Like lead or cadmium, mercury is a constituent element of the earth, a heavy metal. In pure form, it is known alternatively as “elemental” or “metallic” mercury (also expressed as Hg(0) or Hg0). Mercury is rarely found in nature as the pure, liquid metal, but rather within compounds and inorganic salts.
Documentation of the first snowman is unclear. However, Bob Eckstein, author of The History of the Snowman documented snowmen from medieval times, by researching artistic depictions in European museums, art galleries, and libraries. The earliest documentation he found was a marginal illustration from a 1380 book of hours, found in the Koninklijke Bibliotheek in The Hague. The earliest known photograph of a snowman was taken in 1853 by Welsh photographer Mary Dillwyn, the original of which is in the collections of the National Library of Wales.
