September 6 – Sails and Salem


Posted on September 6, 2016

For any given day in the year, we can find many and varied events that happened on that day in years (even centuries) past.

Here are a few that fit together nicely:

On this date in 1492, Christopher Columbus sailed away from the Canary Islands. This was the last of the known ports of his famous voyage – it was the beginning of the Great Unknown.

On this date in 1522, the only surviving ship of Ferdinand Magellan's round-the-world journey returned to a port in Spain. On that day the Victoria became the first ship to circumnavigate the world!

On this date in 1620, the Pilgrims sailed away from Plymouth, England, on the Mayflower. The goal of this so-famous voyage was to settle in North America. Eventually, they settled in what they named Plymouth, Massachusetts.






And on this date in 1628, the Puritans settled Salem, Massachusetts.

All of these have in common the courage to face the unknown. The courage to sail off, discover and explore, or the courage to start new lives in new places.

Unfortunately, they also have in common a ruthless disregard for peoples of those newly discovered, explored, and settled lands.


I always enjoy exploring the surprising, confusing, or memorable aspects of familiar historical tales. Here are a few:

  • There is a myth that Christopher Columbus went up against the people of his day, claiming that the world was round when “everybody knew” that the world was flat. The myth goes on that Columbus was proved right – the underdog wins the day!

    There is another myth that Christopher Columbus was incredibly stupid and wrong-headed about the world. According to this myth, everyone knew that the world was round like an orange, and learned people agreed that it was really, really huge. According to this story, everybody knew that sailing across the Atlantic Ocean to China and “the Indies” was impossible, at least at that time – the distance was too far. According to this myth, Columbus stubbornly argued that the world was way smaller than it is – and he was just plain lucky to run into islands and continents conveniently located a sail-able distance from Europe.

    The reality was that experts, scholars, and navigators in the late 1400s all agreed that the world was roundish (if you want to see how even ancient scholars knew that, check out
    this article), but they disagreed about its size and shape, and they of course didn't know how much of the Earth was covered by land and how much by oceans. Columbus thought it likely that the Earth was smaller than it is, and that it was shaped more like a pear than an orange. But he was hardly alone in these thoughts – he wasn't someone who held onto a stubborn disbelief of well-established knowledge. A mathematician named Paolo Toscanelli, from Florence (now Italy), thought that Asia could be reached by sailing west – and Columbus corresponded with him. A globe made by Martin Behaim showed Asia extending much farther east than it really does, and the Atlantic islands including the Canary Islands extending much farther west than they really do; even the great (and ancient) thinker Ptolemy thought that Eurasia is much larger than it is.

So, the more correct view of Columbus is more nuanced. He certainly wasn't a great intellectual hero whose minority views were proved correct! But neither was he a know-nothing fool who ignored all the experts of his day.

  • You may have read that, even though Magellan is often given credit for being the first person to circumnavigate the globe, he didn't do it. He was killed in what we now call the Philippines, before his mission even reached “Spice Islands” (today called Indonesia). 

Magellan deserves some partial credit, since he organized the voyage, navigated the dangerous, stormy straits that bear his name around the tip of South America, and also navigated a 98-day journey across the Pacific before reaching habitable land...but two others also deserve credit:
The Basque mariner Juan Sebastian Elcano commanded the return voyage of Victoria, which was the only surviving ship out of the five that started.

Henrique
And Enrique, a personal slave of Magellan's who acted as an interpreter during the expedition, had lived in the Philippines, and historians point out that he may be the first human to have circled the globe – when the expedition reached the Philippines, his homeland!

It's interesting to note that, although most of the sailors of the Magellan expedition were Spaniards and Portuguese, the crew included men from Greece, Sicily, England, France, Germany, and North Africa. I don't know if Enrique was the only slave, or the only Asian-born person on the ship – but it's clear that the expedition was more multi-cultural than we generally picture it!


  • What is the difference between the Pilgrims of Plymouth, MA, and the Puritans of Salem, MA?

Both groups were religious Christians who believed in Calvinism (which is one of so very many Christian branch-offs).

But the Pilgrims were a separatist group who felt that they needed to separate from the Church of England. They fled from England and settled in Holland, in the Netherlands, but they feared that they might lose their English cultural identity there, so they fled even farther...all the way to the New World.

Many Puritans, on the other hand, remained within the Church of England and sought to reform it (purify it) from within. Some of these “non-separating Puritans” founded Salem and, later, created the Massachusetts Bay Colony.


(By the way, some sources make it sound as if Puritans and Pilgrims were two different groups, and other sources clearly state that Pilgrims WERE Puritans; they say that Pilgrims were a minority group of separating Puritans.)

September 12 – Anniversary of a Cave Discovery

Posted on September 12, 2015

This photo shows two of the four
teenaged cave discoverers, plus
two of the adults they consulted about
how to keep their discovery safe.
What do you suppose four French teenagers discovered, on this date in 1940, that became of enormous interest to scientists, historians, and tourists alike?

If your answer is “a cave,” you're half right.

They discovered some cave paintings!



Paintings that were created about 17,300 years ago!

The early humans who created the art in Lascaux Caves mostly painted animals, but they also painted abstract signs. They did not paint trees or other plants, and they didn't paint landscape.

There are almost 2,000 different figures and signs on the cave walls, and almost half of them are animals. We can guess that animals must have been very important to these hunter-gatherers!







Lions and horses and bears, oh my!

Here are some of the creatures painted on the cave walls:

364 horses (or equines)


90 deer (or stags)


around 25 cattle and 25 bison


7 big cats

1 bear

1 wooly rhinoceros


1 human and 1 bird


Human-hand stencils are far more
common than images of entire
human figures.
Many of the painted figures look like animals but cannot be positively identified as a particular kind of animal. Strangely enough, there are no pictures that look like reindeer, even though we know from archeological evidence that reindeer were these Stone Age people's main food!

One of the rooms has four images of black bulls, or aurochs – one of which is huge! At 17 feet (5.2 m) long, this is the largest animal ever found, before or since, in cave art.

Lichen and fungus and mold, oh my!

If you know anything about France in the 1940s, you know that Hitler and his Nazi army was making the nation a very unsafe place to be. But news of the the teenagers' discovery of cave paintings still spread like wildfire, and many people came immediately to see the paintings. The boys right away started charging 40 cents per person to see the cave. A trusted teacher told the boys that it was imperative that they not allow visitors to go alone into the cave, and that they not allow people to touch the paintings. As a matter of fact, he told them that they should guard the cave day and night.

Three of the boys returned to school after their summer vacation was over, but the youngest boy, Jacques Marsal, pitched a tent at the cave's entrance and really did guard it day and night! He became the main tour guide as well as the security detail - and he served in this way FOR THE REST OF HIS LIFE!!!


It wasn't long after the World War II that the Lascaux Caves were opened to the public for professional, commercial tours. (Still utilizing Marsal as a guide!) At that point, the number of visitors jumped to more than a thousand people per day!

Unfortunately, as you might guess, more than a thousand people a day introduced a lot of contamination into those caves! The heat and humidity of all those people affected the cave environment, and even the carbon dioxide breathed out by all those people made a difference! Soon scientists could see that the pigments used in the paintings were breaking down – and, even worse, lichen was growing on the walls!

As Rick Steves says, the cave paintings deteriorated more in 15 years than it had in the 15 THOUSAND years before that!


The caves were closed to the public in 1963, but scientists and preservationists were still allowed to visit the caves. Since 1998, however, black mold (a kind of fungus) has been growing in the caves. In 2008 authorities closed the cave even to the experts – only one scientist could enter the cave for 20 minutes per week to monitor conditions in the cave.

Apparently the battle with the fungus is far from over, but at this point a few scientists are allowed to work inside the cave for just a few days out of every month.


Lascaux II...and III...

A careful copy of two of the most interesting rooms' worth of cave paintings have been painted onto the walls of a nearby cave. Visitors are allowed to view these paintings – with no additional harm for the originals!

I read that an even more careful replica is being made of yet another room, the Nave of Lascaux, using laser technology to project the Paleolithic images onto layers of polystyrene.




Why cave paintings?

Anthropologists still do not know (and may never know) why so many Paleolithic (early Stone Age) humans all over the world have painted the walls of caves. Many cave paintings are located deep in caverns, in rooms that are hard to get to, and there is no evidence that people actually lived in the rooms that are decorated with these paintings. That's why many scientists think that the paintings might have ceremonial and/or religious purposes.

The earliest known cave paintings are at least 35,000 years old; these are located on one of the islands of Indonesia. Cave paintings have been found in Africa, North and South America, Australia, Europe, and many parts of Asia. I hope you realize that that means all over the world, since humans never lived in Antarctica (at least not until scientists opened research stations there in the mid-1950s).

I read that Paleolithic people probably produced more rock art in the open air than they did in caves, but only six sites of open-air Paleolithic art have survived until the modern age. So cave art is probably not typical of Stone Age humans, but far more cave art has survived!

August 3 – Anniversary of the "Discovery" of the La Brea Tar Pits

Posted on August 3, 2014

Lovely green grass... a boulder here or there, half submerged in the earth... a patch of weeds over here, a patch of bare dirt over there, a patch of—

Wait!! What is THAT?

It's black. It's sticky–yicky, oozy–squoozy. It's even bubbly!

It's tar!

My sister used to live just a block away from the La Brea Tar Pits, in Los Angeles, California. And not all of the tar is safely fenced off from us modern humans walking around Hancock Park. As we walked along, we often saw sticky patches of fresh tar bubbling up here and there!

It was quite...unnerving!

You know that there is petroleum, or oil, underneath the ground in some places, right? Well, that is the case in some areas of Los Angeles. Some crude oil has been seeping up to the Earth's surface through cracks in the crust; once exposed to the air and sun, some of the lighter components of the oil has been evaporating away. The denser part that is left behind is called natural asphalt, or tar.

The pools of tar have been growing (and sometimes shrinking) over tens of thousands of years. And over the years, the pools have been accumulating a dusting of dust and dirt and a partially covering of leaves and other natural debris. And over those thousands of years, many animals have stumbled into the pits, where they found themselves stuck. Naturally, some predators that saw the stuck animals decided to get an easy dinner—but then they also got stuck!

On this date in 1769, a Spanish friar named Juan Crespi noticed and wrote about the pools of tar—and he is the first person we know saw them. (Obviously, many native Americans must have seen the tar pools at one point or another—but we don't have records that tell us who or when. That is why Crespi gets the label “discoverer,” when really he was probably the first European person—not the first person—to discover the tar pools!)


Did you know...?

  • La Brea means “the tar” in Spanish. So the name The La Brea Tar Pits translates to “The The Tar Tar Pits.”
  • The tar not only killed a lot of animals, it preserved their bones as fossils. At the La Brea Tar Pits there is a museum in which many of the more than 1,000,000 fossils found in the pits are displayed. The species found include more than 150 species (kinds) of plants and more than 460 species of animals.
  • Only one human skeleton has ever been found in the La Brea Tar Pits—a woman who lived and died around ten thousand years ago. There is evidence that suggests that she was deliberately submerged in the tar pit only after she died. In other words, the tar didn't kill her; instead, she was buried in one of the pools.
  • Jose Longinos Martinez wrote in 1792: “Near the Pueblo de Los Angeles there are more than twenty springs of liquid petroleum, pitch, etc. Farther to the west of said town . . . there is a great lake of pitch, with many pools in which bubbles or blisters are constantly forming and exploding. They are shaped like conical bells and, when they burst at their apex, they make a little report.”
    (In this case, report means an explosive sound.)
  • There have been more than 60 tar pits excavated by scientists, although only about 12 were found to hold a lot of fossils.
  • There have been no dinosaur bones discovered in the tar pits. The dinosaurs died out millions and millions of years before the pools of tar formed.
  • The bones found in the tar pits include mammoths, dire wolves, short-faced bears, saber-toothed cats, and giant sloths.
