Ptolemaic Engraving


ancient stone d20 alpha side upSo nearly 2 years ago one of my customers (I do apologies, but I can’t remember her name for the life of me, and the message has been long since buried) put me in touch with the Metropolitan Museum of Art about making a modern interpretation of the worlds oldest twenty sided die.

Reverend Chauncey Murch d20 courtesy of Metropolitan Museum of Art This die was originally collected by Reverend Chauncey Murch, who found the piece while serving as a Missionary in Egypt between 1883 and 1906. It was originally crafted some time during the 2nd or 3rd century B.C. putting it at towards the end of the Ptolemaic Period. Upon Reverend Murch’s death the die was purchase by the Metropolitan Museum of Art in 1910.

Originally the die was crafted from Serpentine which is a semi precious stone that ranges in tone from brown to green and is a source of both magnesium and asbestos. Serpentine gets its name from the green scaly appearance in serpentine’s natural form. Serpentine is used extensively in gems and ornamental work. When polished it has contains cloudy patches interspersed among clear regions.

So instead this weekend I noticed Fluffy had cut up a ton of architectural grade soap stone blanks for something else he was working on, and for some reason it sparked a memory of this old project. So, Fluffy’s blanks went missing and I fired up the CNC’s then I set about figuring out what those funny symbols were, which was something that had been giving me fits off and on for the past 2 years and was one of the reasons this project languished on the back burner for so long.

You see the MMA has the symbols listed as the first 20 letters of the Greek alphabet. And while that is mostly true, it’s not quite right. As you can see in the first photo on this page diamond-shaped symbol that is NOT in the Greek alphabet. And if you look in the photo below of the die in the walnut box you will see there is a ‘C’ shaped letter that is also NOT part of the Greek alphabet. After a bit of searching, the ‘C’ shaped letter turned out to be Coptic in origin, and was the Coptic equivalent of the Greek letter Sigma. But for the life of me I could not find a letter in either Coptic or Greek that was the same shape as the diamond-shaped letter in the first photo. The closest thing I could come up with was Sampi which is the outdated Greek symbol for 900. But it just didn’t look right, and the MMA says that it should be one of the first 20 letters of the Greek alphabet. But it’s not a Coptic nor Greek letter.

The only remaining letter in the first 20 letters of the Greek or Coptic alphabets that remained unaccounted for was the letter Alpha, and it just didn’t fit. And then I stumbled across, this photo on this page. Then after a few more beers and even more poking though the recess of the internet, I finally figured out that the mystery symbol turned out to be a stylized geometric representation of the Coptic Alpha.

But why would the MMA say these were the first 20 letter in the Greek Alphabet, when there were 2 symbols that were most definitely Coptic in origin? Well after a bit more research I discovered the answer to that question lies in the time period in which this die was crafted. Coptic was the latest form of the Ancient Egyptian language, however during the 2nd and 3rd century B.C. the Egyptians began transitioning to the Greek system thanks to a small encounter with Alexander the Great. Though the details of that encounter are a bit out of the scope of this post, it’s still pretty neat to see some of the greatest events in Antiquity become apparent in the symbols on the world’s oldest d20.

While the original die was most likely not used for gaming, but instead created as an exercise in contemporary geometry. After all the platonic solids were first studied by the Ancient Greeks around 360 B.C. Most notably by Plato, for whom they are named, and Theaetetus who was the first to describe them mathematically.

The Artisan Dice version of this particular dice needed to be a gaming piece. To that end, you’ll notice that the letters on our version all face the same direction as they would on our normal N+1 style d20s. I’ve also set the font in a more modern serif style of the Greek/Coptic Alphabet. Where as the original was set in an overtly geometric type.

That left only one small problem. What do we call this thing? “The modern emulation of the world’s oldest twenty sided die”, is a bit of a mouth full to say the least. So after going back and forth with the minions, some of whom were still upset about some missing soap stone blanks, it was decided that the die should be called a Ptolemaic d20, to pay tribute to the era in which the design was originally crafted.

    These dice look fantastic.
    They are ideal for a product that we have just bought out. You can see it here:!moon-board-/c1n03
    I am wondering if we can work something out?
    Can you tell me how much these would cost? We would be buying them in batches of 10.
    A larger bulk purchase would not work, as we only sell a few of these items, they are pretty much top end.
    However, if you are interested – we could put a link to you on the site.
