Kongsberg Silver-miner's Lamp

This is a replica of a miner's lamp used in the 1600 and 1700's in the Kongsberg, Norway Royal Silver Mines. It hangs in the fireplace in our home. I used to live 250 miles away in Hoyanger but I now visit Kongsberg regularly as my friend of 50 years now lives there.
Tallow from sheep, goats and cattle were used to fill the lamps to provide light in the mines. One can only imagine what it was like to work in such a dim light.
The silver was found by two children who were bringing an ox down from the mountain. The ox scraped the ground with a horn and the children saw a shiny substance in the ground which they dug up and took home and gave to their father.
In 1724 the Danish King Christian IV claimed it for himself (Norway was then ruled by Denmark) and the area was then called Kongsberg or King's Mountain.
Nearly 1500 tons of silver was extracted before the mines closed in 1957.
