OK, let's look at this picture. To the right of Matara-jin and Okina, it depicts Hata no Kawakatsu's relations: "enemy" to Tokoyo Kami (swallowtail larva, "suspected of being the same" as Eternity Larva, as the latter is "suspected of being enemy" to Okina), "close aide" to the Crown Prince (Miko), and "user" of the 66 noh masks (Kokoro).
Kawakatsu is embodied by the okina (old man) mask, which is equated with Matara-jin through "syncretism" 習合, and has the aspects of the god of
shuku (pariahs) and performing arts. Below the okina mask is the bodhisattva of North Star Myōken.
To the left of Okina are some other sources the author found that may have been incorporated into the "syncretism" of Matara-jin, including, from top to bottom:
- Amaterasu
- The bodhisattva Tara: "origin of the name [Matara]?"
- Mahakala: literally "Great Black", a tantric version of Shiva
- Daikokuten: Mahakala reinterpreted into an amicable folk god, one of Seven Lucky Gods
- Inaba: Japan's most popular harvest and prosperity god since early modern times; white foxes are his messengers.
The line from Kawakatsu to Inaba shows the latter to be the Hata clan's patron god.
