The narrative recounts a saint's campaign to displace entrenched pagan worship at Tara, where he miraculously topples a great idol and its smaller images, yet the people call out for another shrine located in the western country. A strong companion in the saint's train, troubled when a member of the household joins the lament, resolves to journey westward to confront the western idol using a famed handstone, setting off a sequence of encounters with wizards, rival priests, and local customs. The tale mixes episodes of religious conflict, folklore, personal loyalty, and illustrated reconstructions to explore conversion, magic, and communal ritual.
