But the special interest of the Lisnacroghera crannog lies in the remarkable series of military weapons which it has yielded, consisting of iron swords and ornamented sheaths of bronze, iron spears with long wooden handles and bronze mountings, together with a variety of other bronze objects, probably the mountings of shields. These I shall now proceed to describe. [Illustration: =Fig. 123.=--LISNACROGHERA. Sword Sheaths of Bronze. All ½ real size.] _Sword-sheaths._--Up to the present time four sheaths (=Fig. 123=, Nos. 1 to 4) have been recovered, but only one is entire, the rest being more or less in a fragmentary condition. They are all made of thin bronze riveted together at the margins, and over this there is a bead which, towards the lower third, develops into an elegant ornamentation very similar to that which we have already seen on the sword-sheaths of La Tène (See =Fig. 87.=) The perfect sheath (No. 1) is devoid of ornamentation, except that formed by the marginal bead; but the other three (of which only one side of each remains) are decorated with highly artistic designs formed by incised lines, the details of which will be readily seen from the illustrations. No. 1, which still retains the blade of an iron sword firmly adhered to it, is 17½ inches long. No. 2 is defective at the tip, besides having lost its surrounding bead; it measures, in its present condition, 19 inches in length. The illustration here is a reproduction of a rubbing reduced half size and shows only the upper half. The design which comes out in white lines is in reality incised lines and corresponds to the dark lines in the other two. No. 3, the largest of the group, measures 22 inches in length. Both ends are here represented. No. 4 is the smallest, being only 16½ inches in length. It is supposed that the incised lines, which are sharply defined and deeply cut, contained a black enamel, but no traces of it now remain. The circular cavities in the surrounding bead at the tips were also intended for the reception of enamel, probably of some brilliant colour. These designs, which belong to the so-called "late Celtic" style of ornamentation, when so treated must have had a striking effect on the bright bronze surface. In Nos. 1 and 4 it will be observed that there is a transverse raised band, the purpose of which was, no doubt, to strengthen the sheath. Such bands were a feature in the La Tène sheaths, which in some instances were repeated several times at intervals on the body of the sheath. In Canon Grainger's collection I saw one or two broad rings compressed in the middle, which I took to be the cross-bands of other sheaths. [Illustration: =Fig. 124.=--LISNACROGHERA.
