There are no true antelope native to the Americas. The pronghorn antelope of the Great Plains belongs to family Antilocapridae. The pronghorn is the fastest animal in North America running at speeds up to 54 miles per hour (90 kilometers per hour). Unlike the hollow horns of true antelope, the horns of a pronghorn are made up of a hairlike substance that grows around a bony core; the outer sheath is shed annually.
The endangered African Oryx (Oryx beisa) is also an antelope. The Mongolian Gazelle (Procapra gutturosa), sometimes classified as an antelope, can run with a speed of 80 km/h (50 mph).
The antelope's horn is prized for medicinal and magical powers in many places. In the Congo, it is thought to confine spirits. Christian iconography sometimes uses the antelope's two horns as a symbol of the two spiritual weapons that Christians possess: the Old Testament and New Testaments. Their ability to run swiftly has also led to their association with the wind, such as in the Rig Veda, as the steeds of the Maruts and the wind god Vaya.
