We have previously noted two plays about Matt Talbot. (See our link for "plays.") An analysis included in the book, Contemporary Irish Literature: Transforming Tradition (1998) by Christina Hunt Mahony can be found at http://www.amazon.com/gp/reader/0312219016/ref=sib_dp_ptu#reader-link.
In the search box to the left of your screen, type "Talbot's Box."
Then click each page link (p 149, 150, 151, 152).
Other commentaries on this play by Thomas Kilroy are available through a Google search.
