Lady Lêta
"You can gather the identity of Leto and Hera from the fact that we call Artemis daughter of Leto (do we not?), but also give her the name of Eileithyia. So Hera and Leto are two names for one goddess."
The Temple of Hyacinthus worships Lady Lêta - a synchronization of Hera, Goddess of Marriage, and Leto, Goddess of Motherhood. We worship Lady Lêta as Goddess Queen of all domains under Hera and Leto, including childbirth, marriage, modesty, motherhood, women, and the stars of heaven.
In this, The Temple of Hyacinthus views Lord Apollo as a singleton - absorbing Lady Artemis and her domains into the Italic Primordial Deity, Diana Nemorensis.
