Martin of Vertou was a sixth-century monk, hermit, and abbot who lived in the region near Nantes in Francia. Recognized for his learning and virtue, he served as an archdeacon under Bishop Felix of Nantes. He played a significant role as an evangelist in the local area, earning him the title of Apostle of the Herbauges. After years of ministry, he sought solitude in the wasteland near the Sèvre Nantaise, where his presence eventually led to the establishment of several religious communities.
