Divna Manolova is our Staff Member of the Month! She recently started her project, funded by the Marie Skłodowska-Curie fellowship, which explores the role of versification in teaching astronomy in Byzantium. We chatted about her new project, AI spotting diagrams in historical sources, the flat Earth theory, her favourite chocolate shop, and her dance classes. Welcome, Divna!
Hi, Divna! You recently started you new position in our section as a Marie-Curie fellow, welcome! Could you explain the focus of your project?
Hello, Olivier, and thank you! My project’s acronym is COSMOPOET which stands for the study of the role poetry and versification more generally (might have) played in the teaching of the astral sciences in Byzantium. My focus falls specifically on didactic poetry used within the framework of teaching cosmology and introductory astronomy. I study the Phaenomena by Aratus of Soli (d. before 239 BCE) and the way it was read, commented and studied as part of, what I argue, is a ‘new’ curriculum forged by thirteenth-century Byzantine scholars. I contrast the reading of the Phaenomena with the reading of prose texts such as The Heavens by Cleomedes (first century CE) and ask what the difference was between explaining the structure of the universe in hexameters and reading about it in prose. Those interested in the project’s activities could follow us on Bluesky.

You’re also a member of EIDA (Editing and analyzing hIstorical astronomical Diagrams with Artificial I-intelligence), an interdisciplinary project that utilizes computational resources to retrieve and analyze diagrams in manuscripts. Could you briefly explain what a diagram is, describe your role in this project, and share your perspective on the usefulness of AI for our field?
Yes, of course! I became a member of EIDA in 2023 when I moved to Paris for my previous postdoc as a MSCA Paris Region fellow. At the time, my work was also about the teaching of the astral sciences in Byzantium but the focus was very much on the use of diagrams in instructional works. My main corpus consisted of the 84+ extant manuscripts preserving Cleomedes’ treatise The Heavens and on the diagrams most of them contain. At present, I continue thinking along the same lines both within COSMOPOET and as EIDA’s scientific collaborator and me and my colleagues keep asking the same question you asked, Olivier, namely “what is a diagram?”. I am sure it does not come as a surprise if I say that many of us at EIDA embrace different definitions even though we restrict our corpus to astronomical diagrams preserved in historical sources (mostly manuscripts but also prints in the case of the Chinese material). In terms of their design they all employ the geometrical idiom, that is they employ lines and circles, arcs of circles, and points, and they feature a variety of labels in a variety of scripts written in all kinds of colours and directions. These are also the elements that we have focused on in developing and in training computer vision tools that can facilitate the creation of natively digital scholarly editions of diagrams. EIDA is a Digital Humanities, and more specifically a Computer Vision project, so the challenge but also the beauty of our work is the conversation between historians and computer vision researchers (a fun example of this collaboration is this outreach talk my colleague Jade Norindr and I did for Astronomy on Tap Paris last year). In this sense, the working definitions of a diagram I employ change when I am thinking about the training of one of EIDA’s computer vision algorithms and when I wear my historian’s hat and think of the late Byzantine scholars and scribes and what they defined as diagrammatic. Finally, when thinking of what diagrams are and aren’t I find it useful to ask what the difference is between telling something and showing something. In fact, diagrams can both show and tell and on top of that, they can show multiple things at the same time, for instance a diagram can simultaneously explain the lunar phases and how a lunar eclipse occurs. A narrative can only do this in a linear fashion – first explain one phenomenon, then the other. A diagram, however, can offer a synoptic view and explain both at the same time.
As to your question about the usefulness of AI in our field: based on my experience so far, I think that the answer depends, first, on the research questions one wants to pursue and second, on the amount of data one has. If a researcher’s corpus is relatively small, then probably creating an AI tool to study it is not necessary, whereas truly large corpora become more manageable thanks to AI.
Given your work in teaching ancient science, particularly ancient astronomy, do you have an opinion on the recent flat Earth theory and its implications for science education today?
Well, the myth I have always been quick to debunk during museum tours is rather the incredibly persistent popular belief that in the Middle Ages people believed that the Earth was flat. The European Middle Ages embraced the doctrine of the sphericity of the Earth (and the universe) as a mainstream scientific explanation even though alternative cosmological models were also attested (e.g., an egg-shaped Earth or, indeed, a rectangular and flat Earth). Nevertheless, all medieval European astronomy is based on an assumption that a spherical earth is positioned in the centre of a spherical universe and hence the rules of spherical geometry apply. Believing that the Earth is flat or believing that there is no proof that it is not in our contemporary world this raises questions concerning attitudes towards the notions of scientific truth and expertise and even identity and community construction. As educators what we could do in any sphere of knowledge is to help train the mind to question, to assess, to doubt, to examine, to argue, to discuss. Thinking and understanding are not a given. We need to insist and to persist in insisting that those skills require formation and continuous exercising irrespective of whether the subject we teach is within the arts, the humanities or the sciences.

Having recently arrived in Ghent, could you share the most unexpected cultural shock you have experienced and what has made you feel most at home?
I think what I am having most fun with is the difference between what I would consider close and far and what the people of Ghent would characterise as such. Some people are shocked when I tell them it takes me only 25 minutes to walk to work!
As with everything excellent in life, to me at least, what makes me feel at home are people and their kindness – whether it is the chocolatrice near my place who knows me already and indulges me by explaining the process behind the creation of her pralines, or the Bulgarian bakery around the corner where I can have the rare pleasure of speaking my native language, my tango school where I do not have to talk at all, or my friends who took care of me when I tore ligaments in January, Ghent has quickly become my home away from home and I hope it gets even better with spring approaching!
What do you enjoy doing when you don’t have your head in the clouds?
When is that? 😊 Mostly I read books, listen to podcasts, and travel. Monday is a tango night and recently I have joined a crochet and knitting group that meets in a café once a month. It is not easy but it is a way to meet people and to do something that does not involve looking at a screen all the time. I am also a sundial and a labyrinth enthusiast so the rectangular labyrinth in Ghent’s Town Hall is on my get-to-know-Ghent to-do list!
