Why is the natural world saturated with constant movement, and how do we make sense of this perpetual fluctuation of material things? What principles and methods are most suited to find order and coherence in this ever-changing world? From May 13th to 16th, the Ordered Universe gathered at Bishop Grosseteste University in Lincoln to read, analyse, and debate Robert Grosseteste’s answers to these questions in a series of texts. The scope of these texts ranges from the geometrical and optical principles of natural causality in the twinned treatises On Lines, Angles, and Shapes and On the Nature of Places, via the labyrinthine search for the unifying causal factor in bodily movement in On Bodily Movement and On Light, to the condensed metaphysics of On the Movement of Supercelestial Bodies. If the principles of heavenly movement remained obscure, the clear skies allowed the rays of the sun full freedom to give leafy Lincoln a summery sparkle. The staff and amenities at Bishop Grosseteste University were as welcoming as the weather, and provided ideal surroundings for activity and movement as well as for rest.
As always, our twofold task was to beat draft translations into shape and figure out what arguments the sometimes highly obscure Latin texts were meant to establish. We were fortunate to have in our midst scholars from a range of discipline corresponding to the breadth of Grosseteste’s interests and talents. BGU did not only contribute hospitality but also scholarship, in the form of Dr Jack Cunningham and his PhD students Ros Gammie and Adam Foxon at the theology department at BGU, and Dr Gioacchino Curiello, who is a British Academy Post-Doc at the same department. Gioacchino also brought some welcome variation into our work schedule through presenting his ongoing research on Grosseteste’s translations of and commentaries on the Pseudo-Dionysian corpus of texts, and how these can be linked to his pastoral care as Bishop of Lincoln.
The texts we worked on this time draw heavily on geometry and optics to explain natural phenomena and natural causation. Professors Tom McLeish from York and Brian Tanner from Durham produced extremely helpful diagrams of the reasoning implicit and explicit in the texts, and Oxford Vision Scientists Professor Hannah Smithson and Dr Rebekah White brought clarity and focus to our reading by refracting Grosseteste’s opaque words through the lenses of their expertise. Professor Clive Siviour and Joshua Harvey, also of Oxford, showed how useful their training in Engineering and, in Josh’s case, Experimental Psychology, is for elucidating medieval texts with precision.
Professor Cecilia Panti (Rome, Tor Vergata) had produced wonderful new editions of On Lines, Angles, and Shapes and On the Nature of Places, and Dr Neil Lewis’s (Georgetown) translation of On the Movement of Supercelestial Bodies was based on Cecilia’s already published edition of that work. We also revisited Neil’s meticulous edition and translation of On Bodily Movement and On Light, which continues to fascinate and puzzle us. Since these texts draw heavily on other medieval works, we were delighted to welcome back Dr Nicola Polloni (Berlin) and Dr Seb Falk (HPS, Cambridge), who made essential contributions from their expertise, respectively, in medieval philosophy and medieval science. Dr Sarah Gilbert, who recently completed her PhD in History at Durham, had helped organise the workshop and added her valuable Latin skills to her administrative contributions. We were also joined by Karen Monid of The Projection Studio. Karen and Ross have used Grosseteste’s texts as inspiration for their wonderful projection shows, using the movement of light and of sound to make the most profoundly moving projection shows. We are very much looking forward to seeing what this creative team will do next!
Grosseteste assumed as axiomatic that a unitary effect must have a unitary cause and origin. The union of these disciplines in a unitary debate, while dependent on all participants, can be traced back to the unifying leadership of Professor Giles Gasper (Durham), who once again managed to make numerous disparate impulses and energies pull in the same direction. Giles also gave a public lecture, together with Sig Sønnesyn (Durham) and Cecilia Panti, with the title ‘Creation and the World Machine: 13th Century Science and Theology’. In this lecture, Giles framed Grosseteste’s life and work within the overarching theme of creation theology and natural science. Sig gave a case study of this from the perspective of the short treatise On the Six Differentiae, and Cecilia presented her recent edition of a text, quite possibly and plausibly authored by Grosseteste, on the importance of astronomical time-keeping for the art of medicine and healing.
One of the central lessons of Grosseteste’s geometrical account of natural causality is that while a single rectilinear influence from cause to effect can be effective, the effect is many times stronger when several such lines converge on the same point to concentrate their efforts. This workshop, converging on Grosseteste’s episcopal seat and final resting place, has reminded us how this is applicable, with the necessary modifications, to scholarship as well. By coming together to concentrate our efforts towards a shared goal, we were able to produce effects that none of us would have been capable of on our own. Grosseteste would not have been surprised at this, convinced as he was that nature is the best guide for art and academic pursuits.
