Source Verification: Diana
Every claim below is either what a named ancient source attests, in its own line or section, or a point where the sources themselves disagree.
What the Sources Attest
Is Diana the same goddess as Artemis?
Romans identified Diana with Artemis and inherited most of her mythology - the virgin huntress, the bow, the punishment of trespassers - but Diana carried two distinctly Roman cults Artemis never had: a federal Aventine temple shared across the Latin League, and the strange priest-combat rite at Lake Nemi.
Source: Livy, Ab Urbe Condita 1.45
Why was Diana's Aventine temple important to the Roman state?
It was built to belong to Rome's whole population rather than one class, and it also served as a shared shrine for the Latin League, the alliance of Latin cities around Rome - member cities sent representatives to worship there as a public sign of their common identity and standing with Rome.

What was the Rex Nemorensis at Lake Nemi?
The Rex Nemorensis, "King of the Wood," was the title of Diana's priest at her sacred grove by Lake Nemi. A runaway slave who broke a branch from a specific tree in the grove earned the right to fight the current priest for the position, and if he won, he took over as priest until his own eventual challenger arrived - a violent, hereditary-free succession with no clear parallel elsewhere in Roman religion.
Source: Ovid, Fasti 3.263-272
Why is the Nemi priesthood considered so unusual?
Almost every other Roman priesthood was inherited, elected, or appointed through ordinary political and religious channels. The Nemi rite instead let a runaway slave seize the office by killing the man who held it, a practice ancient authors themselves treated as an old survival they no longer fully understood rather than an institution they could explain.
Source: Ovid, Fasti 3.263-272
Does Diana have a role in Roman childbirth customs?
Yes - alongside her hunting and lunar associations, Diana was invoked by Roman women in childbirth, a domain she shares with Artemis in the Greek tradition through their common association with Eileithyia-like protective functions over women's transitions, even though the specific Roman prayers and rites differ from Greek practice.
Source: Virgil, Aeneid 11.532-538
Was Diana ever addressed by Juno's name?
Yes, in one specific cult role. Catullus's hymn to Diana calls her "Juno Lucina" among a string of titles invoked by women in labor, alongside "Trivia" and "Luna" - a case of two otherwise separate goddesses sharing one title for the same narrow function, protecting childbirth, rather than any wider merging of Diana and Juno.

Where Accounts Differ
- why the Nemi succession worked by combat
- Ancient sources themselves do not explain why the Rex Nemorensis succession worked by combat; it is recorded as an old practice rather than one with a stated rationale.
