Epona's name derives from the gaulish word for „horse“ (epos). She's the goddess of horses and protector of their well-being, health, and so on.
Yet Epona is also regarded as a mother goddess, goddess of wellfare, fertility, and health in general. Her status within the Celtic pantheon must have been quite prominent. Ancient innoscriptions often add the noscript „Rigani“ to her name – which means „queen“.
