The next Ordered Universe symposium takes place in the week to come, May 17-19, at Pembroke College, University of Oxford. It will be great to be back at Pembroke, one of the original homes of the project, and to be broaching two new treatises for collaborative reading. These comprise the De cometis – On Comets and the De impressionibus elementorum; the latter connected to argument on the genesis, nature and activity of comets, the latter a discussion of meteorological phenomena, mostly watery (dew, hail, snow and rain). The reading sessions will be using the edition of the De cometis by Cecilia Panti, with translations of the two works, and a draft edition of the De impressionibus by Sigbjørn Sønnesyn. We will be welcoming some new participants to the group, as well as Ross Ashton and Karen Monid from the Projection Studio. The treatises under scrutiny reveal Grosseteste more at home with Aristotelian methodology, and articulating a more scientific approach to physical problems. Key aspects of his thought on sublimation, on light and on grounds for verification and falsification make their appearance, as do a range of different sources alongside Aristotle. The symposium organisation is principally by the Oxford team, under Hannah Smithson, and the project is extremely grateful to the efforts of Joshua Harvey, Tim Farrant and Clive Siviour, as well as the College conference staff. Set course for Oxford and we’re off! Look out for reports on the progress of the meeting – a copy of the programme is appended here in PDF and also available at Issuu.
