There are specimens of the other Late-Celtic objects of unknown use—namely, the hook-and-disc ornaments[250] and the circular pieces of repoussé metalwork with a cup-shaped depression—in the British Museum[251] and the Dublin Museum.[252] [250] _The Reliquary_ for 1901, p. 56. [251] _Proc. Soc. Ant. Scot._, vol. xix., p. 254. [252] Sir W. Wylde’s _Catal. Mus. R.I.A._, p. 637. No satisfactory explanation has been given of the use of certain wheel and triskele pendants of which examples have been found in Berkshire, Kingsholm, near Gloucester, Hunsbury, N. Hants, Seamill Fort, Ayrshire, and Treceiri, Carnarvonshire. POTTERY AND GLASS The pottery of the Late-Celtic period differs from that of the Bronze Age in being turned on a wheel instead of being handmade. The firing is also better done, and the quality of the ware superior in every way. Since the discovery of the Aylesford cemetery in Kent, in 1886, it has been possible to differentiate Late-Celtic pottery from Romano-British by the peculiar forms of the vases. Dr. Arthur Evans has dealt with this subject pretty exhaustively in his paper in the _Archæologia_ (vol. lii., p. 315). The most characteristic of the Aylesford urns is tall, with a narrow base and wide mouth. The base is in the shape of a low truncated cone, the top of which is the narrowest part of the vase, and from this point it gradually gets wider until the top rim is nearly reached, when it contracts again slightly. The curve thus produced is of such extreme elegance as to at once suggest a classical origin. The exterior surface of some of these pots is plain, but in many cases it is divided into bands by horizontal projecting bead mouldings. Dr. A. Evans does not find much difficulty in showing that the peculiarities of form can be directly traced to the metal _situlæ_ from which the vases were copied. With regard to this, he says:— [Illustration: LATE-CELTIC POTTERY FROM HUNSBURY; NOW IN THE NORTHAMPTON MUSEUM] [Illustration: LATE-CELTIC POTTERY FROM HUNSBURY; NOW IN THE NORTHAMPTON MUSEUM] [Illustration: Late Celtic urns from Shoebury, Essex Now in the Colchester Museum]
