that of other red stones, it is yet believed that the
Anthrax
of the Greek Philosopher Theophrastus must have been the mineral which we recognise as Ruby ; whilst the
Carbunculus
of Pliny probably included this and other stones of a somewhat similar character. The Anthrax was so called in allusion to its vivid colour, suggestive of that of a live coal, and the word Carbunculus likewise referred to its fiery appearance. Of the various kinds of Carbunculus known to the Ancients, the most valuable was that termed
Lychnis,
in consequence of its lustre resembling that of a lamp. It is curious to note that many old writers seem to have believed in the self-luminosity of the Ruby and other red stones. Thus, the quaint old writer Sir John Maundeville, describing his travels in the East in the fourteenth century, says with regard to the many marvels of the Court of the Great Chan of Cathay, " This Emperor hath in his chamber, in one of the pillars of gold, a Ruby and a Carbuncle of half-a-foot long, which in the night gives so much light and shining, that it is as light as day." This statement however may be laid to rest with the numerous other travellers' stories to be found in the pages of the credulous old knight.
Before Mineralogy became a science, and could call to its aid the services of Chemistry and Physics, it was by no means surprising that various stones of red colour should be confounded together ; thus the Spinel or Balas, and the Garnet were often mistaken for thé true Ruby. The only stone, however, to which the term Ruby in scientific strictness can be applied is a variety of the mineral-species termed
Corundum.
The name Corundum is derived from the Hindu word
Kurandy
and it is most probable that it first became known in Europe from the stone having ' been imported from
