Its source is Diviana, a Latin name meaning "Goddess."
This was one of the names of the ancient Roman moon goddess, equivalent to the Greek goddess Artemis. She was also goddess of the hunt and of chastity. Like most deities, she was called by several names, including Cynthia and Delia.
The Latinate form of this name, Diana, was borne by the late Princess of Wales. The outpouring of affectionate grief that marked her passing could find further expression in the naming of baby Dianas well into the new century.
