What does Oriana mean?
Etymology is disputed: commonly linked to Latin 'aurum' (gold), giving 'golden', but equally attributed to Latin 'oriri' / 'oriens' (to rise, dawn), giving 'dawn' or 'sunrise' — often glossed 'golden dawn'. A possible Iberian/Basque origin is also proposed. Flagged as uncertain; the gold reading is one of several.
What does Vesta mean?
Roman goddess of the hearth and its sacred, ever-burning fire, tended by the Vestal Virgins; the Roman counterpart of Greek Hestia. The fire link is the perpetual flame central to her cult.
