In the 1940s comics that first featured Dr. Fate, his parents were a Swedish archaeologist and his spiritualist wife. In a larger, pop culture sense, however, he was the child of Helena Blavatsky and Howard Carter.
Like all the early heroes, he distilled elements that were floating around in the culture already. Both archaeology and spiritualism had their roots in the mid-1800s. Archaeology grew out of the attempt to trace the history of Biblical events, and to establish just how much of the actual narratives could be confirmed by outside evidence.
Although most of us think of Pluto as the Roman equivalent of the Greek god Hades, it is one of the Greek god’s titles, usually given as Pluton, Wealthy. This referred both to the earth’s fertility and the mineral riches that could be mined from it.
Thou shalt find to the left of the House of Hades a spring,
And by the side thereof standing a white cypress.
To this spring approach not near.
But thou shalt find another, from the Lake of Memory
Cold water flowing forth, and there are guardians before it.
Say, ‘I am a child of Earth and starry Heaven;
But my race is of Heaven (alone). This ye know yourselves.
But I am parched with thirst and I perish. Give me quickly
The cold water flowing forth from the Lake of Memory.’
And of themselves they will give thee to drink of the holy spring-
And thereafter among the other heroes thou shalt have lordship.
