Protector deity

A tutelary (also tutelar) is a deity or spirit who is a guardian, patron, or protector of a particular place, geographic feature, person, lineage, nation, culture, or occupation.

One type of tutelary deity is the genius, 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.

Socrates spoke of hearing the voice of his personal spirit or daimonion:

You have often heard me speak of an oracle or sign which comes to me …. This sign I have had ever since I was a child. The sign is a voice which comes to me and always forbids me to do something which I am going to do, but never commands me to do anything, and this is what stands in the way of my being a politician.

The Greeks also thought deities guarded specific places: for instance, Athena was the patron goddess of the city of Athens.

Tutelary deities who guard and preserve a place or a person are fundamental to ancient Roman religion. The tutelary deity of a man was his Genius, or that of a woman her Juno. In the Imperial era, the Genius of the Emperor was a focus of Imperial cult. An emperor might also adopt a major deity as his personal patron or tutelary, as Augustus did Apollo. Precedents for claiming the personal protection of a deity were established in the Republican era, when for instance the Roman dictator Sulla advertised the goddess Victory as his tutelary by holding public games (ludi) in her honor.
