Prompt
Create an image of Saint Irenaeus, a 2nd-century bishop, as a mature man with a gentle yet authoritative expression, dressed in traditional bishop attire, holding a book, likely a representation of his notable work "Against Heresies". He should be depicted in a realistic style, possibly with a background that subtly suggests his connection to Lugdunum (modern-day Lyon), where he served as bishop and wrote extensively. Incorporate elements that reflect his role as a defender of Christianity and his influence on the faith, such as a subtle cross or symbols representing the unity of the church. The overall mood should convey wisdom, resilience, and devotion.
