The stained-glass windows of Charles J. Connick will be the focus of six special events -- a series of lectures and tours that begins Sunday at Calvary Episcopal Church.

Sponsored by Pittsburgh History & Landmarks Foundation, which last year published Albert M. Tannler's excellent illustrated guide, "Charles J. Connick: His Education and His Windows In and Near Pittsburgh," the series will feature Tannler and others speaking about Connick's work.

His windows for Heinz Memorial Chapel and dozens of churches here and from Maine to California made Connick a leader in the movement away from the dark, pictorial windows of John LaFarge and Louis Comfort Tiffany and toward a return to the flat, medieval style. Pittsburgh has a great collection of Connick windows; this is a chance to see them and learn about them.

Here's the lineup:

Sunday: Keynote address, church tour and reception, 2:30-5:30 p.m., Calvary Episcopal Church, 315 Shady Ave., Shadyside. English historian Peter Cormack will present an illustrated talk, "Stained Glass of the Arts & Crafts Movement in Britain and America," at 3 p.m.; organist Alan Lewis will perform from 2:30-3 p.m. as people gather. Cormack will discuss the international significance of Connick's work. A tour of the church, where about 70 Connick windows were installed from 1922 to 1939, and a reception will follow. Suggested donation: $10 PHLF members, $20 nonmembers; free to students with ID.

June 21: Lecture and church tour, 2-4 p.m., First Baptist Church, 159 N. Bellefield Ave., Oakland.
