The title lucina (from the Latin lux, lucis, "light") links both Juno and Diana to the light of the Moon, the cycles of which were used to track female fertility as well as measure the duration of a pregnancy. Priests of Juno called her by the epithet Juno Covella on the new moon.[1] The title might alternately have been derived from lucus ("grove") after a sacred grove of lotus trees on the Esquiline Hill associated with Juno, later the site of her temple.[3]
Juno Lucina was chief among a number of deities who influenced or guided every aspect of birth and child development, such as Vagitanus, who opened the newborn's mouth to cry, and Fabulinus, who enabled the child's first articulate speech. The collective di nixi were birth goddesses, and had an altar in the Campus Martius.
