Euthalia of Sicily was a third-century Christian virgin and martyr who lived in Leontini. Following the miraculous healing and subsequent conversion of her mother, Eutropia, Euthalia embraced the Christian faith. This decision caused a deep rift within her family, specifically with her brother, who demanded that they renounce their new beliefs. Despite facing constant threats of violence, Euthalia refused to abandon her convictions and was eventually executed by beheading at the hands of her own brother.
