By the ancient alchemists, gold represented the sun, and silver the moon. In heraldry, gold is expressed by dots.
“In manu illius plumbum aurum flebat.” —Petronius.
“All thing which that schineth as the gold is nought gold.”
Non teneas aurum totum quod splendet ut aurum Nec pulchrum pomum quodlibet esse bonum.
Alanus de Insulis: Parabolæ.
He has got the gold of Tolosa. His ill gains will never prosper. Cæpio, the Roman consul, in his march to Gallia Narbonensis, stole from Tolosa (Toulouse) the gold and silver consecrated by the Cimbrian Druids to their gods. When he encountered the Cimbrians both he and Mallius, his brother-consul, were defeated, and 112,000 of their men were left upon the field (B.C. 106).
