren’t without a means of recording important information. Quipu were Andean textiles that used a system of colored string and knots to record data. These textiles were both recorded and read by officials known as “quipucamayocs.” Evidence suggests that quipu were first developed by the Wari civilization, who lived in Peru between about 450 and 1000 CE. Scholars believe the Incas used quipu both to record hard data — such as census figures, inventory, and other administrative information — and as a way to encode Incan myths and histories. Because of the Andes’ arid climate, the quipu were well-preserved for centuries. Today, hundreds of quipu are displayed in museums around the world, with the biggest collection now residing at the Ethnological Museum of Berlin in Germany.

In the 1950s, Americans were looking for ways to spend less time in the kitchen. Generations of home cooks, the overwhelming majority of them women, had made food preparation the focus of their day; historians estimate that in 1900, an average household spent 58 hours per week on housework. But a few decades later, postwar innovations such as affordable appliances created more free time — and so did a new wave of commercially prepared and processed foods, an emerging industry fueled by scientists such as William A. Mitchell. While Mitchell’s name isn’t widely known today, his most popular inventions are major name brands, including Cool Whip, Pop Rocks, and Tang.

Tang was developed for NASA astronauts.

Ready to reveal?

The vitamin-infused powder is forever linked with space exploration, but General Foods originally planned Tang as a travel-friendly drink mix for consumers. NASA, looking for easier ways to transport beverages to space, took notice and first stocked it on the 1962 Friendship 7 mission.

Growing up in Minnesota, Mitchell spent his teenage years as a farmhand and carpenter, working to fund his college tuition. It took a few years for the future inventor to venture into food production after graduation, chemistry degree in hand; he worked at Eastman Kodak creating chemical developers for color film, as well as at an agricultural lab. He then went to work at General Foods in 1941, contributing to the war effort by creating a tapioca substitute for soldier rations. (Overseas, GIs renamed the gelatin and starch blend “Mitchell’s Mud.”) The postwar years saw Mitchell churn out a few flops, like carbonated ice, as well as now-iconic hits. In 1956, his quest to create a self-carbonating soda led to the accidental invention of Pop Rocks. A year later, he developed Tang Flavor Crystals, which skyrocketed to popularity after NASA used the powder in space to remedy astronauts’ metallic-tasting water. And by the time he’d retired from General Foods in 1976, Mitchell had developed a quick-set gelatin, powdered egg whites, and a whipped cream alternative — the beloved Cool Whip that now dominates grocery store freezers.

Pop Rocks are known as a totally rad treat of the 1980s, but the candy’s first release in the 1970s was a dud. General Foods initially released the candy in 1975, hoping to capitalize on its innovative appeal. But soon after the confection hit stores, rumors began to spread that it was dangerous, even deadly — supposedly, the carbon dioxide that caused the miniature explosions could mix with carbonated soda and cause children’s stomachs to explode. General Foods and inventor William Mitchell tried to combat the unfounded stories with newspaper ads, a telephone hotline, and by sending letters to 50,000 school principals around the U.S. But amid persistent rumors and slumping sales, General Foods stopped marketing the candy and sold the brand to Kraft in 1985, who marketed it as “Action Candy” — though today’s sweet tooths can once again find the candy under its original name.

Should you ever come across an Academy Award on eBay, there’s a good chance it shouldn’t be there. That’s because Oscar winners aren’t allowed to sell their statuettes without first offering them back to the Academy of Motion Picture Arts and Sciences for the nominal fee of $1, which is meant to maintain their prestige. As the Academy’s official regulations explain, honorees “have no rights whatsoever in the Academy copyright or goodwill in the Oscar statuette or in its trademark and service mark registrations” and “shall not sell or otherwise dispose of the Oscar statuette, nor permit it to be sold or disposed of by operation of law” before first giving the Academy the chance to buy it back. Presumably, the Academy always accepts that $1 offer in order to protect the brand, though it’s not clear how often, if ever, it’s actually happened. 

A sequel has never won Best Picture.

Both “The Godfather Part II” (1974) and “The Lord of the Rings: The Return of the King” (2003) won Best Picture. Just as impressive, all three films in both trilogies were nominated for Best Picture — and the original “Godfather” won it as well.

The rule is strictly enforced, with winners having to sign a contract before taking possession of their statuette. It also applies to their family members and descendants. Not everyone has abided by it, however. To take just one example: The trophy awarded to art director Joseph C. Wright, who won for his work on 1942’s My Gal Sal, was sold to an auction house for $79,200 in 2015. This led to the Academy winning a lawsuit enforcing the rule — and likely discouraging any future honorees from trying to break it.

Today Leonardo da Vinci’s “Mona Lisa” is probably the most famous painting in the world — and it deserves the accolade. Painted between 1503 and 1519, this portrait (commonly believed to be of Italian noblewoman Lisa del Giocondo) reflects the Renaissance polymath’s deep understanding of his art form and has been analyzed in depth for decades, if not more. Although certain sectors of the art world regarded the portrait as a masterwork by the 1860s, the general public knew little about it until the 20th century. Then, the unthinkable happened — the “Mona Lisa” was stolen.

The “Mona Lisa” once hung in Napoleon Bonaparte’s bedroom.

Ready to reveal?

Oops, incorrect!

It's a fact

First displayed by a Leonardo da Vinci patron, French King Francois I, the “Mona Lisa” was a mainstay of royal residences but rode out the French Revolution (at the end of the 18th century) in a warehouse. Later, it hung in Napoleon’s bedroom in Paris’ Tuileries Palace for four years.

In the early morning hours of August 21, 1911, after spending the night hiding in an art-supply closet in the Louvre, three Italian “handymen” snuck over to the “Mona Lisa,” unhooked it from its protected location, tossed a blanket over their pilfered prize, and snuck away undetected, boarding a train at the Quai d’Orsay station at 7:47 a.m. The theft became an international scandal, and newspapers around the world ran stories about the more than two-year-long search for the missing masterpiece. Finally, in December 1913, the painting was found in Florence, Italy, after an attempted sale by the heist’s ringleader, Vincenzo Perugia — who had actually worked at the Louvre for a time, installing glass cases over the paintings. The treasure then went on a tour of Italy until it returned to the famous French museum in early 1914. Although the “Mona Lisa” and her mischievous smile survived unharmed, the painting’s reputation had changed forever, with the many headlines about the theft making her a household name that has endured to this day.

Edvard Munch’s “The Scream” was also stolen… twice.

No painting captures existential dread quite like Edvard Munch’s “The Scream.” Created in 1893, Munch’s masterpiece depicts a ghostly figure, not mid-scream as many assume, but instead hearing “the great scream throughout nature,” according to the artist’s own inscription on a lithograph edition of the work. The painting is so famous, it’s one of the few works of art to receive the rare honor of its own emoji. Of course, popularity can also inspire the wrong kind of attention, and in February 1994, on the opening day of the Winter Olympics in nearby Lillehammer, Norway, two thieves stole Munch’s masterwork from Oslo’s National Gallery. The burglars left behind only a brief note: “Thousand thanks for the poor security.” Fortunately, the painting was recovered — identified as genuine thanks to a splash of candle wax on its front — three months later in Åsgårdstrand, Norway, a town where Munch lived and worked for years. Then, in 2004, another version of “The Scream” (Munch painted several) was stolen from the Munch Museum in Oslo; it was recovered two years later. As happened with the “Mona Lisa,” these thefts — though terrible crimes — only added to the painting’s international renown.

Founded in 1800, the library predates every other federal cultural institution in the U.S. — it's so old, in fact, that it was brought into existence by the same bill that relocated the capital to Washington, D.C., from Philadelphia.

The library doesn't just house printed materials, of course. It contains everything from the contents of Abraham Lincoln’s pockets on the night he was assassinated to hundreds of billions of tweets and Amelia Earhart’s palm print. The British Library and its massive catalogue is next on the list of the world’s largest libraries, with the top five rounded out by the New York Public Library, Library and Archives Canada, and the Russian State Library.

The original library was burned down in the War of 1812.

The Library of Congress was comparatively tiny for the first 14 years of its existence, but that didn’t make it any less tragic when its collection of 3,000 books was destroyed along with the Capitol building on August 24, 1814. The conflagration that took it down, part of the War of 1812, necessitated a new location. Enter Thomas Jefferson, who offered his own collection of 6,487 books (then the largest personal library in the nation) as a replacement for the lost volumes. Though he didn’t do so for free — Congress paid him $23,950 — Jefferson did provide the foundation for what the library would eventually become. Sadly, a second fire destroyed most of his contribution as well as nearly two-thirds of the entire collection on Christmas Eve 1851, but the institution rose from the ashes once again.
