[Rare earth elements]
 
   The early Greeks defined earths as materials that could not be changed further by the sources of heat then available. Until late in the 18th century, this Greek conception remained strong in chemistry, and oxides of metals such as calcium, aluminum, and magnesium were known as earths and were thought to be elements.The history of the discovery and naming of the REE wasreviewed by abashi (1994a, 1994b) and is summarised inTable 1.
