(Way More Than) Everything You Wanted To Know About Guinea Pigs

Let's get this straight. They're not pigs. They're rodents. And they're not from Guinea, either, so the name is just downright misleading. Cavies (cavia porcellus), also known as guinea pigs, are tame, become accustomed to handling, and rarely bite, making them not only ideal pets but ideal lab animals. And in some cases, a crunchy snack or homeopathic diagnostic tool—especially when the pig is drunk. Here's some delicious peeg trivia the next time you need to impress the boss or in-laws.

They Used to be HUMONGOUS

Eight million years ago, the ancestor of the guinea pig was the buffalo-sized 1,545-pound rodent Phoberomys pattersoni. It lived a semi-aquatic life in the ancient Orinoco delta in northern Venezuela, frolicking amongst lion-sized marsupial cats and three meter long crocodiles.

High-Profile Owners

Queen Elizabeth I is purported to have owned a guinea pig, starting the trend of keeping guinea pigs as a pet. Theodore Roosevelt's family raised guinea pigs. In letters, he complained about being forced to babysit them.


Guinea pigs are crepuscular—mostly active during twilight hours. This is due to their domestication; subdued indoor lighting has led them to prefer neither direct sunlight nor total darkness.

Once only consumed by ancient royalty and elite or reserved for ceremonial meals, a dish of guinea pig, or Cuy, has gradually become common in Peruvian, Ecuadorian, and Bolivian diet. The guinea pig, native to South America, has meat that is high in protein and low in fat and cholesterol, similar to rabbit or the dark meat on chicken.

There isn't much space to raise cattle in the mountains, so modern day Andean Indians and Peruvians often raise guinea pigs as a food or income source. They will keep eight to fifteen guinea pigs at a time for food, although some families may have as many as forty or fifty running amok in their home. With the exception of the occasional egg, guinea pig meat is often the only source of animal protein available to Andean Indians.

During World War II, the government encouraged Italian peasants to raise guinea pigs to supplement their meat rations, but this campaign did not go over very well.

A recipe for cooking guinea pig can be found here, but be warned that you may need to buy and cook three or four at a time in order to feel full. Also, be warned: guinea pig meat is illegal in several places, including California.

Avast, That Peeg Thar has Scurvy

Like humans, guinea pigs are one of the few mammals that cannot make or store their own Vitamin C (ascorbic acid). Because guinea pigs do not have L-gulonolactone oxidase (GULO), an enzyme that produces Vitamin C, guinea pigs have to get all of their vitamin C from food or "“ again,like humans "“ they will die from scurvy. The only other known animals that cannot synthesize their own Vitamin C are primates, fruit eating bats, and a specific species of bird and trout, respectively.

When scientists study the effect of Vitamin C on humans, they almost always use guinea pigs as the test animal. Vitamin C overdose has been correlated to osteoarthritis, and guinea pigs develop knee arthritis in a manner similar to humans.

Male guinea pigs can mate with as many as forty guinea pigs, although the common ration is one male to seven females. In 2000, BBC reported on Sooty, a Welsh guinea pig who knocked up 24 females over the course of 2 days and fathered 42 babies. [Photo credit.]

Cavies as Ceremonial Mediums and X-ray Machines

The guinea pig was regarded as an important divination tool. Incan haruspices would open the animals with their fingernails and inspect the entrails to prognosticate. Even to this day, guinea pigs are sometimes used in rural areas as sacrificial offerings or for fortune telling.

In addition, curanderos, South American folk healers, use guinea pigs as a diagnostic and healing tool. A live guinea pig is rubbed over the body of the sick patient, and the pig's reaction is used to gauge the illness. If the pig dies during this rubbing procedure, it is generally considered a bad sign. Afterwards, some curanderos will split open the guinea pig to examine its internal organs and arrive at a diagnosis, or kill the guinea pig in order to destroy the disease. Modern day takes on this practice include feeding the guinea pig beer (making the guinea pig's healing powers more potent) and adorning it with ribbons before giving the patient a rub down. The guinea pig is then set free, taking the disease with it.

High Maintenance Nakedness

Originally bred for dermatological laboratory research and chemical testing, these hypoallergenic guinea pigs have a weaker immune system and resemble baby hippos. They are very easily sunburned, sensitive to the cold, and their delicate rumps require frequent moisturizing with lotion. [Photo credit.]

9 Curses for Book Thieves From the Middle Ages and Beyond

It may seem extreme to threaten the gallows for the theft of a book, but that's just one example in the long, respected tradition of book curses. Before the invention of moveable type in the West, the cost of a single book could be tremendous. As medievalist Eric Kwakkel explains, stealing a book then was more like stealing someone’s car today. Now, we have car alarms; then, they had chains, chests … and curses. And since the heyday of the book curse occurred during the Middle Ages in Europe, it was often spiced with Dante-quality torments of hell.

The earliest such curses go back to the 7th century BCE. They appear in Latin, vernacular European languages, Arabic, Greek, and more. And they continued, in some cases, into the era of print, gradually fading as books became less expensive. Here are nine that capture the flavor of this bizarre custom.

The Arnstein Bible at the British Library, written in Germany circa 1172, has a particularly vivid torture in mind for the book thief: “If anyone steals it: may he die, may he be roasted in a frying pan, may the falling sickness [i.e. epilepsy] and fever attack him, and may he be rotated [on the breaking wheel] and hanged. Amen.”


A 15th-century French curse featured by Marc Drogin in his book Anathema! Medieval Scribes and the History of Book Curses has a familiar "House That Jack Built"-type structure:

“Whoever steals this book
Will hang on a gallows in Paris,
And, if he isn’t hung, he’ll drown,
And, if he doesn’t drown, he’ll roast,
And, if he doesn’t roast, a worse end will befall him.”

In The Medieval Book, Barbara A. Shailor records a curse from Northeastern France found in the 12th-century Historia scholastica: “Peter, of all the monks the least significant, gave this book to the most blessed martyr, Saint Quentin. If anyone should steal it, let him know that on the Day of Judgment the most sainted martyr himself will be the accuser against him before the face of our Lord Jesus Christ.”


Drogin also records this 13th-century curse from a manuscript at the Vatican Library, as notes. It escalates rapidly.

"The finished book before you lies;
This humble scribe don’t criticize.
Whoever takes away this book
May he never on Christ look.
Whoever to steal this volume durst
May he be killed as one accursed.
Whoever to steal this volume tries
Out with his eyes, out with his eyes!"

An 11th-century book curse from a church in Italy, spotted by Kwakkel, offers potential thieves the chance to make good: “Whoever takes this book or steals it or in some evil way removes it from the Church of St Caecilia, may he be damned and cursed forever, unless he returns it or atones for his act.”


This book curse was written in a combination of Latin and German, as Drogin records:

"To steal this book, if you should try,
It’s by the throat you’ll hang high.
And ravens then will gather ’bout
To find your eyes and pull them out.
And when you’re screaming 'oh, oh, oh!'
Remember, you deserved this woe."


This 18th-century curse from a manuscript found in Saint Mark’s Monastery, Jerusalem, is written in Arabic: “Property of the monastery of the Syrians in honorable Jerusalem. Anyone who steals or removes [it] from its place of donation will be cursed from the mouth of God! God (may he be exalted) will be angry with him! Amen.”

A 17th-century manuscript cookbook now at the New York Academy of Medicine contains this inscription: "Jean Gembel her book I wish she may be drouned yt steals it from her."


An ownership inscription on a 1632 book printed in London, via the Rochester Institute of Technology, contains a familiar motif:

“Steal not this Book my honest friend
For fear the gallows be yr end
For when you die the Lord will say
Where is the book you stole away.”


One of the most elaborate book curses found on the internet runs as follows: "For him that stealeth a Book from this Library, let it change to a Serpent in his hand and rend him. Let him be struck with Palsy, and all his Members blasted. Let him languish in Pain, crying aloud for Mercy and let there be no surcease to his Agony till he sink to Dissolution. Let Book-worms gnaw his Entrails in token of the Worm that dieth not, and when at last he goeth to his final Punishment let the Flames of Hell consume him for ever and aye.”

Alas, this curse—still often bandied about as real—was in fact part of a 1909 hoax by the librarian and mystery writer Edmund Pearson, who published it in his "rediscovered" Old Librarian's Almanack. The Almanack was supposed to be the creation of a notably curmudgeonly 18th-century librarian; in fact, it was a product of Pearson's fevered imagination.

John W. Jones: The Runaway Slave Who Buried Nearly 3000 Confederate Soldiers

John W. Jones was as close to a sinless man as you could find—with the exception of the time he lied to his mother.

It was a late June evening in 1844 and the 26-year-old enslaved man, who lived on a plantation near Leesburg, Virginia, told his mother that he was leaving to attend a party. His real plans were much riskier. Jones slipped outside, grabbed a pistol, and rendezvoused with four other enslaved men. With starlight as their guide, they crept through the Virginia woods. Their destination: North.

The men hiked approximately 20 miles every day, dodging slave catchers in Maryland and crossing the Mason-Dixon Line into the free state of Pennsylvania. Following a major route along the Underground Railroad, they needled through Harrisburg and Williamsport and traced a path along what is now State Route 14. When the exhausted men snuck into a barn near the New York border to sleep, Jones kept guard as the others rested: He sat down, laid a shotgun on his lap, and kept his eyes peeled.

“He was serious about getting his freedom,” says Talima Aaron, President of the John W. Jones Museum Board of Trustees. “He understood the danger, and he constantly took responsibility for others. You’ll notice that was a thread for him—responsibility for others.”

Jones never had to use the gun. When the barn’s owner, Nathaniel Smith, discovered the five men on his property, he invited them into his home. His wife Sarah served the group hot biscuits and butter and cared for them until their strength returned. It was the first time many of them had ever been inside a white person’s home. According to an 1885 profile in The Elmira Telegram, the gesture brought the men to tears.

On July 5, 1844, Jones crossed a toll bridge into Elmira, New York, with less than $2 in his pocket. Unlike most runaways bound for Canada, Jones decided to stay in Elmira. It’s here that Jones would become one of the country's most successful Underground Railroad conductors, one of the richest black men in the state of New York, and the last earthly link for nearly 3000 dead Confederate soldiers.


Living in the north did not mean Jones had it easy. He could not vote. He still shared sidewalks with former slave-owners. When he asked to receive an education at the local schools, he was denied.

But Jones had a knack for cracking ceilings. After earning the admiration of a local judge, he was allowed to study at an all-women’s seminary, exchanging janitorial work for reading and writing lessons. He joined a church with abolitionist leanings and become its sexton, maintaining its cemetery. Then he became the sexton of a second cemetery, and then a third. The community quickly grew to respect his work ethic and, eventually, Jones had earned enough money to buy a small house—a house that he transformed into a vital hub for the Underground Railroad.

At the time, the Underground Railroad—an informal network of trails, hiding places, and guides that helped slaves escape northward—was under intense scrutiny. The 1850 Fugitive Slave Act had created financial incentives to report runaways living in free states. “Slave catchers from the south could come up to a place like Elmira and claim that a person of color was a runaway slave, and they could haul them back into slavery—even if that person had been born free,” says Bruce Whitmarsh, Director of the Chemung County Historical Society. There were steep penalties for aiding a person’s escape.

Jones didn’t care. Not only did he join the Underground Railroad, he was openly vocal about it, loudly pledging his opposition to the Fugitive Slave Act in a message that was published in abolitionist newspapers across the region: “Resolved, that we, the colored citizens of Elmira, do hereby form ourselves into a society for the purpose of protecting ourselves against those persons, (slave-catchers) prowling through different parts of this and other States.” Jones committed to resisting the law, even at the risk that “everyone of us be assassinated.”

The Underground Railroad in Elmira was unique: Since the town included the only train stop between Philadelphia and Ontario, it actually involved locomotives. Jones communicated regularly with William Still, the chief "conductor" of the Underground Railroad in Philadelphia, and built a cozy network of abolitionists who worked on trains passing through town. He provided runaways with housing, food, and even part-time jobs. “Runaways usually came in groups of four, six, or 10,” Aaron says. “But he had up to 30 at once in his little house.” Jones arranged hiding space for all of the escapees on the 4 a.m. “Freedom Baggage Car” to Canada, as it was unofficially known.

Over the course of nine years, Jones aided the escape of around 800 runaway slaves. Not one was captured.

During the last years of the Civil War, the same railroad tracks that had delivered hundreds of runaways to freedom began to carry thousands of captive Confederate soldiers to Elmira’s new prisoner of war camp. Once again, Jones would be there.


Of the 620,000 Civil War deaths, approximately 10 percent occurred at prison camps. The most notorious P.O.W. camp—in Andersonville, Georgia—saw 13,000 Union troops, or approximately 29 percent of the prison population, perish. After the war, Andersonville's commander was tried for war crimes. The camp is now a National Historic Site.

Meanwhile, the prison camp in Elmira has been largely forgotten. Today, the riverside site is little more than an unremarkable patch of dandelion-speckled grass; a small, easy-to-miss monument is the only marker. It belies the fact that while Elmira's camp was noticeably smaller than Andersonville's—only one-quarter its size—it was just as deadly: If you were a prisoner at “Hellmira,” there was a one-in-four chance you would die.

Elmira was never supposed to have a prison camp; it was a training depot for Union soldiers. But when the Confederacy began refusing to exchange African-American soldiers—who it considered captive slaves, not prisoners of war—the Union stopped participating in prisoner exchanges. “Both sides started scrambling for places to expand, and that’s how Elmira got caught up in the web,” says Terri Olszowy, a Board Member for the Friends of the Elmira Civil War Prison Camp.

The rollout was ill-planned, Olszowy explains. When it opened in July 1864, the camp had no hospital or medical staff. The first prisoners were already in rough shape and deteriorated quickly. Latrines were placed uphill from a small body of water called Foster’s Pond, which quickly became a cesspool. A shelter shortage meant that hundreds of soldiers were still living in tents by Christmas. During spring, the Chemung River flooded the grounds. Rats crawled everywhere. When authorities released a dog to catch them, the prisoners ate the dog.

The camp grew overcrowded. Designed to hold only 5000 prisoners, it saw approximately 7000 to 10,000 men confined there at its peak. Across the street, an observation tower allowed locals the opportunity to gawk at these prisoners through a pair of binoculars. It cost 10 cents.

It must have been a depressing sight, a scene of men stricken with dysentery, scurvy, typhoid, pneumonia, and smallpox. Many prisoners attempted to escape. One group successfully dug a 66-foot tunnel with spoons and knives. One man fled by hiding in a barrel of swill. Another hid inside a coffin, leaping out as he was being hauled to Woodlawn Cemetery.

It’s said that 2973 Confederate prisoners left the Elmira prison camp in coffins for real. The job to bury them belonged to the town’s sexton: John W. Jones.


The P.O.W. cemetery in Elmira is unique. The dead at many prison camps were buried in mass graves; Chicago’s Oak Woods Cemetery, for example, contains a plot filled with the remains of prisoners detained at Camp Douglas that is believed to be largest mass grave in the western hemisphere. All 2973 of the dead at Elmira, however, received an individual, marked grave in a special section of Woodlawn cemetery. Only seven are unknown. Jones's effort to give each soldier an individual grave, as well as his meticulous record-keeping, were a big part of why the federal government designated the P.O.W. portion of Woodlawn a "National Cemetery" in 1877—a status awarded to veterans' cemeteries deemed to be of national importance, and which has only been awarded to 135 cemeteries nationwide.

Jones treated each dead soldier with superhuman levels of grace. Overseeing a crew of 12, he managed the burial of about six soldiers every day, treating each body as if that person had been a member of his own church. He kept detailed records of each soldier’s identity by creating improvised dog tags: Around each person's neck or under their arm, Jones tucked a jar containing a paper detailing their name, rank, and regiment. That same information was neatly scrawled on each coffin. When the dirt settled, Jones marked each plot with a wooden headstone.

“No one told him how to do that job, he did it in the way that he thought was right—even though the people he buried were fighting a war to keep people like him enslaved,” Aaron says. “He even knew one of the young men who had died, and he reached back to the South and told the parents so they knew where their child was buried. That speaks to his compassion.”

According to Clayton W. Holmes’s 1912 book Elmira Prison Camp, “History does not record anything to challenge the assertion that at no prison, North or South, were the dead so reverently cared for, or a more perfect record kept.” In fact, when representatives of the Daughters of the Confederacy came to Elmira at the turn of the century to consider repatriating the remains, Jones’s handiwork convinced them to touch not a blade of grass. Instead, a monument in the cemetery commemorates the “honorable way in which they were laid to rest by a caring man.”

Aaron sees a second moral in the story. “People always talk about the tension between him being an escaped slave and burying with respect and dignity these Confederate soldiers fighting to keep people like him as slaves,” she says. “But to me there’s a subtext: Here is a grown man who escaped slavery, and the first thing he wanted to do when he reached freedom was get an education. Because of that, he was able to keep these meticulous records that later led to this national designation: It became a historical moment because this man, who was denied an education, got one.”

It also made a mark on Jones’s bank account. Jones earned $2.50 for each soldier he buried. It wasn’t much, but by the time he had finished burying nearly 3000 Confederate dead, he had become one of the 10 richest African-Americans in the state of New York. With that money, he bought a handsome farm of at least 12 acres.

It was a bittersweet purchase. Not only is it believed that parts of his home were built from wooden scraps of the disassembled Elmira prison camp, Jones had purchased the home when New York state law stipulated that black men must own $250 worth of property in order to vote. His home—today listed on the National Register of Historic Places [PDF]—earned Jones that right to vote.

For the remainder of his life, Jones continued working as a sexton and church usher. In 1900, he died and was buried in one of the cemeteries that had become his life’s work.

Incidentally, his death also marked the end of a local mystery: For nearly two decades, fresh flowers kept appearing on the freshly manicured grave of a woman named Sarah Smith. Nobody knew why the flowers appeared there or where they originated—until the decorations stopped appearing immediately after Jones’s death. Residents later realized that the grave belonged to the same Sarah Smith who, 56 years earlier, had invited John W. Jones and his friends into her home for butter, biscuits, and a good night’s rest.
