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.
Nenia Dea Nenia Dea (Engl.: Goddess Nenia; rarely "Naenia") was an ancient funeral deity of Rome, who had a sanctuary outside of the Porta Viminalis. The cult of the Nenia is doubtlessly a very old one, but according to Georg Wissowa the location of Nenia's shrine "(sacellum)" outside of the center of early Rome indicates that she didn't belong to the earliest circle of Roman deities. In a different interpretation her shrine was located outside of the old city walls, because it had been custom for all gods connected to death or dying.
