Eagle. In astronomy, it is the name of one of the constellations in the northern hemisphere. Its right wing touches the equinoctial line; its left wing is next to the snake's head. Its beak is separated from the rest of the body by the circle that runs from Cancer to Capricorn.
The Eagle and Antinous are usually considered part of the same constellation. See Constellation.
In his catalogue, Ptolemy only counted fifteen stars in the constellation of the Eagle and Antinous. Tycho-Brahe counted seventeen stars: The British Catalogue counted seventy stars. Hevelius gave the longitudes, latitudes, sizes, etc, of the stars that were named by the first two authors. One can see the British catalogue's calculations concerning this constellation in Flamsteed's Historia Coelestis .
