In Sabine and ancient Roman religion and myth, Luna is the divine embodiment of the Moon. She is often presented as the female complement of the Sun, Sol, conceived of as a god. Luna is also sometimes represented as an aspect of the Roman triple goddess, along with Diana and either Proserpina or Hecate. Luna is not always a distinct goddess, but sometimes rather an epithet that specializes a goddess, since both Diana and Juno are identified as moon goddesses.

The vocabulary of ancient Roman religion was highly specialized. Its study affords important information about the religion, traditions and beliefs of the ancient Romans. This legacy is conspicuous in European cultural history in its influence on later juridical and religious vocabulary in Europe, particularly of the Christian Church. This glossary provides explanations of concepts as they were expressed in Latin pertaining to religious practices and beliefs, with links to articles on major topics such as priesthoods, forms of divination, and rituals.
