Our Lady’s window
The first two images show Our Lady carrying a stem of lilies, the symbol of purity. Lilies have long been associated with Mary and are, perhaps, the most common Marian symbol. This particular lily is the Madonna Lily (Lilium Candidum) which is native to the Balkans and West Asia. In summer it produces fragrant white flowers which are yellow at the base. Also associated with Our Lady is the Lily of the Valley (Convallaria majalis), but that’s a different plant altogether.
In the image on the right is a monogram comprising the intertwined letters A and M which stand for “Ave Maria” (Hail Mary, in Latin). Unfortunately, the very bottom of the window, including the bottom half of the monogram, is partially blurred by protective glazing.
