A tutelary (/ˈtjuːtəlɛri/; also tutelar) is a deity or a spirit who is a guardian, patron, or protector of a particular place, geographic feature, person, lineage, nation, culture, or occupation. The etymology of "tutelary" expresses the concept of safety and thus of guardianship.
In late Greek and Roman religion, one type of tutelary deity, the genius, functions as the personal deity or daimon of an individual from birth to death. Another form of personal tutelary spirit is the familiar spirit of European folklore.[1]
