Extract

Two recent studies by A. R. Giumlia-Mair and P. T. Craddock have been devoted to a form of bronze having a blackish tint.1, 2 The authors there describe examples ancient and modern, from as far apart as Mycenean Greece, Egypt, Rome, China and Japan. In Japan such bronze is prominently represented in decorative art and known as Shakudo.

7 Apart from these references to continuous substances, Pliny also uses mixtura of smells (17.239), light and colour (11.148; 35.30, 46; 37.80), or simply of a list of varied items (2.241). At 8.213 he uses mixtura of animal breeding, and at 16.46 he writes of trees that are closely inter-related: tanta natalium mixtura est, while at 17.187 he warns against the planting of different vines in close proximity as mixtura generum. Pliny also uses mixtura meteorologically, of a blend of heat and moisture (2.190); in the same way the colours of the rainbow are due to the mixtura of clouds, fire and air (2.150). None of these instances, of course, in any way support the view that mixtura could indicate a combination of one metal (Corinthian bronze) juxtaposed with others (gold and silver) in which each retains its characteristic properties including colour.
