Grigorios of Dekapolis was a 9th-century Byzantine monk recognized as a wonderworker. Born in Irenopolis, he was known for his extensive travels throughout the Byzantine world, including journeys to Ephesus, Rome, and Sicily. He is frequently referred to as the New Miracle-Worker due to his reputation for performing miracles. After living as a hermit and a monk, he eventually settled in Constantinople, where he died in 842. He is remembered as an advocate of the iconophile position during the era of Iconoclasm.
