#31daysofgraves #13 Skeleton
The monument for Elizabeth Benson, obit 1710, in St Leonard, Shoreditch. Carved by Francis Bird, it shows two gleeful skeletons holding a shroud, vigorously ripping apart the tree of life.

It looks more like gypsum (selenite)

Only in Brighton are there ‘real gemstone’ heart vending machines … #urbangeology #brighton
A photo of a cylinder-shaped vending machine on a street which sells heart-shaped polished stones made from agate, jaspers, lapis lazuli etc. A close up of the vending machine merchandise described in the previous image. Heart shaped polished stones in shades of red, blue, green etc.

I do have a marble arse and I’m very proud of it. Thoroughly recommended.

That’s cheap but these stones are not worth much. Only buy it if you like it
pavementgeology.bsky.social
There are plenty of better examples out there! Save your money and wait to find one you like

Huge congratulations, Brenna! Well done! X

There's something about the subtle abstraction in Rose Ferraby's landscapes that always draws me in. I have a similar response to Paul Nash's work on the same subject almost a century earlier.

Tomorrow! My final #urbangeology walk for this year - And it looks like it’s going to be a sunny day! All info in the post below.

My final #urbangeology walk for this year will take place on 4 October. Reservations and more information on #LondonWalks website at www.walks.com/our-walks/th.... Hope to see you there, this is my favourite walk!
Poster for the walk. The text reads ‘discover fossils, stone and astronomy in the city of London! The Monument, the Moon and Malta: urban geology on Eastcheap. Meet at 14.30, Monument Station, Fish Street Hill.’ The background image shows a photo of the Malta War Memorial, a block of squared stone with attached black plaques with maps of the Mediterranean and a description of the siege of Malta during World War II.

And one of my favourite things is when stone is carved into the form of a book! Thanks for sharing!

A library of stone in Alex Wenham's studio. I really can't explain how much I love stone - and the people who work it.

Thanks for sharing this - we’ve found azurite pigment in the Neolithic, but this pushes it right back - a nevertheless rare use. The really lost pigments are those created from dyes which would have faded away long ago.

Really interesting article (and fab video) - rewrites the history of colour pigments and use and raises the question of what other colour pigments may have been used but not preserved? @pavementgeology.bsky.social

Europe's oldest blue pigment

Dating back ~13,000 years, it questions the long-held belief that Palaeolithic artists only used red or black and indicates a more vibrant Ice Age world than previously imagined
