Double, Double, Toil and Trouble

The witches’ ingredients for the cauldron in Macbeth are mostly coded names for medicinal plants.

Macbeth’s Act 4 opening scene is probably one of the most well known scenes in Shakespeare. The Three Witches (aka the Weird Sisters) are in a dark cave with a boiling cauldron at the center. The witches gather and begin an incantation of dark magic, adding ingredients as they go. “Double, double, toil and trouble; Fire burn, and cauldron bubble.” Each witch then lists a series of ingredients that, at face-value, sound disgusting and macabre. But the ingredients are not what they seem.

Witches, like early alchemists, kept their knowledge a closely guarded secret. After putting all of that effort into R&D you didn’t want the competition getting a hold of your findings. But witches had other reasons for secrecy. Unlike the fictional witches in Macbeth, most “witches” were in reality female medical workers using herbs & botanicals to create medicines. In Medieval Europe medicine was a male-dominated profession and women caught practicing medicine were sometimes branded as witches. As such they had to keep their activity, and their recipes, secret. By using alternate names for their ingredients, the contents of one’s “spell book” were kept secret. Also, using alternate names worked as a safe-guard to keep their proprietary medical knowledge out of the hands of the general public who might mistakenly try to prepare these treatments themselves.

Some believe that almost all of the 23 ingredients in the witches’ brew are actually coded plant names, even the problematically named “liver of blaspheming Jew”. How much of this Shakespeare knew is unclear. All the ingredients together would make an unrealistic ridiculous concoction, so they were probably chosen for theatrical shock value. He may have found a list of real “witches” ingredients and used them without knowing they were coded names. Still, if you want improved blood circulation some eye of newt (aka mustard seed) might help.

Germanic Gods (and Saturn)

In the English language the days of the week are named for six Germanic gods … and the Roman god Saturn.

In the Indo-European family tree of languages, English is a descendant of Germanic languages. English also inherited elements of ancient Germanic culture such as Germanic mythology. The Germanic peoples took the Roman idea of naming the days of the week for various gods, but they changed the Roman gods to Germanic gods (except one).

• Sunday is named after the Germanic goddess Sunna (aka Sól in Norse mythology). Along with her brother Máni, she was taken from their father Mundilfari and placed in the sky. Sunna is the sun, moving across the sky in her chariot. Her brother is the moon, moving across the sky in his chariot. To make sure they keep moving the gods set two wolves to chase each sibling continuously. The wolf Sköll chases Sunna. From her we get the Sun’s day, or Sunday.

Monday is named for the Germanic god Máni, brother of Sunna (as mentioned above). He rides through the sky on his chariot and is chased by the wolf Hati. From him we get Moon’s day, or Monday.

Tuesday is named for the one-armed Germanic god of war Týr (aka Tíw), which became Tīwes day or Tuesday.

• Wednesday is named for Odin (aka Wōden), the central god of the Germanic pantheon of gods. From him we got Wōdnes day which became Wednesday.

Thursday has perhaps the most well-known origin. Pop culture has made the hammer-wielding god of thunder & lightning Thor (aka Þunor – pronounced “Thunor”) one of the most well known Germanic gods. His name is also the origin for our word thunder which, in modern German, is “donner” and gives us Donnerstag or “Thunder day / Thursday.” In English Thor’s day became Thursday.

Friday is named for the Germanic goddess Frigg (aka Frīja, or Frea). She was the wife of Odin and, given a good deal of mythological overlap, she and the goddess Freyja may have been the same character at one point. Frigg’s day became Friday.

Saturday is the odd man out. In the West Germanic languages Saturday comes from the Latin “Saturni dies” or Saturn’s day, named for the Roman god Saturn. Around Scandinavia however, in Norse Germanic languages, Saturday is called by different variations of lørdag or laugardagur, which translates as Bath / Laundry Day.

Added info: The reindeer pair Donder & Blitzen from the Christmas story Rudolph the Red-Nosed Reindeer, come from the Germanic words for thunder & lightning.

Ghosts As Sheets

Ghosts represented as sheets come from the tradition of burial shrouds.

For most of human existence, unless you were wealthy, you weren’t buried in a coffin. Most people were buried in other ways and one of the most common was in a shroud or sheet of some kind (the original green burial). Coffins didn’t become common in Europe until the 18th century. So until then there were a variety of different kinds of shrouds but the basic idea was that the deceased was wrapped in cloth and lowered into their grave.

In this context, the idea of seeing a sheet/burial shroud walking about in the dark is terrifying. This is the origin of ghosts being portrayed as sheets – it’s from the understanding that a deceased person in their burial shroud was out of the grave and back from the dead.

Being buried in a shroud was a common practice in Europe and so, to see a shroud up and moving around, would have been a frightful sight.

Ghost Impersonators

In 19th century Britain impersonating a ghost by dressing in a sheet became both a prank fad and a real problem. At best a prankster would wear a sheet, run around at night, and generally frighten people in humorous ways. At worst it was a way to terrorize and assault women. There are even a few incidents of these “ghosts” frightening people out of their homes, leaving the house temporarily free to be burglarized (the original Scooby-Doo villains). It was also used in mid 19th century America by the Ku Klux Klan who pretended to be the ghosts of Confederate soldiers, come back to terrorize the people of the south.

This motif of ghosts being represented as moving burial shrouds/sheets found its way into entertainment by way of the theater in the late 19th century. The ghosts of the stage would be in white sheets, move silently, and generally do the spooky things we think of today. Early animated cartoons portrayed ghosts in a similar manner, most notably with Casper the Friendly Ghost (who is shroud-like).

Ghosts as burial shrouds underwent some stylization and became the lovable cartoon ghosts we see across pop culture.

Today the motif is fairly harmless and pretty ubiquitous. You see it in the iconic Ghostbusters logo, the ghosts in Pac-Man, Boo from the Mario games, the ghost mascot of Snapchat (aka “Ghostface Chillah”), Boo Berry cereal, the ghosts of LEGOs, Halloween Tootsie Pop ghosts, etc. The burial shroud ghost continues to live on.

Pain Medications: What’s the difference?

Common pain medications are similar but have a few differences, and generic drugs are just as good as brand names.

When looking for pain medication there are more than enough options to induce the paradox of choice. The key is in knowing what active ingredient will treat the problem you have. Most pain medications will treat basic aches and pains but they also have different strengths & weaknesses. The following are an introduction to the four most common active ingredients in most pain medications.

Aspirin is best used for:
• reducing heart-attack risk/severity (by thinning blood)
• mild aches & pains
• headaches


Not great for:
• more severe pain

Aspirin (acetylsalicylic acid)

Aspirin was the first modern pain reliever. An example of multiple discovery, both the ancient Sumerians as well as some pre-Colombian Native American tribes used the bark of the willow tree to relieve fevers & pain. Willow tree bark contains salicin which is metabolized into salicylic acid in the human body, something not understood until the early 19th century. Early synthesized versions of salicin were irritating to the stomach. It took until 1897 for the German corporation Bayer to begin mass producing a synthesized version known as acetylsalicylic acid that was kinder on the stomach. Bayer branded their product Aspirin and it quickly became the number one drug in the world.

Aspirin (when spelled with a lowercase “a”) has become the generic name for the active ingredient acetylsalicylic acid. The Bayer corporation “lost” their patent for the drug as a part of the fallout from WWI. Today it is the one of the most widely used medications in the world with about 120 billion tablets consumed each year. While it is used for pain & fever, it’s especially useful for a variety of heart problems.

Aspirin is best used for:

• reducing hear-attack risk / severity (by thinning blood), mild aches & pains, headaches

Aspirin is not great for:

• more severe pain

Ibuprofen is used for:
• aches & pains
• headaches (and hangovers)
• reduces inflammation and relieves arthritis
• reduces fever
• relieves menstrual cramps

Not great for:
• chronic headaches

Ibuprofen

Ibuprofen was developed by Dr. Stewart Adams in the 1960s as an alternative to aspirin for the English company Boots. Adams said he initially tested the drug on his own hangover. Boots sold the drug under the brand name Brufen but today ibuprofen is the active ingredient in a long list of brand name pain reliever drugs. It’s considered the best common pain reliever, better than aspirin.

Ibuprofen is best used for:

• aches & pains, headaches (and hangovers), reduces inflammation and relieves arthritis, reduces fever, relieve menstrual cramps

Ibuprofen is not great for:

• chronic headaches

Naproxen is best used for:
• very similar to ibuprofen but its effects last longer

Not great for:
• it takes longer to kick-in than ibuprofen

Naproxen

Naproxen is similar to Ibuprofen. While its effects take longer to kick-in they last longer. The effects of ibuprofen last 4-6 hours, naproxen’s effects last 8-12 hours.

Naproxen is best used for:

• very similar to ibuprofen but its effects last longer

Naproxen is not great for:

• quick relief because it takes longer to kick-in than ibuprofen

Acetaminophen is used for:
• bringing down a fever
• aches & pains
• headaches

Not great for:
• inflammation
 and joint pain

Acetaminophen (Paracetamol)

Acetaminophen can help treat pain and reduce fevers on its own, but it is also found in combination with other drugs such as in cold & cough medicines. While aspirin, ibuprofen, and naproxen are all nonsteroidal anti-inflammatory drugs (NSAIDs) and help treat inflammation, acetaminophen is not an NSAID and so it treats pain but not any underlying inflammation.

Acetaminophen is best used for:

• bringing down a fever, aches & pains, headaches

Acetaminophen is not great for:

• inflammation and joint pain

Go Go Generic

When you have decided which active ingredient you want relieving your pain the next question is if you should buy name brand or generic store brand. In short: buy generic.

When you buy a name brand pain reliever you are largely paying for marketing. In the United States a generic drug’s active ingredient is required by law to have the same strength as the brand name equivalent. It also has to work the same way in your body (it has to be bioequivalent). Also, like many white label goods, generic drugs are frequently made by the same company making the name brand equivalent.

First Sleep & Second Sleep

We sleep in cycles and adult humans aren’t designed for 8 uninterrupted hours of sleep.

Sleep Cycles

When we fall asleep we go from consciousness to unconsciousness, but within unconsciousness there are different stages to sleep. We descend from N1 (which is a very light sleep) to N2 (a restful sleep) down to N3 and sometimes even N4 (which are the deepest and most re-energizing stages). But we don’t just do this once, emerging on the other side wide awake in the morning. More like a roller coaster, we travel down from light sleep to deeper sleep and back up several times throughout the night. Each time we do this is considered a sleep cycle, we have about 5 sleep cycles per night, and each one takes between 60-90 minutes adding up to around 7.5hrs of sleep.

An example of one night’s sleep patterns. This shows 5 sleep cycles with 3 brief periods of awakening in the night.

At the end of the each sleep cycle, instead of going back to N1, we enter a very different kind of sleep known as rapid eye movement sleep (REM sleep) – from which the band REM is named. REM is so named because our eyes are moving around despite being closed. This is especially interesting because during REM sleep our eyes are on the short list of things that we actually can move. During REM sleep your body becomes paralyzed with the exception of your eyes, heart, and lungs. One potential reason for this is that during REM sleep we dream, and paralyzing our limbs is a safety feature that prevents us from acting out our dreams and possibly punching or kicking in our sleep. When REM sleep ends we either start a new sleep cycle or we wake up, but we don’t just wake up the next morning.

First & Second sleeps

While young children and teenagers can sleep uninterrupted throughout the night (and sleep longer), it is unusual for adults to do the same. We think we’re supposed to because we used to as kids, and society tells you to sleep for 8 straight hours, but to sleep uninterrupted throughout the night as an adult is fairly unusual. For millennia it was common practice to go to bed at sundown, sleep for about 4 hours, wake up for an hour or two, do some activities, and eventually go back to sleep for a few hours until sunrise. So instead of one period of sleep there were two, known as first sleep and second sleep.

What people did in this liminal time between first and second sleeps varied. Some would do the normal things of going to the bathroom or reading, but others might smoke, some might do some light house work, and some even visited neighbors from time to time. This waking period between sleeps was so common there were even special prayer books for these hours.

While in some more primitive tribes this idea of two sleeps is still common (such as in parts of Nigeria), this practice began to die out in the west in the 17th century. As people gradually pushed their bedtime back the time between sleeps grew shorter. At first it was just the wealthy, who could afford to burn more candles and stay up longer. Eventually larger cities began to illuminate some of the streets with lamps which extended waking hours for people of all classes. Coffee houses also became more popular in Europe during the 17th century which kept people wired for longer after the sun went down. But what really killed off first & second sleep was the industrial revolution of the 19th century. Through a combination of increased time spent in factories, gas & electric lighting becoming more prevalent, and a focus on efficiency, it became unfashionable to go to bed so early only to spend the middle of the night awake in activity.

A detail from the late 17th century Interior of a London coffee-house. Coffee houses kept people up longer at night, reducing the amount of time people spent between sleeps.

The next time you find yourself frustrated at being awake in the middle of the night when you “should” be asleep, you can reframe the situation knowing that your body might know better. Having a biphasic sleep pattern and waking up during the night is a normal part of human physiology. Choosing to be active in the middle of the night like your ancestors once did, is optional.

Imitation Eyes

Eyespot mimicry is used throughout nature to defend against predators

Mimicry is a useful method of disguise employed by a variety of species for both offensive and defensive reasons. Eyespot mimicry is frequently used defensively where a decoy set of eyes are used to help a vulnerable species. This is especially true of creatures lower down the food chain but you can find it higher up as well. Tigers have spots on their ears that look like eyes when they vulnerably lean over to drink water, giving the appearance that they’re still on the lookout.

Sometimes the decoy eyes serve as a scare tactic, such as in Batesian mimicry. The owl butterfly has owl-like eyes on its wings. It’s believed that in being able to flash the eyes of an owl the owl butterfly is able to scare small predator birds into thinking a large owl (who eats such birds) is present. In other species the eyespots are a distraction. In flashing a set of eyes a species can surprise & confuse a predator just long enough to escape. Some species use eyespots to draw attention away from their more critical body parts. The foureye butterflyfish for example has dark eyespots near its tail (which is less important) which draws attention away from its head (which is very important). When feeling threatened it can even swim backwards making its tail seem more like the head and vice versa.

Eyes looking out, for you

The northern pygmy owl of North America has eyespots on the back of its head, helping to mislead predators into thinking they are being closely watched. In 2016 an experiment was conducted in Botswana of painting eyes on the rumps of cows to prevent lion attacks. The cows with painted eyespots were less susceptible to predation by lion attacks than normal cows, as the lions may have felt they were being watched.

Finally, for those who believe in the supernatural malevolent force of the “evil eye”, you have some options of magical defensive eyespots. The nazar (a blue & white eye-like amulet) has been used for thousands of years from Turkey through to India and elsewhere. Similarly the hamsa (which also features an eye but sitting in the palm of a hand) has been used around the Middle East for a similarly extended period of time.

Both symbols are said to attract the negative energy of evil eye attacks, and destroy/repel them. If your nazar is cracked then it’s “proof” that it has worked, and of course you’re supposed to buy a new one. After all, you have to keep your magical eyespot functional.

Left: the hamsa. Right: the nazar.

Amish “Miracle” Fireplaces

Amish built mantles added to Chinese space heaters

In print and online you may stumble upon advertisements (that frequently look like news articles) for the Heat Surge, the “miracle heater”. These ads heavily imply that the heaters are being brought to you by the Amish. Sometimes the deal is that you get the heater for “free” if you purchase the Amish built oak mantle to go with the heater. They range in price from $330 to $600 and use technology from the “China coast” according to the Heat Surge website. The secret to their power is their “Fireless Flame® technology”. Of the numerous questions one may have, one question is: how is this happening?

The Amish, famous for their aversion to electricity, are not developing electric space heaters. Their involvement is in the production of the oak mantles that encase the heaters. As for the “miracle” heaters, they’re nothing more than 1500 watt electric space heaters made in China. Search your local big-box store and you can find comparable 1500 watt space heaters but with price tags as low as $50. That said you would be losing out on the opportunity to partake in a “miracle”.

Fade to Black … and Blue

Printed materials fade to black and blue because black and cyan ink are more resistant to the sun’s short UV waves

When you have a poster, a newspaper, or some other printed material sit in direct sunlight, the colors fade over time and frequently you are left with a mostly black & blue print. Colors fade for a variety of reasons (humidity, the type of paper, the types of inks, the temperature, etc) but exposure to light, and in particular ultraviolet light, is the primary reason.

The electromagnetic spectrum accounts for photons with a variety of wavelengths – from the very short (gamma waves) to very long (radio waves). The portion of the spectrum we can see with our eyes is known as visible light, which accounts for all the colors of the rainbow. Blues and violets are shorter wavelengths than yellows and reds. Sitting just beyond the blues & violets is ultraviolet (UV). While blue and violet are visible, ultraviolet is invisible. UV wavelengths are just a bit shorter than what our eyes can perceive. UV wavelengths are also dangerous.

When ultraviolet waves from the sun hit printed materials their short wavelengths can break the chemical bonds of the colored inks. The more damage to those chemical bonds the less those printed colors are able to continue reflecting the wavelength of their particular color. The typical printing process uses 4 colors: cyan, magenta, yellow, and black. Cyan (blue) reflects the relatively short wavelengths to make the color blue and as such it is better equipped to resist the even shorter wavelengths of UV. What we see as “black” is frequently a dense combination of ink colors (including black ink) and so it takes longer for this combination of inks to fully breakdown (although it will start to shift and lighten in color). Yellow and magenta however are forced to absorb shorter wavelengths and only reflect the longer wavelengths that are their colors. As such, the yellow and magenta in a printed poster tend to fade faster because more ultraviolet light is being absorbed and breaking down the chemical bonds of those inks.

This is why printed materials sitting out in the sun for too long will commonly lose their warmer colors faster than their black and blue colors.

Added bonus: The Earth’s atmosphere blocks a lot of UV waves from the sun, but some still enters our atmosphere. Because the moon’s atmosphere is too weak to block the sun’s ultraviolet waves, the American flags planted on the moon are all white at this point after decades of ultraviolet exposure has faded all of their colors away.

The Ambassadors & Anamorphosis

The illusion hidden in the middle of an art masterpiece

In 1526 German painter Hans Holbein the Younger went to England in search of work. Eventually he found a client in Anne Boleyn (wife number 2 of Henry the VIII, and mother of Elizabeth I). By 1535 he was the King’s painter, creating portraits and documenting courtly life. It was through this life at court that he came to paint one of his most famous works, the double portrait of French ambassador Jean de Dinteville and French bishop Georges de Selve titled The Ambassadors.

The Ambassadors by Hans Holbein

Painted in 1533, The Ambassadors is a meticulously detailed masterpiece of Renaissance art. At the time it was painted, Henry VIII was separating the English Church from the Catholic Church of Rome, and these two ambassadors were most likely trying to resolve this political & religious turmoil. Filled with symbolism and hidden messages, the painting is more than just a double portrait. Between the two men is a table crowded with objects. On the top shelf are instruments to study the skies and on the lower shelf are items associated with the Earth and human activity. The lute with a broken string, the book of mathematics opened to division, and the hymn book are all references to the political & religious discord taking place at the time.

It’s what’s below the bottom shelf that makes this painting especially famous. With the top shelf representing the heavens, the bottom shelf representing life, then what is this thing below that? When viewed head-on it is a long diagonally shaped blob that looks out of place in this very life-like painting. However, when viewed by standing at the edge of the painting’s frame (or tilting your device), through a distortion of space, it is revealed to be a skull. The skull as a reminder of death completes the three levels of the center of the painting with the heavens, life, and finally death. It is also interesting that death exists amongst life but can’t be seen properly. It can only be viewed when you can no longer view the rest of the painting (when you can no longer view life).

Through anamorphosis the warped image in the center of the painting is revealed to be a skull when viewed from the right perspective.

Anamorphosis

The skull at the center of The Ambassadors is one of the most famous examples of anamorphosis. In anamorphosis an image can only be properly seen from a certain point of view, or with the aid of a special device (such as a mirrored cylinder), or sometimes both. It’s an illusion where you start not understanding and then move into understanding. Unlike normal optical illusions or trope l’oeil which can be understood (albeit mind bendingly) at face value, anamorphosis can only be understood when viewed the right way.

It’s a neat optical trick that has been used in various ways for millennia. The technique goes back at least as far as the ancient Greeks, but it really came into being in the Renaissance. Leonardo da Vinci included an early example in the illusion known known as Leonardo’s Eye. It was also used at times with tromp l’oeil to create more elaborate church ceilings. This was the case when Andrea Pozzo painted a “dome” on the ceiling of Saint Ignatius’s in Rome because the church builders were not allowed to construct an actual dome. So if you stand in the right spot the illusion of looking up into a dome is excellent, but from any other angle the illusion breaks down.

Saint Ignatius’s in Rome has a fake dome done through anamorphosis and trope l’oeil.

Today we find anamorphosis in fun street art. Sidewalks become filled with precarious holes or cliff faces that confuse our sense of space. Artist Jonty Hurwitz creates anamorphic sculptures including a three dimensional version of the skull from Holbein’s The Ambassadors. In practical usage we experience anamorphosis most frequently while driving. Words written in the road are elongated but look correct from the vantage point of a seated driver. Similarly emergency vehicles such as ambulances frequently have words written backwards, but when seen from a driver’s mirror they read correctly.

The Missing Children of Hamelin

It is very likely the Pied Piper is based on real events

The basic story of the Pied Piper of Hamelin is that in 1284 the Medieval German town of Hamelin had a rat problem. A stranger came to town who claimed that, by playing music on his magic pipe, he could lure the rats to the Weser river and rid the town of its problem. He did so and afterwards when he came to collect his payment the town decided they weren’t going to pay the agreed amount. The piper exacted his revenge by using his pipe to lure 130 children of Hamelin away from the town where they were never heard from again. As fairy tales go it’s pretty … grim.

In the early 19th century this version of the story was recorded by the Grimm Brothers of Germany who documented various Germanic fairy tales that were part of the oral storytelling tradition. Unlike most of their fairy tales however, the curious thing about the Pied Piper is that it seems to be only partially fictional.

Not a normal fairy tale

For being a fairy tale, one of the first curious things about the Pied Piper of Hamelin is that it takes place in a real town, not a fictional location. Also, unlike the standard “a long time ago” or some other vague time frame, this story very specifically took place in 1284. Before the Grimm version, the earliest documented version of this story is in the stained glass windows of the church of Hamelin around 1300. The church was destroyed in 1660 but details of the church, its windows, and the story of the missing children were, by then, documented in several places. The Hamelin records of 1384 say that, for reasons not specified, 130 children of Hamelin left in 1284 and never returned.

What happened to the children of Hamelin?

While the stained glass windows documented the loss of Hamelin children they never mentioned a piper. The earliest documentation of a piper is the Lueneburg Manuscript of 1440-50. So for over a hundred years the story may have had no piper, just missing children.

At face value the idea that a piper used music to lure rats & children out of town is unlikely. That said there were instances of dancing mania in the Middle Ages, where groups of people would just start dancing as in some sort of mass psychogenic illness. Perhaps a musician initiated some mania that led the children away.

Another theory involves the rats and that the children may have died from bubonic plague or some other infection spread by rats. Here the piper goes from being a musician or magician, to becoming a rat catcher. This theory is unlikely though because, to start, why would a disease only kill the children the town and not the adults as well? More importantly, the rats didn’t become a part of the story until 1559. So for almost 300 years the story had already been told without rats.

Still another theory is that the children left on the failed Children’s Crusade of 1212 where children of Germany & France were said to have set out for the Holy Land to try and peacefully convert the Muslims to Christianity. The piper in this case would have been someone whose job was to recruit children to join the crusade. Then the children never returned because they were sold into slavery. But because of the differences in years, and that the Children’s Crusade is riddled with fictional details and inaccuracies, it seems unlikely like that this is the explanation for the missing children of Hamelin.

Perhaps the most likely explanation is found in German colonization efforts. By the 13th century there was a push to have Germanic people move eastward to colonize more land from Poland down through Transylvania. The term “children” could have been meant more as “people of the town” rather than actual little kids. In this sense these were adults who moved away from Hamelin to settle new lands. The piper in this case could have been some loudly dressed smooth talking recruitment agent who came to town to sell people on the idea of emigration. This colonization theory is supported by a documented trail of late 13th century Hamelin family names appearing in Eastern European areas. Similarly, German place names start to become the names of towns in these areas around the same time.

So rather than a magical story of children being lured away from town by a mysterious piper, the reality may be that some citizens of Hamelin decided to leave and move eastward. As a way to remember these expatriate friends & families the town commemorated the loss in stained glass and in a story (a story that got confused and changed over the years). If only they had commemorated why they left.

Added info: “Pied” means “multicolored”, so he was a piper wearing somewhat eccentric/eye-catching multicolored clothes.
