5/15/23 Report - Stunning Finds In Surprising Locations. Water Up or Sand Down. Perception and Illusions.

In a stunning discovery, a three-thousand-year-old ancient Egyptian figurine of the god Osiris has been unearthed in a former Nazi SS hospital in the Lublin province.

The figurine is part of a long-lost collection of antiquities that has been the subject of a search by specialists for decades...


Finding ancient Egyptian and Roman antiquities in Poland is highly unusual. Therefore, after the discovery last year, the objects needed to be thoroughly analysed.

“Such an unprecedented find in our area raised doubts about the authenticity of the relics," the Lublin voivodeship heritage protection office reported.

A few days ago the heritage protection specialists were finally able to announce the discovery as genuine.

Here is the link for more about that.


Egyptian figurine sensationally unearthed in former SS hospital – The First News

It isn't easy to determine the age or source of finds.  Things are moved.  You can find something a hundred years old that was just lost yesterday or two days ago.  Things can get carried around and lost multiple times.  I could go out and lose something tomorrow where it has never been and where there is no reason that it should be.  There will be surprises.  Things will be found where you would never expect them.

In the past I talked a lot about how sand and other objects move on a beach.  That is an important topic if you are a beach detectorist, but every detectorist will benefit by understanding that.  You get erosion everywhere, but some places more than others.  Erosion is quicker, more massive and more constant at the beach than most other places.

We are always interested in where coins will be found.  Obviously, if a coin is covered by too much sand, the metal detector won't detect it so hope for coins to be uncovered or exposed.

When looking at a beach you scan a large area.  It can be difficult to tell by such a visual scan how high or low the sand is and it will vary from place to place.  Cuts are easy enough to see, but it is not so easy to tell how high or low the overall surface of the beach is by just looking at an expanse.  You can measure the height of the sand relative to stable objects such as sea walls, posts or rocks, but without such markers it is difficult to judge.

Perception and language are both very imprecise.  We say the sun rises in the morning, for example, but  it would be more accurate to think of the earth as rotating.  It appears that the sun rises though.  As we see it, the sun appears to rise relative to the horizon.  Perceptual processes are complex, and there are a numerous well known optical illusions.  One illustration that I mentioned before is the Muller-Lyer illusion.  

Which of the horizonal lines shown below is the longest?  Don't include the arrow heads or fins.  Just the horizontal lines.


Most people will say the bottom one is the longest, but if you measure the horizontal lines, you'll find they are equal.  Perhaps the following illustration will clarify that.


Here is another one.  The moon looks much larger when it is near the horizon.  Various explanations have been offered by why that is, but if you see the moon when it firsts "comes up" it will look much larger than when it is high in the sky.  When the moon is low you are looking through more atmosphere and you probably compare it to other objects on the horizon.  I think it also has to do with the fact that people tend to have a conceptual model of the sky as a being dome-shaped and relatively close.  Take a photo of the moon and unless you have some good magnification, it will appear disappointingly small.

When you look at a beach, it is difficult to determine if the water is higher or the sand is lower at any particular area.  If there is a seawall (or something like that) and one day when you arrive you see the water is all the way to the seawall or dunes when it hasn't been that far back for a long time, your first conclusion might be that the water is higher even if what really happened is the sand in front of the landmark was lower, which allowed the water to proceed farther back.  The water might be deeper there because the sand was removed.  At another area not far away, at the same time it might look like the lower because the sand has accumulated at that location. It isn't easy to tell which is the case without some good point of reference.

I know I've misjudged conditions like that before.  I know there have been times when I saw the water in and thought it was a high tide when it was actually a loss of sand that I was seeing. 

A small angle can make a huge difference over a large expanse of the beach.  The beach is irregular and the slope and contour of an expanse of beach can be very difficult to judge.
