August 24 - Mt. Vesuvius Erupts! Pompeii Buried!

   Posted on August 24, 2022     

This is an update of my post published on August 24, 2011:




On this day almost two thousand years ago, the Roman cities of Pompeii and Herculaneum were destroyed—flash-fried, and then buried—by heat, ash, and pumice from a volcanic eruption.

Luckily, most of the people of those two ancient towns were able to flee when the volcano showed signs of erupting. There are estimates that 2,000 out of about 15,000 to 20,000 people died. In other words, about 10% to 13% died, and between 87% and 90% fled to nearby towns or even farther.

Still, even the folks who lived lost their homes and probably most of their possessions.


Some wonder why people would live so close to a dangerous volcano—but Mt. Vesuvius had been dormant (inactive) for hundreds of years before this eruption.

It is sobering to realize that, although Pompeii and Herculaneum were never rebuilt, people still do live near Mt. Vesuvius! There are almost one million people in the nearby city of Naples, and another two million living elsewhere are close enough to be in danger if there were a really big eruption.

And that is possible. Vesuvius is definitely not extinct, and it's not even dormant.


Instead, scientists consider Vesuvius an active volcano. It has erupted again and again (although not as strongly) since the 79 C.E. eruption: fifteen times between the years 79 and 1000 C.E., eight more times in the next 500 years, once in 1500, again in 1631, six times in the 18th century, eight times in the 19th century, and in 1906, 1929, and 1944!

No wonder scientists consider Mt. Vesuvius to be one of the most dangerous volcanos in the world!


Although it is incredibly sad that so many people died in Pompeii and Herculaneum, it would be even more sad if we hadn't discovered their remains. Buried beneath six meters (18 feet) of ash and pumice, Pompeii was actually forgotten for almost 17 centuries! In the 1700s, the city was accidentally rediscovered, and archeologists got busy excavating the buildings and the remains of humans and other animals.

During the 1800s a man named Giuseppe Fiorelli realized that the occasional open spots in the ash layer were holes left by decomposed bodies. He injected plaster into the holes to perfectly recreate the people or dogs—even the terrified expressions on their faces. This technique has not given us a freeze-frame picture of what people did in their daily lives, because of course people were trying to escape death or sheltering in buildings. Still, scientists have excavated many different tools and instruments, frescoes (murals) and toys—all of which have helped them recreate what daily life must've been like at that time.

December 21 - Anniversary of a Solstice Eclipse

 Posted on December 21, 2021


This is an update of my post published on December 21, 2010:




A fairly rare event—the total eclipse of the moon—and a once-a-year event—winter solstice—happened on the same day on this date in 2010.

On that day, I wrote: "Here in Southern California, we seem to be living at the bottom of a very big shower stall right now, because it's been raining HARD for days. (I know many people have to deal with this much rain on a regular basis, but we're used to drought and earthquakes, not flooding and inundation!) ...The point is, we couldn't see the eclipse because of the total cloud cover."

A total lunar eclipse is when the Earth gets between the Moon and the Sun, and the Moon falls totally within Earth's shadow. The Moon, which is full or nearly full, usually shines (reflecting the Sun's light) a bright white color, but during an eclipse, the moon seems to become gray, then orange, then deep red.



Here are some photos of a more recent lunar eclipse,
all put together into one photo so we can see the
changing color of the Moon.


The winter solstice is the shortest day of the year—and, of course, the longest night. Most cultures nowadays count the winter solstice as the day that winter begins.


NOTE: Most of the world's population lives in the northern hemisphere. However, millions of people live in the southern hemisphere, and today is their SUMMER solstice—the shortest night and the longest day of the year!


How do (and have) people celebrate(d) the winter solstice?

Germanic countries (including the Scandinavian countries), long before Christianity in Europe, held a winter festival called Yule or Yule-tide during the solstice. Customs such as burning a Yule log, decorating the house with evergreen branches and wreaths, lighting candles, eating a Yule feast, and Yule-tide singing (or Wassailing)—all of these solstice customs are now commonly associated with Christmas. Characters that haven't made it into widespread use in Christmas traditions include the Yule goat, pictured here:

 
Yule Lads, from Iceland's Yule celebrations, haven't caught on in the U.S. - except maybe they have, in the form of elves and gnomes?




A Druidic tradition (think of the people who built England's Stonehenge) calls the winter solstice “Alban Arthuan,” which means Light of Arthur, or “Alban Arthan,” which means Light of Winter. A poetic interpretation of the Light of Arthur is that the legendary figure of King Arthur (of “Knights of the Round Table” fame) still sleeps in a mountain, ready to return to his people if he is needed. The Druidic holiday colors are red, green, and white—again, colors that today are often associated with Christmas.



Ancient Rome celebrated Saturnalia for a week around the solstice. There were some nice aspects of the holiday—wars were interrupted by temporary truces, for example, and slaves were served by their masters—and there were some familiar customs such as exchanging gifts and lighting candles. However, apparently the holiday eventually started to become less fun, with too much wild behavior and even crime.


Other places in the world celebrate the solstice with bonfires, ritual baths and purification rites, feasting, and even special dances.

Special places for celebrating the solstice...

  • Newgrange is a beautiful megalithic site in Ireland, with a huge circular stone structure estimated to be around 5,000 years old (older, even, than the Egyptian pyramids at Giza!). It was built so that a shaft of sunlight would illuminate a particular special spot on the dawn of winter solstice.



(By the way, a megalith is a huge stone used to build a structure or monument.)

  • The Sun Dagger of Chaco Canyon, New Mexico, was built about a thousand years ago. A modern-day artist noticed that, during the summer solstice, a slender beam of sunlight passing between two rock monoliths exactly bisected a spiral-shaped symbol. She came back to the spot on the winter solstice and, sure enough, a ray of sunlight bisected another, smaller spiral. Unfortunately, so many people have gone to see the sight of these daggers of sunlight, the trail eroded, the monoliths shifted, and the Sun Daggers no longer bisect the spirals!




  • The Great Zimbabwe in sub-Saharan Africa may have helped medieval astronomers track celestial bodies; modern-day scholars note that the brightest stars in Orion line up with several monoliths during the winter solstice.
