Read it through once

We descended and entered. Within the church, long rows of fluted columns, like huge monuments, divided the building into broad aisles, and on the figured pavement fell many a soft blush from the painted windows above. I knew the church was very large, but I could not fully appreciate its great size until I noticed that the men standing far down by the altar looked like boys, and seemed to glide, rather than walk. We loitered about gazing aloft at the monster windows all aglow with brilliantly colored scenes in the lives of the Saviour and his followers. Some of these pictures are mosaics, and so artistically are their thousand particles of tinted glass or stone put together that the work has all the smoothness and finish of a painting. We counted sixty panes of glass in one window, and each pane was adorned with one of these master achievements of genius and patience.
