It is not to be supposed that all lake-dwellings are of great antiquity; some are no doubt of much earlier date than others, but the question of their precise age is especially complicated from the fact that, at whatever period they were constructed, many were occupied through a long period of historic time. Crannogs are frequently mentioned in the Irish ‘Annals,’ and they enter into the composition of several place-names. Many of them suffered from the attacks of the Norsemen, as records tell us. We have clear historic evidence of the occupation of some of the lake-dwellings throughout the Middle Ages, and through the Elizabethan wars down to the middle of the seventeenth century.[120] In many, as we have seen, flint cores, with flakes, scrapers, knives, and arrow-heads, have been found. With them sometimes occurred stone celts, exactly similar to examples found in primitive cists, with burial urns and evidences of cremation. No doubt crannogs yielding flint and worked stone should be regarded as the oldest; yet from the fact that spear-heads, celts, and other articles of bronze, and even of iron, are at times found plentifully amongst their piling, or in the surrounding bog stuff, we must conclude that these islets had been used by a people well skilled in the art of metallurgy. It is necessary, too, to point out that year by year additional evidence is produced to show that in Ireland at least the apparently contemporaneous use of flint, stone, bone, bronze, and iron in the preparation of weapons, implements, and ornaments for the person, had existed throughout a long period of time. In addition to the mixed ‘finds’ already mentioned, there were found, in a Monaghan lake-dwelling described by Mr. Shirley, stone celts, a worked flint, apparently intended for an arrow-head, three looped bronze celts, a dagger and chisel of bronze, as also two bronze arrow-heads and a shield-boss of the same metal, accompanied by iron remains. At a place named ‘The Miracles,’ near Monea, Co. Fermanagh, in 1875, a lake-dwelling, the remains of which Mr. Wakeman had an opportunity of examining, was discovered by turf-cutters. Here a fairly polished axe-head, or celt, was turned up, together with a number of articles composed of bronze, which, from the description given by the people who had found them, were probably fibulæ. That, during some portion of the period of its occupation, inhabitants of this crannog were in the habit of manufacturing objects of iron was evident, as pieces of iron slag, quantities of wood charcoal, a well-formed crucible, sharpening-stones, and at least two grinding-stones were found amongst the débris. In the nearly-drained site of Loughavilly, the ‘Loch of the ancient tree,’ near Toppid Mountain, Co. Fermanagh, are the remains of a piled mound, formerly an island. Here were found a stone celt and lumps of iron slag. Traces of charcoal were abundant; but, from the softness of the surroundings, it seemed quite hopeless to penetrate to any extent into the mud or pulp in quest of discoveries.
Similar cases of ‘finds’ could be multiplied many times; it is sufficient to state that in nearly every crannog hitherto discovered, and more or less explored in Ireland, articles formed of flint or stone, and similar in every respect to remains usually assigned to the Stone Age, have occurred, and in apparent connection with implements of bronze and iron. The necessity for the use of stone celts discovered in the lake-dwellings is not clear; for it is certain that the long clean cuts which appear on the ends of the pilings or stakes by which the islands are encircled, could only have been made with sharp metallic implements of the axe or adze kind. Such objects are very common in crannog remains; and some have been found furnished with well-steeled cutting edges, while the remainder of the head consisted of soft iron. The mortice-holes so often found in the framework of the islets, and in the larger timbers of the huts, were evidently worked out by the use of metal chisels, which may have been formed either of bronze or iron.
The huts of Drumkellin and Kilnamaddo are perhaps among the earliest remains of lake-habitations yet found within the British Isles; but whatever claim they may have for classification among the earliest lake-dwellings of Central Europe, the Irish crannogs, as a whole, seem to have no such claim. And as regards these huts, ‘the relics,’ as Dr. Munro says, ‘are too few to justify such a sweeping conclusion as that these dwellings were constructed at a period when metal implements were unknown in the country. At any rate, there can be no reasonable doubt that the period of greatest development of the Scotch and Irish lake-dwellings was during the Iron Age, and at least as far posterior to Roman civilization as that of the Swiss Pfahlbauten was anterior to it.’[121]

Crannog Pottery.—The remains of fictile ware, discovered in crannogs, afford an opportunity of comparing the pottery of the lake-dwelling inhabitants with the urns used for sepulchral purposes, which are found in the cairns, cists, and tumuli. The fragments found in the lake-dwellings have been numerous; but, owing to the fragile nature of the ware, no perfect example has yet been discovered. They are larger than the cinerary urns and broader at the base. The shoulders are provided with perforated ears, affording a means of suspension by leather thong or withe. The colour of this ware varies from light drab to extremely dark brown, though a few have been found which were slightly red in appearance. The ornament which they usually bear is a chevron, or a herring-line pattern, such as are often found upon fictile ware discovered in sepulchral tumuli, as well as upon several varieties of bronze celts and other weapons or instruments. Others have dots and lines; but in general style and finish they are of a much inferior type to the cinerary urns.
Cooking-Vessel from Lough Eyes, Co. Fermanagh.
In no single instance has there been discovered a trace on crannog pottery of what might be called Christian art or design. All the earthen vessels of this class hitherto found were hand-made, and appear to have been well burnt. They are invariably unglazed; and in many examples the action of fire would seem to have been more intense internally than on the exterior. The material is invariably sandy clay; possibly the grit was added in order to afford greater consistency to the paste. Most of the vessels show this sand distinctly; and in the ruder specimens particles of white stone, occasionally the size of a small pea, and sometimes no bigger than the head of a pin, may be noticed roughly projecting from their sides. A number of flat discs of the same material as the vessels were found with them, which seemed to have been their covers or lids. A curious provision for the escape of steam during the process of boiling or cooking is observable in some of these earthen pots. It consists of a small circular aperture in the neck or upper side of the vessel, just below the point where the lid would be supported or caught. It is not possible to determine whether these vessels, when entire, were invariably perforated or otherwise; the aperture, however, occurs in some of the specimens preserved. Vessels which were of this type and exact style of ornamentation appear to be extremely rare; but they have been discovered in some districts of North America, and in Indian burial mounds of remote but unascertained date. The principal sources of this pottery in Ireland were the crannogs of Ballydoolough, Drumgay, Lough Eyes, Drumdarragh, and Lankhill, all in the county of Fermanagh; but valuable specimens have been found at Lisnacroghera, and other places. As these discoveries were subsequent to the compilation of Wilde’s Catalogue, particulars of this ware do not figure in that work.
