Gold, in Greek mythology, is connected with countries of the East: even today the Paktolos of Chrysorroa River is spoken of, the sand of which came mixed with the precious metal. Besides the gold dust of the rivers that contained silver, mineral gold was also to be found in the veins of rocks. Various sources of gold are mentioned as existing on Greek territory but all were poor and soon exhausted. The study of golden objects (jewels, coins, textiles, painting mosaics) can supply us with extensive information about the techniques used in antiquity. The various techniques that are exclusive to a goldsmith were developed quite early on (ex. filigree and granulation).
