use), it is not a matter of so much wonder; for although by our
great authority we commit acts of violence and wrong against these
people, yet they are known to be the rightful inheritors of this
land."

The lake also {54} (according to the testimony of the inhabitants)
is celebrated for its miracles; for, as we have before observed, it
sometimes assumed a greenish hue, so in our days it has appeared to
be tinged with red, not universally, but as if blood flowed
partially through certain veins and small channels. Moreover it is
sometimes seen by the inhabitants covered and adorned with
buildings, pastures, gardens, and orchards. In the winter, when it
is frozen over, and the surface of the water is converted into a
shell of ice, it emits a horrible sound resembling the moans of many
animals collected together; but this, perhaps, may be occasioned by
the sudden bursting of the shell, and the gradual ebullition of the
air through imperceptible channels. This country is well sheltered
on every side (except the northern) by high mountains; on the
western by those of cantref Bychan; {55} on the southern, by that
range, of which the principal is Cadair Arthur, {56} or the chair of
Arthur, so called from two peaks rising up in the form of a chair,
and which, from its lofty situation, is vulgarly ascribed to Arthur,
the most distinguished king of the Britons. A spring of water rises
on the summit of this mountain, deep, but of a square shape, like a
well, and although no stream runs from it, trout are said to be
sometimes found in it.

Being thus sheltered on the south by high mountains, the cooler
breezes protect this district from the heat of the sun, and, by
their natural salubrity, render the climate most temperate. Towards
