Origins
The sculptures date from classical antiquity and have been attributed to the 4th century BC Greek sculptor Lysippos, although this has not been widely accepted. Although called bronze, analysis suggests that as they are at least 96.67% copper, they should be seen as an impure copper rather than bronze. The high tin content increased the casting temperature to 1200-1300 °C. The high purity copper was chosen to give a more satisfactory mercury gilding. Given current knowledge of ancient technology, this method of manufacture suggests a Roman rather than a Hellenistic origin.

Famous quotes containing the word origins:
“Grown onto every inch of plate, except
Where the hinges let it move, were living things,
Barnacles, mussels, water weeds—and one
Blue bit of polished glass, glued there by time:
The origins of art.”
—Howard Moss (b. 1922)
“The settlement of America had its origins in the unsettlement of Europe. America came into existence when the European was already so distant from the ancient ideas and ways of his birthplace that the whole span of the Atlantic did not widen the gulf.”
—Lewis Mumford (1895–1990)
“The origins of clothing are not practical. They are mystical and erotic. The primitive man in the wolf-pelt was not keeping dry; he was saying: “Look what I killed. Aren’t I the best?””
—Katharine Hamnett (b. 1948)
