The Sun Stands Still


Winter Solstice, 2013 - digital - 2013, DS 


Well, I'm a little late with this post; technically the sun "stood still" yesterday, the day of the winter solstice, but I spent the day working on the image above. This all came about when I rediscovered a little rock in the glove compartment of my car - one of my beach finds, probably picked up off a sandbar around the time of this year's summer solstice.

It's an enigmatic little rock... which looks as if its flat surface has lines carved into it. But, if that's actually the case, then it's only a small portion of something much larger. Who knows? But, in its own understated way, it kind of brings to mind the larger - and more celebrated - mysterious rocks that cover the globe, which are thought to be directly related to the winter solstice; Newgrange in Ireland, for instance.

Known to the druids as Alban Arthan, and the beginning of Yule, the winter solstice marks the time of the year when the sun returns, and the daylight hours slowly begin to grow longer... which is a good thing to know as we drag ourselves through the ice and snow!

Anyway, my little rock wanted to be a star... and so, I made it one... scanning it into this machine, and positioning it with an old scan of some ice I had on hand. (Yes, you can scan ice on a flatbed scanner... but, be quick about it!)

So, take heart... the winter has just begun, but, the "darkest hour" is already history!

Anthracite Coal & Graphite

I guess I feel obligated to finish my "Black Rock" series (started here & continued here). So, here's the "big reveal".

Well, it's like this: one can't write on a hard, granulated surface with obsidian... however, with anthracite coal you can. Which is how I now know that all my mysterious black rocks - despite how iridescent and pretty they may be - are, in the last analysis, anthracite coal. The ones with a more silvery sheen, however, make finer, more pencil-like lines, which sent me on a google search for graphite; apart from being pencil lead, I never did know exactly what it was.

Actually, the game was really given away when I found the anthracite slab above... which is glassy in the center, but, the surface of which is similar to a shimmery black poster board. Whatever it was, it wasn't obsidian.

(Note: It was also easy to pry apart in layers... and, though I still hadn't concluded it was coal, I still half-expected to find a fossil. In reality, one can find fossils in slabs of coal... and, two things on my "bucket-list" are: finding a meteorite, and finding a fossil!)

Anyway, I now know that anthracite coal is a mineral and the high-carbon metamorphic state of bituminous - ordinary household - coal. Interestingly, anthracite may be considered to be a transitional stage between ordinary bituminous coal and graphite, the latter often considered to be meta-anthracite and/or the last - and purist - metamorphic stage of coal.






Well, yeah, I guess I had hoped my mystery rocks were obsidian... but, anthracite and graphite are not the lowly, mere utilitarian minerals one might expect. Anthracite was a common replacement for jet in all that wonderful Victorian mourning jewelry... and it's been carved into sculptures as well. And, the same goes for graphite! The two beautiful figures above - the hand and shell (above, left) - were carved from graphite by Angelio Batle, found here, along with a number of others. And the graphite quill (above, right) is just one example of a whole series of really cool, carved graphite pencils (one can write with!) for sale here.

And, so ends the tale of the mysterious black rocks... ;-)

A Day at the Beach


3 scans of a found object - 2013, DS (click to enlarge)



"Shinto teaches that everything contains a kami (神 "spiritual essence"),
commonly translated as god or spirit).

The kami reside in all things, but certain places are designated for the interface of people and kami (the common world and the sacred): sacred nature, shrines, and kamidana. There are natural places considered to have an unusually sacred spirit about them, and are objects of worship. They are frequently mountains, trees, unusual rocks, rivers, waterfalls, and other natural edifices. In most cases they are on or near a shrine grounds. The shrine is a building built in which to house the kami, with a separation from the "ordinary" world through sacred space with defined features based on the age and lineage of the shrine."

- excerpt from the Wiki entry for Shinto




High-tide is not the most excellent time for beachcombing, but, neither is the blistering heat of mid-day. So, for my first visit to the shore in a very long time, I chose the hour just before sunset for my foray by the water's edge. There were a few people milling about on the sand, but, like any dedicated beachcomber, I ignored them completely, aware only of their voices drifting around me in the air, in that peculiar way sound is both muffled, amplified and scattered by the ocean's waves.

I saw only one other person by the water - a woman, perhaps Muslim, swathed in black veils, hunched down in the encroaching waves. She was staring at the horizon, her hands folded under her chin in a way that may have been praying. But, as I approached, she stood up and slid off in the opposite direction.

Communing with the ocean is often - and needfully - a very private thing.

I found very little... the beach isn't what it used to be, or, maybe I'm not what I used to be, lacking the awe and raw enthusiasm I had as child, when everything still seemed new and mysterious.

But, I did find one thing... it was sitting in the sand in the path as I was leaving... a rock, but a special rock, in that it was a chunk of beach marble, my favorite sort of rock, and one that I had collected in the past; a collection I had to part with during the course of moving a few months ago. It was like greeting an old friend, but, before snatching it up, I looked around to make sure I wasn't stealing someone else's treasure.

Anyway, above are scans of three faces of the found object. It isn't as silky-textured as the specimens I've found in the past, those of which have been smoothed and sanded by the salt-water for a longer period of time... (and, an example of which is posted below... my only remaining touchstone of that species). But, it's easy to understand why marble is so often the choice of sculptors. Maybe it has something to do with metamorphic process that marble has to go through, it's physiological history, that speaks to the artist. Or, maybe some rocks just happen to "speak" a little more eloquently.

Interestingly, the grey, striated beach marble I find, tends to have one or more roughly pentagonal faces; the pentagon - along with the hexagon - being a favored shape in the organic world, and for the sacred geometer and mason, a symbol of sentient life.

In the Disneyland world of a child's mind and the "primitive", everything is alive, has consciousness, and is sentient to some degree, even inanimate objects. In other words, all is "animated". But, this is still true in many worldviews, up to and including that of Shintoism, an ancient set of spiritual beliefs and practices of which a large portion of the Japanese population, essentially, still adhere to.

Animism is defined as the worldview in which "natural physical entities - including animals, plants, and often even inanimate objects or phenomena - possess a spiritual essence". I suppose, how one defines "spiritual essence" is where a lot of people get tripped up.

But, to the child, the primitive, the artist, the naturalist, the mystic, and even a quantum physicist or two, that quality we call "life" permeates existence... either it's everywhere... or nowhere.

When in doubt, listen to an eloquent rock.

More Ancient-Future Artifacts... Bismuth Crystals

My friend, Bob, sent me strolling the other day, over to a Reality Carnival: Cliff Pickover's amazing, and constantly updated compendium of strange, mathematical-phenomena links; and I hit pay dirt almost immediately... and, discovered more trinkets to add to my Ancient-Future artifact collection.

Bismuth crystals - who knew?

Resembling ancient Meso-American stepped pyramids, or examples of  fossilized organic circuitry (and, I've been known to generate one or two) these tiny beauties are generated from the chemical element, bismuth... one of the first 10 metals to be discovered - known since ancient times - and the most diamagnetic of them all.

It's also an ingredient in Pepto-Bismol!

Apparently, bismuth crystals are rarely found in nature, but, like the ones pictured, they are grown in labs, or (and, this is the exciting part) can be grown at home on a household stove! (Links are provided at the end of the post.)*

Obviously, the possibilities are not lost on jewelry designers, and the results are items to be coveted.  For some examples, here's a steam-punk pendant by Heather Jordan, and here's Element83's Art-fire selection to drool over.



            


Above, to your left, is a Flickr shot by Sal Tation, but, speaking of drooling, the second photo above is a close-up shot of this article for sale in a UK Etsy shop. I guess money can by happiness, after all!


Some breathtaking close-ups of bismuth can be found at Paul's Lab.

*  Warning: Bismuth does have a degree of toxicity, though generally only with high exposure. According to Wiki: 

"Scientific literature concurs that bismuth and most of its compounds are less toxic compared to other heavy metals (lead, antimony, etc.) and that it is not bioaccumulative. They have low solubilities in the blood, are easily removed with urine, and showed no carcinogenic, mutagenic or teratogenic effects in long-term tests on animals (up to 2 years). Its biological half-life for whole-body retention is 5 days but it can remain in the kidney for years in patients treated with bismuth compounds."
