The ribs of the vault are moulded, and there is a ridge rib running
round, with bosses and shields at the junctions with the other ribs (see
Fig. 1427). The ribs spring from the caps of the central pillar and the
caps of shafts in the angles. The style of the carving of these caps and
the foliage of the bosses is evidently of the third or late period (Fig.
1429). From its use as a sepulchral vault the floor has now been greatly
filled up with earth, which rises almost to the caps of the central
shaft and wall shafts.
It is not known when the turf was piled up over the roof, but it is very
desirable that it should be removed, and the windows opened up, and the
interior cleaned out. It would then be seen to be, as Mr. Laing says, “a
charming specimen of the architecture of the fifteenth century.”
