Page in the bulletin from the Scientific Instrument Society showing the article "Gerard Turner Memorial Lecture. Back to the Future: New Approaches to the Astrolabe" by Stephen Johnston. A photograph of the front and reverse of an astrolabe is included in the upper right corner of the article.
I recently joined the Scientific Instrument Society and they sent me one of their recent bulletins as a welcoming gift. I am so pleased to open it and to see @stephenaj.bsky.social's article on Astrolabes on the first page ❤️ #EarlyModern #MedievalSky #HistSci #HistTech #HisSTM 🗃️
