🧵🧵Spring brought more daylight and Cosmopoet's second guest author, fellow stargazer 🤩💫and skywalker 🌌👣: Davide Massimo (@davidemax.bsky.social) is this month's Cosmopoet, and he brings us an example of an epigram concerned with the 'image of the sky':
There will definitely be spare Planicelia… for whoever wants to experience the super efficient methods of domification and direction made possible by the Planicelium.
This is a wonderful moment of preparation of the upcoming EIDA workshop. I am most grateful for this support, and look very much forward to see the instruments in action! (Even if, as a consequence, we figure out that we got it all wrong with our reconstruction of this arcane instrument…)
It is a Saturday and what better activity than building planicelia together with @sgessner.bsky.social and Florence Somer in preparation for Celestial Scripts on Monday!
Thank you Veronica for presenting us these fascinating vistas from the amazing Tartaglia. Avery relevant author in the context— read by so many all over Europe (including Pedro Nunes, mathematician and royal cosmographer in Portugal).
🎉 Today's the first day of our "Euclid's Elements and Practical Mathematics" workshop in Wuppertal 📖 I'll try to present the speakers, beginning with Philip Beeley ⤵️
Beautiful adventure, many thanks for being persistent and doing much of the heavy lifting! I learned so much from both of you.
Ärgert mich auch. Aber für die NZZ leider nicht überraschend… da kommen sehr regelmässig Stimmen zu Wort, mit Wasser auf die falschen Mühlen. Zum Glück sind viele Leser schlau genug, solche Artikel mit mit Vorsicht zu geniessen.
Yes. The regulating mechanism (verge and foliot) was replaced in most 15th and century clocks. It’s a tragedy for the clock historians as so much of the historical evidence has been destroyed through the ‘modern improvement’ by a pendulum.
I remember this happened to the planetary clocks…
There are a few…
Salle Cassini, with the seventeenth-century brass meridian line on the floor…
Already looking forward to the 2026 edition!

Even more so, to help shape this shared journey: creating spaces for conversations between people and between diagrams from historical manuscripts and prints—in Chinese, Arabic, Persian, Hebrew, Greek, Latin, and various vernacular traditions.
Just wrapped up the 2025 EIDA conference—once again, an incredibly productive and inspiring gathering. Held in the historic building of the Observatoire de Paris, it was a true pleasure to listen to and exchange ideas with so many sharp and generous scholars—both in person and online.
From June 2 to June 6, 2025, the Training Week: A Global History of Astronomy on Primary Sources: New Approaches, New Digital Tools will take place in Paris.
Limited number of scholarships; deadline April 18, 2025.
