Fertility deity in the context of "Hierodule"

Sacred prostitution, temple prostitution, cult prostitution, and religious prostitution are purported rites consisting of paid intercourse performed in the context of religious worship, possibly as a form of fertility rite or divine marriage (hieros gamos). Scholars prefer the terms "sacred sex" or "sacred sexual rites" in cases where payment for services is not involved.

The historicity of literal sacred prostitution, particularly in some places and periods, is a controversial topic within the academic world. Historically mainstream historiography has considered it a probable reality, based on the abundance of ancient sources and chroniclers detailing its practices, although it has proved harder to differentiate between true prostitution and sacred sex without remuneration. Beginning in the late 20th century, a number of scholars have challenged the veracity of sacred prostitution as a concept, suggesting that the claims are based on mistranslations, misunderstandings or outright inventions of ancient authors. Authors have also interpreted evidence as secular prostitution administered in the temple under the patronage of fertility deities, not as an act of religious worship by itself.

In ancient Roman religion, Ops, Opes or Opis (Latin: "Plenty") was a fertility deity and earth goddess of Sabine origin. Her equivalent in Greek mythology was Rhea.

Earth religion or nature worship is a system of religion based on the veneration of natural phenomena. It covers any religion that worships the earth, nature, or fertility deity, such as the various forms of goddess worship or matriarchal religion. Some find a connection between earth-worship and the Gaia hypothesis. Earth religions are also formulated to allow one to utilize the knowledge of preserving the earth.
