eCAADe 2016 – Tracing the Past presentation

At eCAADe 2016 (Education and research in Computer Aided Architectural Design in Europe) in Oulu, Finland, Nick presented a paper co-authored with Alex and JR discussing the advantages of different digital surveying methods for the project. The paper can be found via CUMINCAD here.

A contextualised digital heritage workshop led by Danilo Di Mascio was also organised, with help from Anetta Kepczynska-Walczak and myself, the details of which can be found here. We were very grateful for the support given by the University of Oulu, and were encouraged by the discussions held with participants, which provided an enjoyable couple of days leading up to the main conference. We hope to run the workshop again at eCAADe 2017 in Rome!



Tracing the Past was inspired by the work of Robert Willis (1800-1875), a famous Cambridge polymath. He was Jacksonian Professor of Natural and Experimental Philosophy and taught engineering in the early years of that subject.

Willis’s research and teaching was spread over a wide range of
subjects. Our particular interest is in his pioneering study of medieval vaulting, presented as a lecture to the Royal Institute of British Architects in 1841 and published in the first volume of their Proceedings in 1842. Willis proposed a number of hypotheses about the design of medieval vaults which he hoped contemporary architects would be able to test. However the difficulties of gathering suitable data were huge and it’s only now, with the introduction of laser scanning that his ideas can be more fully explored, through projects such as ours.

On 16-17 September 2016, both Nick and Alex will be giving papers in the Robert Willis: Technology, Science and Architecture symposium taking place at Willis’s own college, Gonville and Caius College, Cambridge. Alex will be speaking on Willis’s networks of knowledge and Nick will be presenting a digital update of Willis’s 1842 paper, for which the digital content can be found here. Other speakers will also be discussing Willis’s work on vaults, including Prof Santiago Huerta, Javier Giron, Martin Bressani (speaking on Willis and Viollet-le-Duc) and Antonio Becchi. The full programme is available here: willis-program-a4

The Symposium website includes a digital library of Willis’s publications, making it an incredibly useful resource for those sharing his interests. The Symposium proceedings will be published – further details available soon.




We’re off to Ely!

Ely Cathedral Presbytery
Ely Cathedral Presbytery

We already reported that the Society of Antiquaries of London have very generously funded a trip to Ely Cathedral, where we shall be scanning the vaults in the Presbytery, the Lady Chapel, the Octagon and Prior Crauden’s Chapel. We’ve now got permission from the Cathedral authorities to go ahead and we’ll be at the Cathedral on 13-14 September. As well as laser scanning, we’re going to be experimenting with total station.

The Lady Chapel was started in 1321 but attention moved when the crossing collapsed, in 1322, and the whole area had to be rebuilt. We know the vaults of the Presbytery were complete by 1337, when there were payments for painting them. Thus the work is exactly the same date as the vaults at Wells.

So far we’ve only scanned vaults in the west of England, so this will be our first opportunity to scan vaults in East Anglia, where design principles and construction methods might be very different. The Ely designs are associated with William Hurley, the King’s master carpenter, who designed the wooden vaults of the Octagon and William Ramsey, later the chief surveyor of the King’s works in the Tower of London and other castles south of the Trent, to whom the later parts of the design have been attributed on stylistic grounds.¬† The Ramsey family of masons were closely associated with the Royal Works and with East Anglian architecture, including the cloister of Norwich Cathedral, which also has lierne vaults showing a variety of rib curvatures, as in the aisles of Wells.

The vaults of Prior Crauden’s Chapel are of interest to us because they are not medieval but were reconstructed by Robert Willis in the 1840s. They were thus an opportunity for him to put into practice the ideas he had explored in his 1841 lecture ‘On the Vaults of the Middle Ages’.
