"Liv'd there such a thing as bliss;
Skies that now are dark were beaming
Gold and azure, splendid seeming
Till I learn'd it all was dreaming-
Deadly drowsiness of Dis"
H.P. Lovecraft, Despair
"HAIDES was the King of the Underworld, the god of death and the dead. He presided over funeral rites and defended the right of the dead to due burial. Haides was also the god of the hidden wealth of the earth."
"Haides was depicted as a dark-bearded, regal god. He was depicted enthroned in the underworld, holding a bird-tipped sceptre."
Aaron J. Atsma, The Theoi Project: Greek Mythology
We possess few representations of this divinity, but in those which still exist, he resembles his brothers Zeus and Poseidon, except that his hair falls down his forehead, and that the majesty of his appearance is dark and gloomy. His ordinary attributes are the key of Hades and Cerberus.
Sir William Smith, Dictionary Of Greek and Roman Biography and Mythology
"Hades, lord of the dead, was a gloomy god of few words. Mortals feared him so much that they did not dare mention his name, for they might attract his attention and he might send for them."
Ingri & Edgar D'Aulaire, Book Of Greek Myths
