Note 391 — Chapter XV · FLOATING DOWN THE TIGRIS ON A KELEK

“Many other works of Semiramis,” writes Strabo, “besides those of Babylon, are extant in almost every part of this continent, as, for example, earth-works which are called mounds of Semiramis, walls and fortresses, aqueducts and cisterns for water, stair-like roads over mountains, canals communicating with rivers and lakes; roads and bridges.” Geography, Bk. XVI, Chap. II.
