Demogorgon

A pseudo-Greek mythological figure most likely actually invented by a Christian scholar ca 350-400 CE. The origins of the name are uncertain, partly because the figure itself was possibly of imaginary coinage. Various theories suggest that the name is derived from the Greek words daemon ('spirit' given the Christian connotations of 'demon' in the early Middle Ages)— or, less likely demos ('people')— and Gorgon or gorgos ('grim'). A less accepted theory claims that it is derived from a variation of 'demiurge'.

   (Can we find and add a quotation of Milton to this entry?)
