Sirona
Dirona (Sirona) In Celtic mythology, a mother goddess who appears to be identical with the goddess known elsewhere as Divona. She is depicted with a dog on her lap, a diadem (implying high status), three eggs (a fertility symbol), and a snake wrapped around her arm. The ancient Roman writers associated her with the consort of their god Mercury.
