Who is James Joyce from The Power of Myth and what is their importance?

James Joyce was the author of "Ulysses" and "Finnegan's Wake." Among Campbell's previous works is "A Skeleton Key to Finnegan's Wake" which he writes with Henry Morton Robinson. Campbell quotes Joyce's development of the theme of compassion in his hero Stephen Dedalus. Campbell claims that St. Paul's Epistle to the Romans contains sentences about God's mercy that epitomize what Joyce has in mind in "Finnegan's Wake."
