Knowing and Speaking…


News on the first volume of six from the Ordered Universe presenting the scientific works of Robert Grosseteste. The first volume is avialable for pre-order from both the Oxford University Press website and at Amazon (UK and others). The first volume has a shipping weight of 739 grams and is 640 pages in total, and features 19 co-authors (it is not an edited volume but a co-authored monograph, under the aegis of Ordered Continue reading

Ordered Universe at the Leeds IMC

OU Leeds 2019 Simple

As followers of the Ordered Universe will know the project will be represented in four sessions and a round-table at the International Medieval Congress in Leeds. All sessions take place on Tuesday 2nd July, and work around the conference theme of materiality. We move from the physics of light and dimensions of materiality, to theories of vision, Continue reading

On the new edition of Grosseteste’s Compotus

The medieval ecclesiastical calendar rested on the foundation of two interlocking calendrical cycles, which were represented by the Julian calendar, with its 28-year cycle of weekdays, and by a 19-year cycle of ‘epacts’ for tracking the phases of the Moon. Monks and clerics who sought to learn more about the scientific background of these cycles, or simply to familiarize themselves with their use, could do so by turning to books Continue reading

Movement Terrestrial and Celestial




Our next Ordered Universe symposium, the eighth under the aegis of our current funding from the UK Arts and Humanities Research Council, and 24th overall in a series stretching now over a decade, takes place 13-16 May, at Bishop Grosseteste University in Lincon. It has been a fascinating journey, and from tomorrow, we broach the two treatises remaining for all of Grosseteste’s shorter scientific works to have been edited, translated, and patiently and collaboratively read. On Lines, Angles, and Shapes, and On the Nature of Places, brings the canon to its completion, with reading on-going for On the Movement of Celestial Bodies, and a final read-through of On Bodily Motion and Light. Two symposia remain for our current sequence which will revise the latest treatises and revist On Colour and On the Rainbow.

The programme for the symposium is available for downloand here and online:


It is a great pleasure to be back at Bishop Grosseteste University. BGU has been a fabulous partner, supporter, and advocate for the Ordered Universe project, principally through the energy and tremendous good offices of Dr Jack Cunningham. We will look forwad to the hospitality and welcome at BGU, and getting on to the most stimulating experience of collaborative reading and exploring the world of early 13th century science.




Public Lecture in Lincoln

OUP POster

Our next project symposium takes place in Lincoln, and we’re delighted to be back in the convivial surroundings of Bishop Grosseteste University, hosted by Jack Cunningham and the BGU Ordered Universe chapter. As part of the symposium, which features Grosseteste’s treatise On Lines and Angles, On the Nature of Places, alongside On the Supercelestial Motions and On Bodily Motion and Light, we have a public lecture on Grosseteste’s cosmology and its implications for understanding of the world. The three Continue reading

A little over a week ago the OxNet-Ordered Universe 2019 Easter School brought the 2019 cohort of school students aged 16-17 (Lower Sixth Form, Year 12) from the North-East, to a 2-day residential experience at Durham University. Students from Southmoor Academy, St Anthony’s, St Robert of Newminster, and Park View Academy, came together at venues around Durham including Collingwood College, Palace Green Libary, Durham Castle (University College Durham), the Institute for Particle Physics Phenomenology, and the Institute for Computational Cosmology to think about the topic of ‘Light, Colour, and the Cosmos: Exploring Themes in Medieval and Modern Science’.

OxNet North East co-ordinator, Claire Ungley shared the following thoughts on the Easter School in her report below:

Aristotle’s Physics in Paris and Oxford, in Rome

News of a day-conference taking place in Rome, at the University of Rome, Tor Vergata, on Aristotle’s Physics in Paris and Oxford in the course of the thirteenth century. Organised by Professor Cecilia Panti (Tor Vergata) speakers include Nicola Polloni of the Humboldt University, both Ordered Universe regulars. With Bacon, Albert the Great, Grosseteste, and much more besides, the conference promises to be both fascinating and stimulating.

Locandina Fisica nel Medioevo

UCL – Scientific Works of Robert Grosseteste

Giles Gasper (Durham University) will be giving a talk later today to the Interdisciplinary Medieval and Renaissance Seminer at University College, London, 6.15-7.15 on ‘The Scientific Works of Robert Grosseteste’. Giles will be talking about the work of the Ordered Universe project, its collaborative research methods, and larger questions concerning the whole corpus of scientific works produced by Grosseteste c. 1195-c.1230. Many thanks to Jack Ford for the invitation.

New Publication

A new publication from Ordered Universe science colleagues Josh Harvey, Hannah Smithson and Rebekah White, inspired, in its first stages, by the collaborative reading of Grosseteste’s On the Generation of Sounds, and its emphases on different types of motion, and the relation of written letters to the shape of the vocal tract in voicing the letter. ‘Hand-Foot Coupling: An Advantage for Crossed Legs‘ is published in Perception, and makes fascinating reading.
