I have myself celts of the same class from the Cambridge Fens (4⅝ inches); Sherburn Carr, Yorkshire (5⅝ inches), found with another nearly similar; Swansea (4¼ inches, much decayed); and near Pont Caradog, Brithder, Glamorganshire (6¼ inches), found with three others, and given to me by Canon Greenwell, F.R.S., in whose collection the others are preserved. A few of these flat plain celts have been found in France. Some from the departments of Doubs and Jura are engraved by Chantre.[171] One from Normandy,[172] figured by the Abbé Cochet, seems to show some trace of a transverse ridge. One from the Seine is engraved in the “Dictionnaire Archéologique de la Gaule.” Another was found in Finistère.[173] Others are in the Museum at Narbonne[174] and elsewhere. The form is also found in Spain, both in bronze and what is apparently copper. I have specimens from the Ciudad Real district. The plain flat form like Fig. 2 is also occasionally found in Germany. One from Ackenbach, near Homberg, is figured by Schreiber.[175] With nearly straight sides like Fig. 27, the form is not uncommon in Hungary. Some of these are very thin. Others of nearly the same form, but thicker, have been found on the other side of the Atlantic in Mexico, and many of the copper celts of North America are also of the plain flat type with an oblong section. This circumstance to my mind rather proves that the form is the simplest, and therefore that most naturally adopted for hatchets, than that there was of necessity any intercourse between the countries in which it has prevailed. Many of the flat celts are ornamented in a more or less artistic manner on the faces, or the sides, or on both; but before proceeding to notice any of them, it will be well to mention another variety of the plain celt, in which the faces, instead of being nearly flat or uniformly convex, slope towards either end from a transverse ridge near the middle of the blade. This ridge is never very strongly defined, as the total thickness of the blade from ridge to ridge is rarely more than half an inch. The plain variety is somewhat rare in Britain, but one ornamented on both faces will be described, under Fig. 5, and an Irish example is shown in Fig. 35. A large doubly tapering celt (8 inches) was found at East Surby, Rushen,[176] Isle of Man. Some of those already mentioned partake of this character. In Hoare’s great work a specimen from the Bush Barrow, Normanton,[177] is engraved as being of this plain doubly tapering type; but from the more accurate engraving given by Dr. Thurnam[178] it appears that this instrument has flanges at the side, like Fig. 8, and must therefore be spoken of later on.
