After this famous ride, Bellerophon seized what he considered a good opportunity and tried to ascend to the top of the broad summit of Mount Olympus which towered almost twice as high as the summit of Mount Helicon. But Mount Olympus was the abode of the gods and this presumptuous act so angered Jupiter that he sent an insect to torment the steed which reared backward and threw its rider to the earth. Being now quite accustomed to a rider, Pegasus was presented to Aurora, Goddess of the Dawn, whose duty it was to lift the curtain of night with her rosy tinted fingers and open the eastern gates for Apollo, the Sun-god. In art Aurora is often pictured as a spirited maiden in dazzling robes riding swiftly on the winged Pegasus, although she is also represented as rising out of the ocean in the east in a car drawn by four white horses. Perhaps she decided to employ the latter exclusively to usher in the dawn, for Pegasus was later transposed to the stars and never again permitted to stray earthward. His great dark sky square with a star on each corner is exceedingly easy to find especially during September when it is on the sky slope in the east, although if there is any difficulty in locating it, let the eye travel from Cassiopeia to the Segment of Perseus--which resembles a rod bent in the middle and swayed by the weight of this big chained Square. The Square rises and sets in a tilted fashion with its corner star, Scheat, on the horse's knee, almost above Algenib, which lies on his wing. [Figure 38] "as if by art at equal distance placed." This causes the Square to resemble a distorted diamond-shaped figure when seen in the east or west but when the figure travels along the south about nine o'clock during the latter part of October or the first of November, its sides are horizontal and vertical. The Winged Horse first makes his appearance in the northeast near midnight in the middle of June but is better seen in the east between nine and ten o'clock a little later in the summer. Any time during the Autumn he may be seen flying inverted across the dome of the heavens and by November is high in the west. Evening after evening his silvery wings fly lower and lower; the star Enif flutters as it nears the thickened atmosphere about the horizon and Andromeda probably trembles as he draws her near Cetus, head downward through the western sky. [Figure 39: The Winged Horse flies head downward in the west.] "The head of Andromeda is setting and against her is brought by the Misty South the mighty terror, Cetus, but over in the North Cepheus with his mighty hand upraised warns him back." --_Aratus._
