My last visit to the Congregational church was nearly twenty years ago. The fact that the interior had not deteriorated more is a blessing. Personally I like John La Farge’s stained glass better than Tiffany. The relationship between Tiffany and La Farge was tempestuous at best.
The Prayer Rug was the basis for the decoration. The idea was to avoid any idolatry, so geometric aesthetism was the solution. This is I believe the only complete work of both the stain glass and frescos by John La Farge anywhere.
James Yarnell, has written the definitive work on John La Farge.
