Pompeii vs. Herculaneum

Italy’s celebrated archaeological site of Pompeii is compared and contrasted with nearby Herculaneum in terms of art, architecture, visitor experience, and (of course) geology.

Friday fold: Villa Romana di Casale

Okay, I’ll admit this is a bit of a stretch, but here’s your Friday fold: The mosaic-covered floor of this long hallway in the Villa Romana di Casale in central Sicily shows profound warping. The middle shadowed area sags downward by at least a meter, maybe more. It’s not a geological material that’s been deformed, but an architectural element instead. Still: the principle of original horizontality applies to floors as …

Friday folds: the Roman Forum

When in Rome, do Friday folds as the Romans do? Here are some images from my brief, sweltering visit to the Roman Forum(s) this past summer. The whole region is a jumblepile of ancient ruins in a thousand styles. Almost nothing is labeled. It looks like this: This particular building held up a bit better, and its lovely columns sported some folded marbles: Close-up shots to show the folding internal …

Monday Geology Picture: Nimrud Statue at the British Museum

I was very upset to learn that a few days ago ISIS looted and bulldozed the ancient Assyrian city of Nimrud in Iraq. This war crime is a terrible tragedy, and I hope that not all of the city’s treasures were destroyed. Fortunately, many artefacts from Nimrud are preserved in various museums around the world. In a way, that is bittersweet. I really wish that artefacts from Nimrud could primarily …

Monday Geology Picture: One More Egyptian Artefact from the British Museum

Over the past few weeks, I’ve been sharing pictures of ancient Egyptian artefacts from the British Museum for my “Monday Geology Picture” posts. Here’s one last picture from the British Museum: a rock slab engraved with ancient Egyptian figures and writing. I didn’t take a picture of the informational sign, so let me know if you recognize the artefact. I think that this picture shows part of a larger artefact. Whatever the artefact, …

Monday Geology Picture: A Granodiorite Horus

For this week’s “Monday Geology Picture” I thought that I would share a couple more pictures that I took during my recent visit to The British Museum. When I was in one of the exhibits with ancient Egyptian artefacts, I was struck by a beautiful dark-colored Horus statue with a light-colored vein running through it. According to the museum sign, the statue was carved out of granodiorite. The vein is probably …

Monday Geology Picture: Ancient Egyptian Stone Jars

For this week’s “Monday Geology Picture” I thought that I would share another picture that I took during my recent visit to The British Museum. This week’s picture shows two beautiful ancient Egyptian stone jars. The jar on the left is made out of limestone breccia while the jar on the right is made out of andesite porphyry. Here’s the museum sign about the two jars:

Monday Geology Picture: Written in Stone

A few weeks ago I flew from the USA back to my home base of Cape Town, South Africa. During the journey, I had a long layover in London, so I left the airport for awhile and did some sightseeing. Among other touring, I spent several hours at The British Museum, where I saw many interesting artefacts. The most fascinating and awe-inspiring artefact that I saw was a slab of …

Thursday Geology Picture: Sandstone Statues in the Petra Siq

Geology picture-a-day week continues here at Georneys. Today’s geology picture comes from one of my favorite places on Earth: Petra, Jordan. Petra is an ancient Nabatean city nestled in a broad valley that is protected by steep sandstone terrain. Petra is accessed by the Siq, a narrow canyon through the sandstone. The geology of the Siq is impressive enough: the walls of the canyon reveal beautiful, red rose colored sandstone …
