One of the outstanding features of ancient craftsmanship in gold and bronze is the decoration of ornaments and weapons with patterns of incised lines, or with dots. Hitherto very few of the actual tools by means of which this decoration was effected have been identified, though their widespread use is proved by the very large number of specimens in our museums upon which they have been employed. Indeed, by their purely conventional use of such terms as ‘awl’ and ‘celt’ archaeologists actually blind themselves to the real nature and significance of such tools, and these notes by a metallurgical worker may accordingly serve a useful purpose in drawing attention to the true character of some of them.
