Connor Newman thinks it unlikely that these two stones are actually the stones the Dindshenchas called Blocc and Bluigne, nor are these two graveyard stones in their original positions. He writes, "In a thinly disguised sexual metaphor, suggesting at the same time both intercourse and birth, it is related that Blocc and Bluigne, though normally so close together that one could barely fit one's hand sideways berween them, parted only before the rightful king, who passed berween them and thence to the Lia Fail, which cried out against his chariot axle."
