The ancient Romans used magic in everyday life; even to kill them.
According to William Smith's A Dictionary of Greek and Roman Antiquities, people would regularly consult with magical professionals. Two examples are augurs and astrologers.
Augurs were trained to read signs in the natural world, like rock formations and wind directions. Necromancy was a large part of that, too. These interpretations greenlit construction projects, marriages, as well as major political decisions.
Astrologers were mathematicians and mapmakers, too. Each class hired them to make predictions for newborns. Various cults used them to announce start dates for a deity's festival. The state used them to plan for events. The military used them to plan their campaigns.
Despite the regular use of supernatural pleading, the use of "witchcraft" was strictly forbidden. In The Twelve Tables, a person faced the death penalty if they hired a witch to cast spells on someone, or cast the spell themself. This led to big business for amulets and spells of protection.
Accusations of witchcraft were used to keep magical and intellectual professionals from becoming too influential. Banishment and murder was regularly used by the powerful to distract from negative public opinion. The murder of Hypatia is a perfect example of this. People with information become a scapegoat for tyranny, even if they're an integral and respected part of that society.
