This building was erected at the close of the fifteenth century,
and was probably the second or third so raised over the
miraculous well to which came the stricken from all over broad
Scotland. It is a notable fact that since the restoration of this
chapter-house modern engineering skill has proved unequal
to the task of stemming the flow of water, which constantly
remains at the same level here. Was not this, then, the ancient
bath-house of the shrine of St Trid, down whose steps groped
the sightless in hope of the precious boon of light?

What is the mythical kernel to this saintly tale?

Firstly, be it noted, St Triduana does not figure in the
Roman calendar.
