EAGLE, in Astronomy, is a constellation of the northern hemisphere, having its right wing contiguous to the equinoctial. See AQUILA.

There are also three several stars, particularly denominated among the Arab astronomers, nasr, i. e. "eagle." The first, nasr sohail, the "eagle of Canopus," called also sitarch jemen, the star of Arabia Felix, over which it is supposed to preside; the second, nasr althair, the "flying eagle;" and the third, nasr alveke, the "resting eagle."

White Eagle, is a Polish order of knighthood, instituted in 1325 by Uladislau V. on marrying his son Casimir with a daughter of the great duke of Lithuania.

The knights of this order were distinguished by a gold chain, which they wore on the stomach, whereon hung a silver eagle crowned.

Black Eagle, was a like order, instituted in 1701 by the elector of Brandenburg, on his being crowned king of Prussia.

The knights of this order wear an orange-coloured ribbon, to which is suspended a black eagle.
