Note (return) — Chapter XII

Later Celtic folk-belief associated monstrous and malevolent beings with rivers and lakes. These may be the older divinities to whom a demoniac form has been given, but even in pagan times such monstrous beings may have been believed in, or they may be survivals of the more primitive monstrous guardians of the waters. The last were dragons or serpents, conventional forms of the reptiles which once dwelt in watery places, attacking all who came near. This old idea certainly survived in Irish and Highland belief, for the Fians conquered huge dragons or serpents in lochs, or saints chained them to the bottom of the waters. Hence the common place-name of Loch na piast, "Loch of the Monster." In other tales they emerge and devour the impious or feast on the dead.623 The Dracs of French superstition—river monsters who assume human form and drag down victims to the depths, where they devour them—resemble these.
