8 Ancient Writing Systems That Haven't Been Deciphered Yet

The Indus Valley civilization was one of the most advanced in the world for more than 500 years, with more than a thousand settlements sprawling across 250,000 square miles of what is now Pakistan and northwest India from 2600 BCE to 1900 BCE. It had several large, well-planned cities like Mohenjo-daro, common iconography—and a script no one has been able to understand. 

Over at Nature, Andrew Robinson looks at the reasons why the Indus Valley script has been so difficult to crack, and details some recent attempts to decipher it. Since we don't know anything about the underlying language and there's no multilingual Rosetta stone, scholars have analyzed its structure for clues and compared it to other scripts. Most Indologists think it's "logo-syllabic" script like Sumerian cuneiform or Mayan glyphs. But they disagree about whether it was a spoken language or a full writing system; some believe it represented only part of an Indus language, Robinson writes. 

One team has created the first publicly available, electronic corpus of Indus texts. Another, led by computer scientist Rajesh Rao, analyzed the randomness in the script's sequences. Their results indicated it's most similar to Sumerian cuneiform, which suggests it may represent a language. Read the full article for more details.   

The Indus Valley script is far from the only one to remain mysterious. Here are eight others you might try your hand at deciphering.

1. Linear A

In 1893, British archaeologist Sir Arthur Evans purchased some ancient stones with mysterious inscriptions on them at a flea market in Athens. On a later trip to the excavations at Knossos on the island of Crete, he recognized one of the symbols from his stones and began a study of the engraved tablets being uncovered at various sites on the island. He discovered two different systems, which he called Linear A and Linear B. While Linear B was deciphered in the early 1950s (it turned out to represent an early form of Greek), Linear A, above, has still not been deciphered.

2. Cretan Hieroglyphics

The excavations on Crete also revealed a third type of writing system, with symbols that looked more picture-like than those of the linear scripts. Some of these symbols are similar to elements in Linear A. It is assumed that the hieroglyphic script developed into Linear A, though the two systems were both in use during the same time period.

3. Wadi el-Hol script

In the 1990s, a pair of Yale archaeologists discovered a graffiti-covered cliff wall at the Wadi el-Hol (Gulch of Terror) in Egypt. Most of the inscriptions were in systems they could recognize, but one of them was unfamiliar. It looks like an early transition from a hieroglyphic to an alphabetic system, but it hasn't yet been deciphered.

4. Sitovo inscription

In 1928 a group of woodcutters found some markings carved into a Bulgarian cliffside. They thought the marks indicated hidden treasure, but none was found. Word got around and soon some archaeologists had a look. Later, the head of the expedition was executed for being a secret agent for the Soviets in Bulgaria. One piece of evidence used against him was a strange coded message he had sent to Kiev—actually a copy of the cliffside inscription he had sent to colleagues for scholarly input. It is not clear what language the inscription represents. Thracian, Celtic, Sarmato-Alanian, and Slavic are some of the possibilities scholars have argued for. Another suggestion is that it's simply a natural rock formation.

5. Olmec writing

The Olmecs were an ancient Mexican civilization best known for the statues they left behind: the so-called "colossal heads." In 1999, their writing system was revealed when road builders unearthed an inscribed stone tablet. The tablet shows 62 symbols; some look like corn or bugs, and some are more abstract. It has been dated to 900 B.C., which would make it the oldest example of writing in the Western Hemisphere.

6. Singapore stone

There once was a giant engraved slab made of sandstone at the mouth of the Singapore River. It had been there for 700 years or so when, in 1819, workers uncovered it while clearing away jungle trees. A few scholars got a look at it before it was blown to bits in order to make space for a fort to protect the British settlements. The parts that didn’t end up in the river were eventually used for road gravel, though some fragments were saved. The script hasn't been deciphered, but there have been various suggestions for what language it might represent: ancient Ceylonese, Tamil, Kawi, Old Javanese, and Sanskrit.

7. Rongorongo

When missionaries got to Easter Island in the 1860s, they found wooden tablets carved with symbols. They asked the Rapanui natives what the inscriptions meant, and were told that nobody knew anymore, since the Peruvians had killed off all the wise men. The Rapanui used the tablets as firewood or fishing reels, and by the end of the century they were nearly all gone. Rongorongo is written in alternating directions; you read a line from left to right, then turn the tablet 180 degrees and read the next line.

8. Proto-Elamite

This ancient writing system was used more than 5000 years ago in what is now Iran. Written from right to left, the script is unlike any other ancient scripts; while the proto-Elamites appear to have borrowed the idea for a written language from their Mesopotamian contemporaries, they apparently invented their own symbols—and didn't bother to keep track of them in an organized way, proto-Elamite expert and Oxford University scholar Jacob Dahl told the BBC in 2012. Around that time, he and his Oxford colleagues asked for help from the public in deciphering proto-Elamite. They released high-quality images of clay tablets covered in Proto-Elamite, hoping that crowdsourcing could decode them. Now a collaboration involving several institutions, the project is ongoing

From Farts to Floozy: These Are the Funniest Words in English, According to Science


Fart. Booty. Tinkle. Weiner. We know these words have the ability to make otherwise mature individuals laugh, but how? And why? Is it their connotations to puerile activities? Is it the sound they make? And if an underlying structure can be found to explain why people find them humorous, can we then objectively determine a word funnier than bunghole?

Chris Westbury, a professor of psychology at the University of Alberta, believes we can. With co-author Geoff Hollis, Westbury recently published a paper ("Wriggly, Squiffy, Lummox, and Boobs: What Makes Some Words Funny?") online in the Journal of Experimental Psychology: General. The two analyzed an existing list of 4997 funny words compiled by the University of Warwick and assessed by 800 survey participants, whittling down the collection to the 200 words the people found funniest. Westbury wanted to see how a word's phonology (sound), spelling, and meaning influenced whether people found it amusing, as well as the effectiveness of incongruity theory—the idea that the more a word subverts expectations, the funnier it gets.

In an email to Mental Floss, Westbury said that a good example of incongruity theory is this video of an orangutan being duped by a magic trick. While he's not responding to a word, clearly he's tickled by the subversion of his own expectations:

With incongruity theory in mind, Westbury was able to generate various equations that attempted to predict whether a person would find a single word amusing. He separated the words into categories—insults, sexual references, party terms, animals, names for body parts, and profanity. Among those examined: gobble, boogie, chum, oink, burp, and turd.

Upchuck topped one chart, followed by bubby and boff, the latter a slang expression for sexual intercourse. Another equation found that slobbering, puking, and fuzz were reliable sources of amusement. Words with the letters j, k, and y also scored highly, and the vowel sound /u/ appeared in 20 percent of words the University of Warwick study deemed funny, like pubes, nude, and boobs.

In the future, Westbury hopes to examine word pairs for their ability to amuse. The smart money is on fart potato to break the top five.

15 Fun Phrases Popularized During Prohibition

Prohibition ended 85 years ago—on December 5, 1933—but the colorful colloquialisms it brought about will live on forever. Here are just a handful of them.

1. Blind pig

An illegal drinking establishment, a.k.a. a speakeasy, that attempted to evade police detection by charging patrons a fee to gaze upon some sort of exotic creature (i.e. a blind pig) and be given a complimentary cocktail upon entrance. Also known as a blind tiger.

2. Juice joint

Yet another term for an illegal drinking establishment.

3. Jake walk

A paralysis or loss of muscle control in the hands and feet, due to an overconsumption of Jamaican ginger, a.k.a. Jake, a legal substance with an alcoholic base. The numbness led sufferers to walk with a distinct gait that was also known as Jake leg or Jake foot.

4. Ombibulous

A term made up by writer H.L. Mencken to describe his love of alcohol; he noted, “I'm ombibulous. I drink every known alcoholic drink and enjoy them all.” Mencken was also fond of referring to bootleggers as booticians and is alleged to have invented the term boozehound.

5. Skid road

A precursor to the term “Skid Row,” a skid road was the place where loggers hauled their goods. During Prohibition, these “roads” became popular meeting places for bootleggers.

6. Brick of wine

Oenophiles looking to get their vino fix could do so by simply adding water to a dehydrated block of juice, which would become wine. (And you thought a box of wine was bad!)

7. Bathtub gin

A homemade—and often poorly made—gin that was preferably served in a bottle so tall that it could not be mixed with water from a sink tap, so was mixed in a bathtub instead. Though the phrase references gin specifically, it came to be used as a general term for any type of cheap homemade booze.

8. White lightning

The whiskey equivalent of bathtub gin; a highly potent, illegally made, and poor-quality spirit.

9. Teetotaler

A person who abstains from the consumption of alcohol. The phrase is believe to have originated within the Prohibition era’s temperance societies, where members would add a “T” to their signatures to indicate total abstinence (T+total-ers). 

10. Dry

A noun used in reference to a man or woman who is opposed to the legal sale of alcoholic beverages. Bureau of Prohibition agents were often referred to as Dry Agents (though corruption among this crew ran rampant). As an adjective, it describes a place where alcohol is not served. 

11. Wet

The opposite of dry, a wet is a person who is for the legal sale of alcoholic beverages or a place where liquor is in full supply.

12. Whale

A heavy drinker. 

13. Blotto

Extremely drunk, often to the point of unconsciousness.

14. Hooch

Low-quality liquor, usually whiskey. The term originated in the late 1800s as a shortened version of “Hoochinoo,” a distilled beverage from Alaska that became popular during the Klondike gold rush. The phrase came back into heavy use in the 1920s. 

15. Giggle water

An alcoholic beverage.
