The lierne vault of JL Pearson

The lierne vault of JL Pearson

When J.L. Pearson cleared the area of the medieval cloister of the cathedral, in which he intended to build this new cloister, a series of bosses from the vaults of the 14th-century cloister was recovered. Careful examination of these bosses by Pearson allowed him to provide an archaeological reconstruction of the medieval vault, incorporating the older pieces.

Pearson built a lierne vault, in which short ornamental ribs or liernes join the main structural ribs. In this view the medieval bosses of white limestone quarried at Beer in south-east Devon may be distinguishable from the cream-grey limestone, quarried at Doulting in Somerset, used in the 1880s.
