One of the wider activities with which the Ordered Universe is engaged is the OxNet access initiative, which seeks to place university learning directly into schools. In the case of the collaboration with Ordered Universe this involves team members bringing the world of medieval science and of the array of disciplines that make up the project to Continue reading
Yesterday, February 9th, was the opening of the 6th Cambridge e-Luminate Festival. Members of the Ordered Universe team were delighted to be asked to give an afternoon of talks, demonstrations and interactive activities as part of the opening events. Seb Falk (Cambridge), Jack Cunningham (Bishop Grosseteste University), Josh Harvey (Oxford), Giles Gasper (Durham), and Alexandra Carr (Multi-Media Sculptor), Continue reading
2018 is set fair to be another busy year for the Ordered Universe team. In addition to submitting our first volume presenting the treatises On the Liberal Arts and On the Generation of Sounds, and the Middle English Seven Liberal Arts, to press, we have a wide range of other events organised. This is just a reminder of those coming up in the first quarter of the year.
The two exhibitions featuring work inspired by the project run over this period. Illuminating Colour, a major exhibition of new work from Cate Watkinson and Colin Rennie at the National Glass Centre, University of Sunderland, drawing on Grosseteste’s treatises On Colour and On the Rainbow runs until March 10th. This is a world-class exhibition – do come and see it in situ. And, if you find yourself in the North-East come along to the Dante Exhibition at Palace Green Library in Durham and see, amongst the other treasures, Alexandra Carr’s sculpture of the nested spheres of the medieval universe, and a film installation as well. Alexandra’s work was produced as part of her Leverhulme Trust funded Artistic Residency at Durham University and Ushaw College focusing on medieval and modern cosmology.
January sees the fifth symposium of the current series, at Pembroke College, University of Oxford. In addition the OxNet course at Southmoor Academy recruits and commences its 6 week seminar series, to be taught to schoolchildren from across the North-East at the National Glass Centre. This involves Richard Bower – on Cosmology, Brian Tanner – on Physics, Joshua Harvey – on Psychology, Nicola Polloni and Kasia Kosior – on Translation, Cate Watkinson and Colin Rennie – on Creativity, and Giles Gasper and Tim Farrant on History and Religion. All co-ordinated by Kasia Kosior and the wonderful OxNet team.
February features a number of different activities. Tom McLeish and Giles Gasper are speaking on 7th February, on the modern and medieval cosmos, as part of the Dante Lecture series organised by Durham University’s Institute of Medieval and Early Modern Studies (IMEMS). Friday 9th February will see the Ordered Universe at the Cambridge e-Luminate Festival of Light for the second year in a row. We’ll be running a series of talks and then show and tell activities over the afternoon and early evening in the Guildhall in Cambridge. And this alongside Ross Ashton and Karen Monid’s new sound and light show. Keeping up the pace, on the 13th February IMEMS is running a day-long workshop on the Scientific Study of Manuscripts, Brian Tanner and Giles Gasper will be talking on Ordered Universe experience of interpreting medieval thought using science and humanities methodologies and approaches. Finally, Jack Cunningham will deliver a lecture in the Ushaw College series in Durham on his discovery of an 18th century life of Grosseteste. ‘ ‘Saving Robert Grosseteste – Fr Philip Perry’s Lost Biography’ takes place on 22nd February, 18.00-19.15
We wrap up the OxNet seminar course in March, and put all focus on the Ordered Universe conference in April – more on that soon, and look forward to the Ordered Universe/OxNet Easter School in Durham – focused on medieval manuscripts, the British Society for the Philosophy of Science conference, and then into the early summer and our Montreal visit, the Kalamazoo International Medieval Congress….and we’re already half way through the year!
Last week, Thursday 23rd and Friday 24th November, Ordered Universe members were made very welcome at the Centre for Medieval and Early Modern Research, and the Department of History at Swansea University. Continue reading
Joshua Harvey, a DPhil Candidate in the departments of Engineering Science and Experimental Psychology at the University of Oxford brings us a report on his time as a ‘Lost Late’ exhibitor at the Oxford strand of the Being Human Festival 2017.
Last Friday saw 1,500 people of all ages congregating under a fabulous mix of lights, music, research, and dinosaurs. The event, ‘Lost Late’, formed part of the national Being Human festival, hosted by both the Natural History and Pitt Rivers museums in Oxford. From 7pm until late into the evening, visitors could stroll through the two connected museums, which had been utterly transformed into a realm of discovery, from mazes to archaeological dig sites.

A post by Joshua Harvey, D.Phil. student, Department of Engineering Science and Pembroke College, University of Oxford, funded by the Andrew W. Mellon Foundation as part of ‘The Mental and Material Laboratories of Medieval Science’ project, under the aegis of the Ordered Universe.
The latest research article from the Ordered Universe project: “Bow-shaped caustics from conical prisms: a 13th Century account of rainbow formation from Robert Grosseteste’s De iride” is available to read now, open access at the Optical Society of America’s journal Applied Optics. Grosseteste’s treatise De iride [On Rainbows], which may be familiar to long-term followers of the Ordered Universe project, explores theoretical optics, colour theory, and meteorology to give one of the most comprehensive pre-renaissance scientific writings on the rainbow. With this most recent article, we explore his pioneering model of rainbow formation – the first to use refraction (and not just reflection) in medieval Europe. Through an interdisciplinary combination of historical review, geometric optics, and both practical and simulated experiment, we give a thorough overview of the historical significance of the De iride, and look at what lessons we can learn from it today.
This fruitful exploration has not been done before. Although Grosseteste provides a detailed description of what he believes are the geometric underpinnings of a rainbow, he has previously been disregarded in this area. David Lindberg even went so far as to say that ‘his theory of the rainbow could not account for even the most basic phenomena and has remained largely unintelligible to the modern day.’ Well, we thought there might have been more to Grosseteste’s thought than that, being familiar with his mathematical mind and keen curiosity about the natural world. As a research team with a diverse expertise, we together arrived at an interpretation of Grosseteste’s optical mechanism that was intelligible, elegant and, most excitingly, perfectly testable. To our surprise, the caustics – patterns of gathered light – produced by a transparent cone are just as Grosseteste describes.
Remarkably, we have already been contacted by researchers investigating atmospheric optics, who have found some striking correspondences between their own work and our interpretation of Grosseteste’s De iride. Markus and Sarah Selmke’s recent paper, “Artificial circumzenithal and circumhorizontal arcs” published in American Journal of Physics, explores to great depths the kinds of refractive optical interactions between transparent cones, as modelled by glassware filled with water, and incident light. The authors have shown that Parry arcs, a type of halo, are analogous to the caustics produced by shining light through a wine glass of water. Although not as frequently observed as rainbows, Parry arcs are similarly beautiful displays of dispersive colour seen in the heavens, providing certain atmospheric conditions are met. The paper features a combination of practical and mathematical experimentation, similar to our own approach in the Applied Optics paper, and states that “light entering through the top air-water interface and leaving through the lateral cone surface results in an analogy to Parry’s halo”. This is identical to Grosseteste’s geometric scheme, as we interpreted it. Although, to his detractors, his likening of a rainbow to that of light going through a transparent cone might sound crude, or even ridiculous, it appears this simple model does indeed capture the optical principles behind a dispersive atmospheric phenomenon.
Grosseteste was wrong about rainbows. Not long after him, rainbows were correctly understood to be produced by light interacting with near-spherical raindrops, by both Kamal al-Din al-Farisi and Theodoric of Freiburg in the fourteenth century. But Grosseteste was not wrong about the optical qualities of transparent cones, and although the optical scene he describes in De iride does not relate to rainbows, it is analogous to another kind of dispersive optical event seen in the heavens.
Of course, it would be incorrect to claim that Grosseteste had solved the mystery of Parry’s arc back in the thirteenth century. He had probably never seen or heard of one, as they are rare outside the Arctic circles, and it wasn’t until 1820 that William Parry observed and drew one. Was this mere coincidence, could Grosseteste have happened upon an atmospheric optical mechanism by chance? Perhaps. But it is worth bearing in mind that his theory was likely grounded in observation, and formulated to be as parsimonious as possible. I think that rather than chance, it is instead even clearer we are reading the work of someone with a scientific mind, curiosity about nature, and a belief in a profoundly ordered universe.

Last week, the Ordered Universe enjoyed a prominent role in OxNet Access Week summer school at Pembroke College, Oxford. Run under the aegis of Dr Peter Claus, the programme is designed to introduce sixth-formers to the realities of university life, study and research (about which more can be read in the previous post). The week’s programme took its title – ‘The World Machine’ – from the project, and placed particular emphasis on the demands of interdisciplinarity. In introducing the summer school as a whole, Giles Gasper urged the 16- and 17-year-olds to ignore the boundaries they were used to, and to shed the fear of appearing stupid or wrong – skills necessary both for interdisciplinary research and the transition from further to higher education.
As such, the separate streams of Humanities, Science and Theology, though operating in parallel, were regularly combined in shared lectures given by members of the Ordered Universe project: Hannah Smithson lecturing on colour perception, Tom McLeish on the role of inspiration in scientific research, Richard Bower on Cosmology, medieval and modern, and Giles Gasper on the Grosseteste’s life, times and scientific output. Working in the college’s chapel, Alexandra Carr produced an arresting light-based multimedia sculpture; an impressive achievement considering her short time frame. This, along with her talks given with Giles Gasper encouraged the students to think about their subjects in more creative, original ways.
In addition to this broad interdisciplinary approach, the Ordered Universe had its own teaching strand. This centred on collaborative reading of Robert Grosseteste’s De luce and De colore, along with lectures, and a successful seminar on sound given by Joshua Harvey. More intensive tutorials were run by Ordered Universe contributors Joshua Harvey and Tim Farrant, with Tom Henderson and Alexandra Haigh together tutoring a third group. Though the work was undoubtedly challenging, the sixth-formers rose magnificently to meet it, making insightful contributions. It was immensely gratifying for tutors to watch as the students grew in confidence over the course of the week, taking to heart Giles Gasper’s assurance that “there are no stupid questions”.
Students’ feedback showed that, while they found the work more difficult than they were used to, their experience of the Ordered Universe project had been immensely rewarding. It was clear that they had internalised the projects principles, looking beyond narrow conceptions of individual disciplines to be more curious and adventurous in their thinking.
The Ordered Universe project is pleased to announce its latest publication, for the Applied Optics journal, Vol. 56 (2017), G197-G204, and fully open access. The experiments and writing of the paper were led and marshalled by expertly Joshua Harvey (Mellon Foundation funded graduate student at Oxford University, Dept of Engineering Science and Pembroke college), with assistance from other members of the team, from the sciences and humanities. The paper focuses on the middle part of Grosseteste’s treatise On the Rainbow (De iride) and the shape that the rainbow forms in the sky. This precedes discussion of the colours of the rainbow, covered in other Ordered Universe papers. The current paper offers an historical context for the treatise before moving to the main discussion, testing Grosseteste’s optical thought with physical experiment and physics-based simulation. The results are available below, and show, again, the benefits of collaborative working to unlock problems posed by thinkers of the past.
The 18th Ordered Universe symposium – and the fourth held under the sponsorship of the Arts and Humanities Research Council – took place in Oxford, at Pembroke College, on 17-19 May. We were wonderfully hosted by the College, with lunches and dinners held in its magnificent Victorian Gothic hall; the symposium organisation Continue reading
