Scanning at Norwich Cathedral

This week we have been scanning at Norwich cathedral. This is the biggest site we’ve tackled to date – the whole Norman cathedral was covered with lierne vaults in the 15th century and there is also a tierceron vaulted cloister and a 14th-century lierne vault in the so-called Ethelbert Gate into the cathedral precinct.

Like other sites we have previously scanned, including Gloucester cathedral and Tewkesbury abbey, Norwich cathedral remains largely a Romanesque building, originally built as a visible symbol of the Norman Conquest of 1066. The elevations display the massive piers and round-headed arches typical of Romanesque architecture. Although undoubtedly impressive, this style would have looked very old-fashioned by the 14th century, so when the central spire blew down in 1362, damaging the east end of the building, the monks might have seen this as a good opportunity to update their church. The presbytery clerestory (top storey of windows) was rebuilt with Perpendicular tracery and, in the fifteenth century, the whole building was vaulted. The Norman walls had not been intended to carry stone vaults, so we will be interested to explore what effects these might have had on the existing fabric. Moreover, in reverse, the existing bay dimensions would have placed specific requirements on the 15th-century designers, inevitably affecting their artistic freedom.

We selected Norwich as one of our case studies for a number of reasons. Firstly, Professor Robert Willis noted that the cloister vaults showed a number of different 3D forms, despite all following the same 2D plan. Such situations – which we knew existed at Wells cathedral and have also found at Exeter – provide very interesting data for our analysis, revealing the sophistication of medieval design processes. We are therefore very much looking forward to interrogating our scan data once it has been processed. It may also provide further clues for understanding the sequencing of the cloister – the dates at which the different parts were erected – which has long been an interesting puzzle for archaeologists.

In addition, Norwich will provide an interesting comparison with Ely cathedral, as we know from documentary evidence that the same named masons worked on both sites. Members of the Ramsey family worked at Ely and Norwich in the early fourteenth century (as well as at St Stephen’s Chapel in the Palace of Westminster, whose surviving undercroft we have also scanned). Our data may help to identify whether the Ramseys and their teams used the same design methods at different sites and whether their approach was different from our other West Country vaults.

Finally, it has been argued by Frank Woodman that the vault of the Ely Lady Chapel is not 14th-century, as had always been assumed, but dates from the 15th century. He used the high vault at Norwich as a comparison for dating purposes, therefore it will be interesting to see whether laser scan data can be used to support or disprove his theory. The Norwich cathedral lierne vaults are the latest in date that we have scanned and we will be looking to see whether methods had remained constant from the 14th century or whether familiarity with the techniques had enabled improvements.

We are very grateful to all the staff at the cathedral, especially Roland Harris, the Cathedral Archaeologist, for facilitating our visit and making us feel welcome in this beautiful building.

Scanning at Westminster Abbey and the crypt of St Stephen’s Chapel

In January 2019, we travelled to London to undertake a digital survey of the medieval vaults of Westminster Abbey and the Victorian reconstructed vaults of the undercroft of the destroyed St Stephen’s Chapel beneath the Palace of Westminster using funding from the AHRC.

Westminster Abbey, perhaps the best known church in the UK, offers a number of valuable opportunities to the project. Whilst most of the hundreds of thousands of visitors each year pay homage to Britain’s illustrious dead buried there, architectural historians continue to argue over whether the nation’s mausoleum owes more to France than to England. Our research will enable us to compare Westminster’s vaulting with other sites both in the UK and in France to explore the ‘Frenchness’ of its design. Furthermore, the chapter house and cloister vaults have previously been identified as having unusual 3D geometries, so we will use our digital data to investigate this. As a royal project, Westminster is also unusually well documented in the records of the King’s Works, throwing further light on the building sequence, the identity of the designers and details of construction methods. From such records, we know that the medieval masons plotted their designs on a full size ‘tracing floor’, from which moulds were cut for the individual blocks of stone and the wooden formwork by which the ribs were supported during construction.

St Mary Undercroft, formerly the crypt of St Stephen’s Chapel in the Palace of Westminster and now the place of worship for the Houses of Parliament, is another well-documented royal work, started by Edward I. Its vaults take an innovatory ‘lierne’ form, with extra decorative ribs which have been claimed as the earliest liernes in England. Although now largely a Victorian reconstruction following the great fire of 1837 which destroyed most of the medieval palace, measurements were taken from the medieval vaults prior to demolition. Our digital survey will be used to compare the measurements of the demolished medieval design with the current Victorian reconstruction and possibly identify elements of original medieval fabric lurking beneath the Byzantine-style paintwork.

The two surveys add to a growing list of case study buildings that will be individually analysed, as well as offering comparisons between sites. We are currently making good progress with analysis at Exeter, Ely and Wells cathedrals, and will begin investigations using the Westminster Abbey and St Stephen’s Chapel data later this year.

A celebration of the life and work of Richard K. Morris

On Saturday 20 March, Alex went to London to attend a study day at the Courtauld Institute, organised by the British Archaeological Association and the Ancient Monuments Society to commemorate Richard K. Morris (1943- 2015), whose work on Decorated architecture in England is very relevant to our project. Richard specialised in the detailed archaeological analysis which is an essential counterpart to our own research and specialised in the study of West Country buildings. His methodology involved the use of mouldings to reconstruct both building chronologies and the careers of individual masons and offered readings of such buildings as Wells Cathedral, Exeter Cathedral, St Augustine’s Abbey at Bristol, Tewkesbury Abbey and Sherborne Abbey, all of which have significant vaults.

The study day offered a varied programme including both new and established scholars. Of particular interest for our project were papers by James Cameron and Peter Draper which discussed medieval architectural drawings: both those which survive (a huge archive of drawings cut on the rocks around an 11th-century temple in Bhojpur, India) and those whose one-time existence might be suggested by the evidence of buildings whose detailed similarities are hard to explain.

Another relevant paper by James Hillson discussed the lierne vault of St Stephen’s Chapel Westminster, which he identifies as a design of the 1340s, rather than the 1290s as most previous interpretations have suggested. The problem is compounded by the loss of the original vaults after the fire at the Palace of Westminster in 1834, although detailed drawings were made and measurements taken by architect Charles Barry and communicated to Robert Willis for his research. If Hillson is right, this redating would mean that the Westminster designs can no longer be identified as the earliest true lierne vault and its relationship with other lierne vaults, such as those at Exeter, Bristol and Wells could be reversed, for the lierne vaults at Wells date from around 1330 and those at Exeter are earlier. The dating of the Bristol vaults remains a matter of controversy, into which Hillson opted not to wade.

Finally, vaults made a virtuoso appearance in a paper by Andrew Budge, who spoke on the chancel at St Mary’s Warwick, which has a tierceron vault with additional ‘skeleton’ ribs. Although Budge drew attention to a number of English examples of such vaulting, at St Augustine’s Bristol, the pulpita (screens) of St David’s Cathedral and  Southwell Minster, the Easter Sepulchre of Lincoln Cathedral, stairway vaults at Thornton Abbey and Wells Cathedral and around the apse of Peterborough Cathedral, he also pointed out their existence in the so-called ‘tonsura’ at Magdeburg Cathedral. It was suggested that Thomas Beauchamp, 11th Earl of Warwick (1313-1369), who was buried in the chancel, might have visited Magdeburg en route to or from crusading activities and that the inclusion of skeleton vaults above his tomb might therefore represent an aspect of a ‘biography’ in stone. This of course offers some of the same problems about knowledge transfer as had already been addressed by James Cameron in relation to near-duplicate designs for sedilia. Whatever their meaning, these vaults amply demonstrate the exuberant inventiveness of architects of the Decorated period, whose methods we are seeking to explore.

Overall the day offered a wonderful opportunity to pay tribute to the work and influence of a kind and generous scholar with exemplary commitment both to his subject and to future scholarship.
