Eridanus

Eridanus ĭrĭd´ənəs [key], large southern constellation stretching SW from Orion for about 60°. Because of its long, winding shape it was identified with a river by many ancient civilizations e.g., the Egyptians called it the Nile and the Babylonians called it the Euphrates. The brightest star in the constellation, Achernar , marks the southern end of the river. Eridanus reaches its highest point in the evening sky in December.
