Here's what we know:
* Ancient Egyptian Symbolism: The ankh symbolized life, eternal life, and the breath of life. It was often depicted in Egyptian art and was associated with gods like Osiris and Anubis.
* Modern Interpretations: In modern times, the ankh has been adopted by various spiritual and occult groups. Some people believe it has protective properties, but this is based on personal belief and cultural appropriation rather than historical fact.
* No Scientific or Archaeological Evidence: There's no evidence from ancient Egyptian texts or artifacts that suggests the ankh was used for warding off evil.
Ultimately, the belief that an ankh wards off evil is a modern interpretation with no basis in ancient Egyptian practices. If you are interested in the symbol's significance, it's best to approach it from a historical and cultural perspective rather than expecting it to have magical powers.
