2013 is the centenary of Princeton University’s Graduate College. An exhibition at the Seeley G. Mudd Manuscript Library highlights the College’s history: http://blogs.princeton.edu/mudd/2013/09/building-the-house-of-knowledge-the-graduate-college-centennial/
Back in Graphic Arts, Elizabeth and Perry Morgan, Class of 1946, generously donated a large, glass lantern slide of the Seven Liberal Arts window in Procter Hall, the College dining hall. Designed by William and Annie Lee Willet of Philadelphia, the stained glass window rises forty feet in height. The center row of images depicts the Seven Liberal Arts. The first four, the quadrivium, are arithmetic, geometry, music, and astronomy. The other three, the trivium, being grammar, rhetoric, and logic.
At the bottom is an inscription: Nec vocemini magistri quia magister vester unus est christus,” or “And be ye not called master, for one is your master, even Christ.”
William Willet (1869-1921) and Anne Lee Willet (1867-1943) collaborated on mural and stained glass designs from their studio in Pittsburgh and then, Philadelphia. The Willets incorporated in 1909, only a few years before their work at Procter Hall. At William’s death, Anne Lee took over the business, which still continues today.
