Ia of Persia was a Christian martyr who lived during the 4th century. Originally from the city of Visada, she was captured during the invasion of the Roman Empire by the Persian King Shapur II in 362. Among the thousands of captives taken to Khuzestan, she was handed over to Zoroastrian priests. Despite their efforts to force her to renounce her faith, she remained steadfast, eventually facing a series of brutal tortures before her death.
