Read it through once

We can not forget Florence--Naples--nor the foretaste of heaven that is in the delicious atmosphere of Greece--and surely not Athens and the broken temples of the Acropolis. Surely not venerable Rome--nor the green plain that compasses her round about, contrasting its brightness with her gray decay--nor the ruined arches that stand apart in the plain and clothe their looped and windowed raggedness with vines. We shall remember St. Peter's: not as one sees it when he walks the streets of Rome and fancies all her domes are just alike, but as he sees it leagues away, when every meaner edifice has faded out of sight and that one dome looms superbly up in the flush of sunset, full of dignity and grace, strongly outlined as a mountain.
