n. (context biblical English) An unidentified large animal with horns, possibly the addax, mentioned in the Bible (Deuteronomy 14:5) as one of the animals permitted for food.

The pygarg (//) is an animal mentioned in the Bible in Deuteronomy 14:5 as one of the animals permitted for food. The Septuagint translates the Hebrew as in Koiné Greek ("white-rumped", from "buttocks" and "white"), and the King James Version takes from there its term pygarg.

Henry Baker Tristram (1867) proposed that the pygarg was the Saharan antelope addax and described it as "a large animal, over 3½ feet high at the shoulder, and, with its gently-twisted horns, 2½ feet long. Its colour is pure white, with the exception of a short black mane, and a tinge of tawny on the shoulders and back".

Outside the biblical use, the term was also applied to the Siberian roe deer in the 18th century, whose specific name is in scientific Latin.
