Nurtia is a goddess from a mythology  that was later incorporated into which culture ?
Etruscan mythology Etruscan mythology comprises a set of stories, beliefs, and religious practices of the Etruscan civilization, originating in the 7th century BC from the preceding Iron Age Villanovan culture, with its influences in the mythology of ancient Greece and Phoenicia, and sharing similarities with concurrent Roman mythology. As the Etruscan civilization was assimilated into the Roman Republic in the 4th century BC, the Etruscan religion and mythology were partially incorporated into classical Roman culture, following the Roman tendency to absorb some of the local gods and customs of conquered lands.
Gaia (mythology) In Greek mythology, Gaia ( or from Ancient Greek Γαῖα , a poetical form of Γῆ "Gē", "land" or "earth"), also spelled Gaea, is the personification of the Earth and one of the Greek primordial deities. Gaia is the ancestral mother of all life: the primal Mother Earth goddess. She is the immediate parent of Uranus (the sky), from whose sexual union she bore the Titans (themselves parents of many of the Olympian gods) and the Giants, and of Pontus (the sea), from whose union she bore the primordial sea gods. Her equivalent in the Roman pantheon was Terra.
