"The Idler in France"
Marguerite Gardiner
Of pyramidical shape, like the pharos of Alexandria, it was one hundred and thirty cubits high and twenty-three wide, with nine stories, diminishing as they approached the summit, and protected by scales of brass; they were pierced with numerous doors and were filled with soldiers, and on the upper platform there stood a catapult flanked by two ballistas.
"Salammbo"
Gustave Flaubert
The hills are huge groups, some single ones, glaring in sun above the rest, and others pyramidical.
