What supports it

2 points in its favour

  1. The name is the same, and Roman writers themselves described the cult as Persian.
  2. Mithra is a Zoroastrian yazata of long standing, so there is a real figure for the name to have come from rather than a reconstructed one.

What limits it

4 points that limit it

  1. Continuity of a name is not continuity of a cult. The Roman Mithras carries a new and distinctive imagery, and how much of the practice is continuous with Persian worship is exactly what remains debated.
  2. The tauroctony — the bull-slaying scene at the centre of every mithraeum — has no Iranian parallel anyone has established.
  3. Almost no Mithraic text survives. The argument is carried by iconography, which is why it has been running for a century and a half without resolving.
  4. This is a connection between two traditions, not between two deities: nothing here claims that a Roman initiate and a Zoroastrian priest worshipped the same god.

What this means

Documented influence. A transmission argued from evidence. Not shared symbols, and not a short path through a database. It does not imply shared symbols as evidence, or a short path through a database.

It is not a path through the records. This site can always find a chain of statements between two well-known subjects, and that chain is a fact about this database rather than an argument about history — which is why a computed path is a different type, a different file and a different page from this one.

It is not a verdict either. The limits above are the same size as the support because they are the same kind of thing: reasons, of which some point one way.
