A Secret Egyptian Code Hiding in Plain Sight?

Thirty-three hundred years ago, an obelisk was carved in ancient Egypt. It stood at the entrance of the Luxor temple as part of a pair.

Almost two hundred years ago, the obelisk was given to France by Egypt’s ruler. It stands at the Place de la Concorde in Paris, thousands of miles from its sibling in Egypt.

Two centuries of students and tourists and philosophers and photographers and scholars gazing at the obelisk, reading the intricately carved hieroglyphs.

Hieroglyphs were traditionally written in columns reading downward. But there are also left and right directional markers, marking the beginning of a sentence, often indicated by which direction a human or animal figure is facing.

As you can see, the placement of different symbols allows them to combine with others, both vertically and horizontally, to create different words or concepts.

And whomever did the inscriptions on the obelisk used the multidirectionality of the language to conceal messages in plain sight.

Even after centuries of study, it took a keen eye and some lucky conditions for Egyptologist Jean-Guillaume Olette-Pelletier to uncover the hidden messages.

You see, the obelisk was surrounded by scaffolding as part of its renovations, and this allowed Olette-Pelletier to get up close to the highest point of the obelisk and observe the inscriptions rarely seen by casual observers.

The hidden messages required him to read the hieroglyphs horizontally rather than vertically, and at a particular angle as well. This three-dimensional study of the inscriptions, known as crypto-hieroglyphs, allowed the creator to conceal messages that didn’t simply sing the praises of Pharaoh Ramses II, but actually point to his rulership as divine right, claiming his power came directly from the gods themselves.

It was propaganda, intended to reinforce the pharaoh’s status in the eyes of the elites of Egypt, cloaked in messages for the common people. (One of the messages, for instance, could only be seen by those arriving by boat, a privilege available only to the elite.)

For example, from an article in EuroWeekly News:

“People had not noticed that under [one of the drawings] of the god Amun, there is an offering table. This allows us to discover a sentence where no element is missing: an offering that the king gives to the god Amun,” Olette-Pelletier told BFMTV. Combinations of the newly identified inscriptions produce additional meanings in what’s called three-dimensional cryptography. In total, the Egyptologist identified seven encrypted messages across the obelisk’s various facades. He explained that the enigmatic text can only be understood by walking around the monument.

Imagine the creator of the obelisk, carving with specific angles and readers in mind, an iconic gift to the pharaoh… only for the code to be cracked thousands of miles away, thousands of years in the future, by a different kind of elite.

The puzzly kind.

That’s amazing.

Optical Illusions Made of Wood!

Learning about the science behind optical illusions has been one of my favorite parts of this job. More and more, scientists are figuring out WHY optical illusions work on us, utilizing combinations of color, shadow, perspective, and how we process information to create impossible images, illusions of movement, and visual wonders to challenge how we interpret the world.

And I love seeing how people have responded by pushing the boundaries of what we can do with optical illusions. Earlier this year, I wrote about the glitch quilt, a fascinating and eye-wobbling work of brain-melting color play and meticulous execution.

In a world increasingly reliant on computer assistance and push-button AI-fueled shortcuts, there’s something both comforting and immensely charming about glitch quilts being handmade.

So it should come as no surprise to you, fellow puzzler, that I was overjoyed to discover another example of handmade optical illusion crafting… this time, made of wood.

This is the end grain optical illusion cutting board. It appears to bend and swirl and warp as you stare at it, despite being made of straight lines and alternating colors.

Although I discovered it through Obsessed Woodworking, this particular piece is the handiwork of Ryan Hawkins, who has a woodworking YouTube channel where he detailed the elaborate step-by-step process involved in creating this sturdy perspective-twisting delight:

Ryan, to his credit, pointed to another woodworking content creator who supplied the design plans for the cutting board: mtmwood.

mtmwood has numerous examples of handcrafted visual tricky, employing tessellations and tricks of perspective to fool the eye into following intricately laid patterns, and my favorite is easily one that they call the butterfly board:

Employing a similar technique to the optical illusion cutting board, but managing to shape four twisting patterns, is truly impressive and a testament to the hard work, skill, and technique required to bring these stunning pieces to life.

And, as you might expect, this sent me down a YouTube rabbit hole looking for other wooden optical illusions, and there are plenty to choose from.

This is a nicely executed attempt at showing dimension and depth to get us started.

Whereas this one walks us through all the stages of preparing to take a familiar optical illusion from a drawing to a three-dimension form:

I confess, I watched this next one three times in a row, trying to spot the seams:

I could go on and on, but honestly, instead of closing out on the illusions, I’d like to end this celebration of creativity and artisanship with a simple photo showing the preparation and painstaking work it takes to bring these pieces to life.

This is the optical illusion cutting board in its embryonic stage, a lineup of different pieces and thicknesses of wood. All marked and cut with precision, waiting for the next step in assembly. I stare at this picture, and consider every mark, every cut, every spin of the table saw’s blade as the creator runs piece after piece after piece through those whirling metal teeth, each of them perfect and crisp.

It’s a remarkable thing to ponder, and a joy to watch in both progress and in final realization. I’m glad I could share that with you today.

Happy puzzling, everyone!

A Puzzle Party for Reproductive Justice!

There’s a long history of activism and advocacy through puzzles. Women of LettersGrids for GoodQueer Qrosswords, These Puzzles Fund Abortion… these are just a few prominent examples of constructors and creators donating their time and puzzly efforts to benefit the world at large.

And the wonderful team at Frontera Fund are using puzzles to help raise awareness next Thursday, May 8th with their Puzzle Party event!

Cactus Valley Art in Harlingen, Texas, will be hosting the event.

There will be puzzles, community support, and discussions of the modern abortion access landscape and the challenges involved in ensuring that women and those assigned-female-at-birth have the support and resources they need.

This is a wonderful way to help get the word out. I hope that you’ll participate in the event, either by attending in person, by following through social media, or by donating to the cause!


I’d also like to take the opportunity to shout out These Puzzles Fund Abortion 5 . This year marks the fifth edition of the project, collecting 23 puzzles centered around social and reproductive justice themes, all for a minimum donation of $25.

If you donate $50 or more, you will also receive the puzzle packs for the previous four years of TPFA.

Whether you support Frontera Fund or the five important charities involved in These Puzzles Fund Abortion, I thank you for your time, your donations, and your participation in helping protect and provide healthcare for others.

Together, puzzlers can change the world.
