Gabriel the Iberian was a 10th-century Georgian monk belonging to the Iviron Monastery on Mount Athos. Born in the Kingdom of Iberia, he lived a life of extreme asceticism, often retreating to mountain caves during the summer to seek solitude. He was a contemporary of the monk John the Iberian and was known for his strict adherence to spiritual discipline, which included wearing garments made of animal hair and maintaining a vow of silence regarding worldly matters.
