Welcome!
I work with the geoarchaeology of old stone: quarries, monuments, rock art. And I try to figure out about their weathering, and conservation using traditional crafts. I also burn lime the traditional way. Many of my domestic services are managed through FABRICA, a registered Norwegian company established with good partners. On this website I publish articles on geology and cultural heritage. I don't use AI for text or images. For the joy of old stone! Per Storemyr

The Côa Late Palaeolithic rock art in Portugal. A brief comparison with petroglyphs of similar age in Egypt
On working with Late Palaeolithic rock art in Upper Egypt several years ago, sometimes we used to compare the naturalistic style of newly found petroglyphs with photos of those in the Côa Valley (NE Portugal). This was because the large Côa site has open air petroglyphs, whereas most other Late Palaeolithic rock art sites feature cave paintings. But I was never able to visit the Côa site to see for myself how the petroglyphs compare. Until now. On a road trip this summer we got a glimpse of the Côa images, at the Penascosa site. This brief article shows many similarities between the rock art in Côa and Upper Egypt, but also a harsh difference: Whereas Côa is a well-managed UNESCO World Heritage Site, the rock art in Egypt is under immense risk of destruction by modern mining.
