Presbytery Ceiling - The great vault forming the Presbytery ceiling was constructed in the thirteenth-century.
Sent by Marina from London, England.
The presbytery vault at St Albans is one of only two thirteenth-century wooden vaults over a main span to survive in England. A programme of cleaning and conservation carried out between 1997 and 2002, coupled with an analysis of the source and date of the timber used in its construction, significantly advanced our understanding of both the late thirteenth-century presbytery campaign at St Albans and thirteenth-century timber vault construction generally. As the inevitable density and restricted circulation of the final report on that work has hindered its wider reception, the following paper offers a summary, drawing attention to two features that may have wider implications for an appreciation of vaulting in timber. The first is that, although the general form adopted at St Albans is one associated with masonry vaulting, the wooden boards used for the vault webbing required a junction between the wall and the ridge rib, meaning that shallow liernes were originally deployed to run parallel to the central ridge. It is difficult to see this as imitative of vaulting in stone; rather it is likely to be the result of carpenters developing their own solutions to the constraints imposed by timber. Secondly, the late medieval remodelling of the vault replaced these liernes with false tiercerons, and rather nicely illustrates the ease with which timber vaulting could be modified.
The dendrochronology gives a date range of 1273–93, and a date of around 1285 is suggested for the primary build. The major late medieval alterations are here associated with the second abbacy of John of Wheathampstead (1452–65) (read more).
