| Abstract: | Before the 1978 excavation of the chapter-house site directed by Martin Biddle and the late Birthe Kjølbye-Biddle, nothing was known about the 15th-century building, beyond the brief documentary references in the Register to its remodelling during the second half of the century in the time of abbots John of Wheathamstead and William Wallingford. However, the exceptional quantity of late Gothic masonry fragments uncovered during the excavation has made it possible to attempt to reconstruct features of its design, particularly the vaulting, and has transformed our knowledge of this important building. This article reviews the information derived from the study of the fragments of the vault, assesses its significance in the development of late Gothic vaulting, and speculates on the identity of its designer. |
