There was an article on Thomas Denny's windows at St Christopher's Church in Cheltenham in ArtServe magazine (Issue three, Autumn 2012). 

ArtServe member the Revd David New from Worcester, who helped enormously with the writing of the article, knows a great deal about Thomas Denny's work.

You can find some of David's poems inspired by Thomas Denny windows in the Poetry section of the site.

You can see photos of  the windows in greater detail on Thomas Denny's website.
Visit the The Church in Warden Hill website for more information about St Christopher's, the church featured in the magazine article, including the ten windows.
