Mother Nature (sometimes known as Mother Earth or the Earth Mother) is a Greco-Roman personification of nature that focuses on the life-giving and nurturing aspects of nature by embodying it, in the form of the mother.
The word "nature" comes from the Latin word, "natura", meaning birth or character (see nature (innate)). In English, its first recorded use (in the sense of the entirety of the phenomena of the world) was in 1266. "Natura" and the personification of Mother Nature were widely popular in the Middle Ages. As a concept, seated between the properly divine and the human, it can be traced to Ancient Greece, though Earth (or "Eorthe" in the Old English period) may have been personified as a goddess. The Norse also had a goddess called Jord (or Erth).
The earliest written usage is in Mycenaean Greek: Ma-ka (transliterated as ma-ga), "Mother Gaia", written in Linear B syllabic script (13th or 12th century BC). In Greece, the pre-Socratic philosophers had "invented" nature when they abstracted the entirety of phenomena of the world as singular: physis, and this was inherited by Aristotle. Later medieval Christian thinkers did not see nature as inclusive of everything, but thought that she had been created by God; her place lay on earth, below the unchanging heavens and moon. Nature lay somewhere in the center, with agents above her (angels), and below her (demons and hell). For the medieval mind she was only a personification, not a goddess.
