Every five years Byzantinists of all corners of the world gather to discuss all things Byzantine, and next week in Vienna will be no exception. If the history of science is your passion, come hear us on Friday morning: www.icbs2026.org/program/ @aieb-byzantium.bsky.social #ICBS2026 #histsci

And here it is, and our weird eclipse shadows

Everyone looking and waiting, including the Book Tower!! 📚📚📚

8 minutes until we reach the maximum of 90% occultation visible here in Ghent

And an alternative view

Armand Pien Observatory has turned all of its telescopes to the celestial spectacle, including this history beauty

Let's practice some Dutch and learn the mechanics behind a solar eclipse ☀️🌑🌍

I am in heaven, eclipse observation has started at the terrace of the Armand Pien observatory at Ghent!

#starwalks the summer edition ✨✨✨: observation in the Observatory in Kamen bryag and a projection in the planetarium in Toplocentrala, Sofia. The first one was the true highlight: bnrnews.bg/en/post/9022...

COSMOPOET's #starwalks continue with suggestions by those who attended the first Ghent StarWalk in June. The first one comes from Grigory Vorobyev: Built in 1980, this landmark features a white terracotta relief representing "the cosmic marriage of the past and future". #MSCA ✨🚶‍♀️🤩

Alfonsine Astronomy, vol. 3: Computational Practices is now out—and fully open access! 🎉 "Unfolding more than two centuries of late mediaeval astronomers’ computational practices, this collective volume explores new venues in the history of astronomy." @brepols.net www.brepols.net/products/IS-...

And just to continue the theme of marine creatures following the Écrevisse post from Paris: the Crab make an appearance at the Belgian coast #starwalk 💫✨💫✨🦀🦀🦀

And the last one for today: accidental #starwalk in Mechelen 💫✨💫 Sundials, Moons and the Spherical universe - not too bad for a leisurely Sunday exploration.

Accidental #starwalk in Paris: how many times have you been looking for the Crab but instead found the Écrevisse ? ✨💫✨💫🤩 This is one of two we have found. Can you guess where the second one is?

Still not ready with the Ghent #Starwalk recap hence only posting accidental #starwarks: Antwerp 💫✨🤩🤩

Things have been so busy I forgot to post here the programme for the #CoSciLit 2026 where Cosmopoet will present tomorrow: coscilit2026.ugent.be/en/programme

On the occasion of the annual day of the Belgian Byzantinists, I also managed to do a second mini #starwalk in Leuven and so I would like to add to Verbiest's globe, this art installation, thanks to which it is possible to step right in the beginning of everything ✨✨💫💫

Starting on Monday we will be teaching the history of the astral sciences on a global scale with the historical sources themselves: manuscripts, prints, globes, astrolabes - thanks to @labnf.bsky.social and @obs-paris-psl.bsky.social for hosting us!! ✨✨ eida.hypotheses.org/seminars-2/2... #histsci

This was long in the making, mostly as I walked around Ghent and thought about it, and also in this space. We will give it a try tomorrow 🤩 💫✨ More updates soon! Including the map and the zine in digital form. Of course some of it will remain ephemeral. As it should be.

And a #starwalk in Leuven revealed the 1:1 replica of the 17th C Kangxi-Verbiest Star Globe: www.atlasobscura.com/places/kangx... 🤩💫✨⭐

Despite the meltdown of the trains in Belgium, the #OIKOS Crash Course in #Greek #Palaeography hosted by @unileiden.bsky.social was a true and rare delight: an armillary sphere: a 9C Handy Tables and a very happy @dulila.bsky.social 😍🤩✨✨💫💫 #starwalks

Accidental #starwalk finds in Brugge: a gnomon (www.patrimoine-horloge.fr/ha-bruges.html) and Simon Stevin's "beads" (en.wikipedia.org/wiki/Simon_S...) ✨🤩💫

Next week in Leiden: OIKOS Crash Course in Greek Palaeography 2026 www.universiteitleiden.nl/en/events/20... I am super excited that the display session I am responsible for will focus on the history of science with Byzantine copies of Euclid, Kleomedes and, of course, Ptolemy🤩🤓✍️📖

I hope I get to do a little recap of the Multigraphic Written Artefacts second workshop soon, but for now an entry into my #starwalks from a beloved Butte aux Cailles where the entrance of metro Corvisart sports four terrestrial spheres with a zodiac, two at each gate 🤩🤩✨✨💫💫

📣The collaboration between @obs-paris-psl.bsky.social and @csmc-hamburg.bsky.social continues with the second workshop dedicated to the spatio-temporal profile of multigraphic written artefacts: 18–19 May 2026, Paris, at Observatoire de Paris and online. 🤩

Dr Kristen Lippincott gave a fascinating lecture in the Warburg recently, discussing the representation of the constellations and figures on a celestial globe, in artworks from c15th Italy kept in the Biblioteca Nazionale Centrale.

I 💜 @astra-mpiwg.bsky.social "10 Questions for the Historian of Science". To the point and utterly enjoyable 😊 Here is the latest installment with Luís Campos Ribeiro (another EIDA contributor✨🌐✍🏻 & historian of astrology): www.mpiwg-berlin.mpg.de/feature-stor...

A planetary diagram by 10-yo Leonora Carrington positioning the planet Starvinsky, a cosmological diagram that came later, a windrose without directional labels, and the world as an egg with celestial circles inscribed. @Musée du Luxembourg #cosmopoetinlove #diagrams personal #cosmologies

This week dedicated to #diagrams is now over, but the work continues towards the publication of our results and the next phase in the life of the #EIDA community. Huge thanks to @obs-paris-psl.bsky.social for hosting us and for sharing it's beautiful secrets with us! #msca #histsci
