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.
Disciplina In Roman mythology, Disciplina was a minor deity and the personification of discipline. The word "disciplina" itself, a Latin noun, is multi-faceted in meaning; it refers to education and training, self-control and determination, knowledge in a field of study, and an orderly way of life. The goddess embodied these qualities for her worshippers. She was commonly worshipped by imperial Roman soldiers, particularly those who lived along the borders of the Roman Empire; altars to her have been found in Great Britain and North Africa. The fort of Cilurnum along Hadrian's Wall was dedicated to the goddess Disciplina, as witnessed by an extant dedicatory inscription on a stone altar found in 1978. Her chief virtues were "frugalitas, severitas" and "fidelis"—frugality, sternness, and faithfulness. In worshiping Disciplina, a soldier became frugal in every way: with money, with energy and actions. The virtue of "severitas" was shown in his focused, determined, not easily dissuaded, and decisive behavior. He was faithful to his unit, his army, the officers and the Roman people.
