Latin Jupiter and Greek Zeus. The names of these two gods, it turns out, trace back to one and the same word — one of the most famous findings in Müller’s comparative mythology. From this discovery, he pushed forward into a much larger theory.
Jupiter = Zeus = “Sky Father”
Vedic Sanskrit has a god called Dyaus Pitar (“sky father”). Müller points out:
Dyaus is most frequently called pitar or father, so much so that Dyaushpitar in the Veda becomes almost as much one word as Jupiter in Latin.
Dyaus Pitar (Sanskrit) = Ju-piter → Jupiter (Latin) = Zeus Pater (Greek) — by the sound correspondences, Müller concluded, all of these trace back to one shared original expression for “sky father.” This finding has held up, and remains widely accepted in comparative mythology and comparative religion to this day.
From there to a “disease of language”
Using this discovery as a springboard, Müller advances a much larger claim. Ancient peoples, he argues, originally spoke of nature — the sun, the sky, the dawn — through simple metaphor: something like “the sun chases the dawn.” But as generations passed, the meaning of the original metaphor was forgotten, and the phrase itself took on a life of its own, passed down as a story of a sun-god chasing a dawn-goddess. Müller describes this process, explicitly, as a disease.
There is as much mythology in our use of the word Nothing as in the most absurd portions of the mythological phraseology of India, Greece, and Rome: and if we ascribe the former to a disease of language…
Elsewhere, in Lecture X, he argues that mythology and religion are two different things, and that mythology is what results when “an affection or disorder of language” eats into what was originally a healthy religious intuition. When people say “the sun is god,” on his account, they have mistakenly applied the predicate “god” to the sun itself — and it’s this very misuse, he argues, that is the origin of idolatry. Language’s proper role is to put into words the impressions received by the senses and the concepts of a rational mind; when metaphor breaks free of that role and takes on a life of its own, that, for Müller, is the disease.
Where the overreach was
The trouble is that Müller tried to apply this framework to most of Greek mythology. In Lecture XI, “Myths of the Dawn,” he sets out to re-explain the names of Hermes and many other gods as forgotten metaphors for the sun, the dawn, or the storm. But this generalization didn’t hold. The British anthropologist Andrew Lang later fired back with a book bearing the exact same title as Müller’s own Lecture XII, Modern Mythology (1897) — and pointed out that structurally similar myths, unconnected to sun or dawn imagery at all, turn up across countless cultures the era called “primitive.” Lang and his fellow anthropologists argued that what produces myth isn’t the misuse of language so much as a far more universal working of the human mind itself. Where Müller located the ancient mind’s leap from “the sun is god” in language, Lang and the anthropologists located it in the mind.
Summary
| Point | Content |
|---|---|
| The solid finding | Dyaus Pitar = Jupiter = Zeus, all tracing to one shared ancestral expression |
| The core theory | Myth is a “disease of language” — forgotten metaphors for nature, personified |
| Where it overreached | Trying to explain most of Greek mythology with this framework alone |
| The later rebuttal | Andrew Lang, Modern Mythology (1897), from an anthropological angle |
In a nutshell — the discovery that Jupiter and Zeus are the same word remains an achievement that hasn’t dated. But the generalization built on top of it — reducing the origin of myth itself entirely to a problem of language — was corrected by the next generation of scholars.
