"The Beatitudes", designed by Frederick Wilson and fabricated by the Tiffany Glass and Decorating Company is a tour de force of art glass beauty. The 18’ diameter rose window from 1894 is five layers thick and abounds with sculpted drapery glass.

Femenella’s conservation of this window involved documentation, cleaning, repair of broken glass, replacement of damaged lead, and the installation of the completed window into an isothermal protective-glazing setting.
