Knowest thou the time when the wild goats of the rock bring forth? The wild goats of Western Asia are of two kinds, the Capra segagrus, and the Asiatic ibex, or Capra Sinaitica. The latter is probably the animal hero intended, which is called yael sela, "the wild goat of the rocks," and was known to the Assyrians as ya-e-li.
It is an animal with large rough horns curving backwards, closely allied to the steinbock, or bouquetin, of the Swiss and Tyrolian Alps. It is very shy and wild, difficult of approach, and inhabiting only the most rocky and desolate tracts of Syria and Arabia.
