The figure in the left panel of the window is St Paul preaching in Athens, traditionally depicted as being in the middle of Mars Hill.  This references Acts Ch17 v16-33, the legend at the bottom of the figure ".. in Him we live and move and have our being .." is found at v28.

The monogram of W S D at the bottom of the panel is repeated on the right hand panel.
