DIKE, or Dyk, also denotes a work of stone, timber, or fascines, raised to oppose the entrance or passage of the waters of the sea, a river, lake, or the like.—The word comes from the Flemish dyk, or diik, a heap of earth to bound or stem the water. Junius and Menage take the Flemish to have borrowed their word from the Greek τὸν ὄρος, wall. Guichard derives it from the Hebrew daghah.
Dikes are usually elevations of earth, with hurdles of stakes, stones, and other matters.
The dike of Rochel is made with vessels fastened to the bottom. The dikes of Holland are frequently broke through, and drown large tracts of land.
