What is the name of the protective amulet worn by boys?

The protective amulet worn by boys in ancient Rome is called a bulla. The bulla was a locket-like charm that often contained a small piece of leather or metal inscribed with protective spells or symbols that were believed to ward off evil spirits and ensure the well-being of the child. Typically worn by boys from birth until they reached puberty, the bulla was an important part of a child's attire, serving both a practical and ceremonial function.

The stola, on the other hand, was a garment worn by women, specifically freeborn Roman women, as a symbol of their status. The laurel refers to the laurel wreath, which was a symbol of victory and honor, typically associated with triumphs and achievements rather than everyday life or protection. The tunica was a type of clothing that both men and women wore, similar to a tunic, but it is not specifically an amulet or protective item. Hence, the bulla stands out as the correct answer due to its unique role in Roman culture as a protective symbol for boys.
