the Ellennith mountains, and separating the Cantref Mawr from the
Cantref Bachan, passes by the castle of Llanymddyfri, and the royal
palace and castle of Dinevor, strongly situated in the deep
recesses of its woods, by the noble castle of Caermarddin, where
Merlin was found, and from whom the city received its name, and
runs into the sea near the castle of Lhanstephan. The river Taf
rises in the Presseleu mountains, not far from the monastery of
Whitland, and passing by the castle of St. Clare, falls into the
sea near Abercorran and Talacharn. From the same mountains flow
the rivers Cleddeu, encompassing the province of Daugleddeu, and
giving it their name one passes by the castle of Lahaden, and the
other by Haverford, to the sea; and in the British language they
bear the name of Daugleddeu, or two swords.

The noble river Teivi springs from the Ellennith mountains, in the
upper part of the Cantref Mawr and Caerdigan, not far from the
pastures and excellent monastery of Stratflur, forming a boundary
between Demetia and Caerdigan down to the Irish channel; this is
the only river in Wales that produces beavers, an account of which
is given in our Itinerary; and also exceeds every other river in
the abundance and delicacy of its salmon. But as this book may
fall into the hands of many persons who will not meet with the
other, I have thought it right here to insert many curious and
particular qualities relating to the nature of these animals, how
they convey their materials from the woods to the river, with what
skill they employ these materials in constructing places of safety
in the middle of the stream, how artfully they defend themselves
against the attack of the hunters on the eastern and how on the
western side; the singularity of their tails, which partake more of
the nature of fish than flesh. For further particulars see the
