Century Dictionary and Cyclopedia
    • n roc A fabulous bird of prey of monstrous size, famous in Arabian mythology, and corresponding to the Persian simurg. There is no certain basis of fact upon which the myth of the roc rests. The most colossal birds of which we have any knowledge are the dinornithic moas of New Zealand and the Madagascar æpyornithic elephant-birds. The largest known rapacious bird (the roc figures as a bird of prey) is the Harpagornis, which may have been able to kill a moa, though certainly not to fly away with one. The most plausible speculation bases the roc on the Æpyornis. See the quotation.
    • n roc A Middle English form of rock.
