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. 🤩

@cosmopoet.bsky.social , maybe of your interest (even if Latin) ⬇️

Wonderful days in Cambridge with Visualizing the Unknown @huygensknaw.bsky.social and Visualizing Science @bhmpi.bsky.social teams to explore collections and exchange with scholars working on Visual Culture and Natural History. @Fitzwilliammuseum @hpscambridge.bsky.social @whipplemuseum.bsky.social

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

A four-year-long collaboration with EIDA-Editing and analysing hIstorical astronomical Diagrams with Artificial intelligence reaches a crucial milestone in Paris next week: eida.hypotheses.org/a-global-his... 🤩✨ @obs-paris-psl.bsky.social #histsci #diagrams #manuscripts

Thrilled to have COSMOPOET represented as part of the celebrations for 30 years of MSCA at UGent yesterday! 🎉✨ Here’s to many more years of curiosity, collaboration, and discovery! 🚀💫 #MSCA30 #MSCA #ResearchLife #UGent

🎉 Happy 30 Years to #MSCA, a programme that has helped researchers explore new frontiers and build independent careers! COSMOPOET will have a stand at the networking event this afternoon — come meet @dulila.bsky.social and join the celebration! event.ugent.be/registration...

#starrywalks in #ghent continue with a chance discovery on Korenlei, a corner I have taken multiple times before. I guess today the light was just right for me to notice this beauty 😍 #armillary #sphere

🧵🧵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':

Random cosmopoetic things from recent weeks

This Thursday, 12 March 2026, Emmylou Haffner and Nadia Podzemskaia organise a truly cool event, across arts and sciences, on the topic of points and lines. COSMOPOET will be present with achromatic lines and cosmological diagrams. The program is available here: www.item.ens.fr/points-et-li...

This week Cosmopoet is in sunny 🌞 (no joke!) Cambridge and there are clocks all around: some eat time, while others are on a diet ☺️

OIKOS Course Byzantium in the Global Middle Ages at UGent 📅 2–3 February 2026📍Ghent University The biennial OIKOS course on Byzantine Culture brought together ReMA and PhD students from Belgium and the Netherlands for an intensive exploration of the theme of Byzantium in the Global Middle Ages.

Happily listening to Arpine Asryan about the introduction of #sundials to Armenia in the seventh century 🥰☀️🕒

The final #poem for this week is a poem cast against a #cosmic background in the movie Interstellar: "Do not go gentle into that good night" by Dylan Thomas. I thank my colleague Yiming Liang for this suggestion! www.youtube.com/watch?v=3_np...

And a second post today, this time for the project records: on 2 and 3 February 2026, the OIKOS #Byzantium in the Global Middle Ages course will take place and within it, a very exciting research mixer, a result of COSMOPOET's ongoing collaboration with #HPIMS: www.rug.nl/research/res...

The second #poem this week was suggested by Matthieu Husson, a historian of medieval astronomy. This is "Remember", by Joy Harjo: poets.org/poem/remembe...

🧵After learning about the idea behind Cosmopoet, friends and colleagues have started sending me poems that fit the theme and that they love. This week I want to share them here, one at a time. The first suggestion is by Eleonora Cattafi, a poet herself (research.flw.ugent.be/nl/eleonora....):

The call for the 2026 Training Week: Global History of Astronomy on Primary Sources – A Focus on Cosmology, Physics and Astrology is now open! eida.hypotheses.org/seminars-2/2... June 8-12 2026 Bibliothèque nationale de France, Observatoire de Paris Deadline: 30/01/26 #historyofastralsciences

I took the wrong exit and stumbled upon the impressive constellation ceiling leading towards Galerie Ravenstein ✨✨✨💫💫💫🌌🌌🌌 #starwalks

New volume of Methodos Vol. 25 (2025) journals.openedition.org/methodos/10599 @openedition.bsky.social Les mathématiques médiévales dans le monde latin @medphiljournals.bsky.social

A new installment in the Ghent #starwalks (and I don't mean the recent sightings of Nicolas Cage shooting a movie on the Graslei) comes from a private residence, a sun ☀️ and moon 🌙 house that is only visible after dark 🌑

An example of impact: first you speak about lunar phases #diagrams in 14th C #Byzantine #manuscripts, then you find them recreated in the doctoral students' office 🤩🙏🏻🌑🌒🌓🌔🌕🌖🌗🌘

I've been documenting #starwalks in Ghent, but here is a nice find from Saint-Germain-en-Laye as I was walking with @florence-somer.bsky.social : a bell tower, a clock and the #zodiac 🐏⚖️🦀🐐✨✨ The church of Saint Germain, 1827.

This Friday, 21 November, COSMOPOET will present at the lunch seminar of Henri Pirenne Institute for Medieval Studies: www.ugent.be/pirenne/en/n... This is an in-person event. All are welcome!

In November, COSMOPOET invites you to: 1) on 13 Nov, a History of Science, History of Text seminar day on Diagrams and Illustrations (sphere.cnrs.fr/en/event/sem...), both in Paris and on Zoom; and 2) an in-person double HPIMS lunch lecture session in Gent on 21 Nov www.ugent.be/pirenne/en/n... ✨🌌📖✨

Too tired to make any meaningful posts right now, just wanted to say a huge Thank you! to everyone involved!! I am so grateful, so impressed by everyone's ideas, kindness and support and so sorry it all went so quickly! Good night to all cosmopoets!!

Day 2: almost set up

Not many photos from today, except for the inspiring Wim Verbaal and the astonishing Liber Floridus. Main take away: we really need to rethink what "didactic" means in different contexts, but also when "numbers" encode meter & poems act as instances of creation of worlds - fictional but also real.

More walking, more "cosmic" images of Ghent 👩🏻‍🚀🎈🎈

My starry walks around Ghent continue. 💫💫This time with the discovery of this celestial globe (no stars, just celestial circles but still) - part of the sculptural composition of the rococo pulpit in St Bavo's cathedral designed by Laurent Delvaux. 🤩🌐✨🌌

🧵🧵In the very first instalment of this guest author and fellow stargazer 🤩💫and skywalker 🌌👣series, it is my pleasure to introduce Stamatina Mastorakou (@smasto.bsky.social), the October Cosmopoet! Here's what she had to share about her chosen poem:

🧵🧵As much as I find the research I am doing for this project fascinating and fun for me to do, I have been thinking that I am missing the collaborative community-building and fostering element that is usually not at the core of individual postdoc projects.
