St. Sophia had disappeared. Strange to say (the result perhaps of the concussion of air occasioned by the blowing up of the city) huge, white thunder clouds lifted themselves up from the southern horizon, and gathered overhead; they were the first blots on the blue expanse that I had seen for months, and amidst this havoc and despair they inspired pleasure. The vault above became obscured, lightning flashed from the heavy masses, followed instantaneously by crashing thunder; then the big rain fell. The flames of the city bent beneath it; and the smoke and dust arising from the ruins was dissipated.
