Pegasus with upright constellation :
In mythology we have "Pegasus," the winged horse as depicted on some series of
Uruguay, and the 1930 issue of Italy (50c.). In the Uruguayan issue an astronomical
contribution is represented, for in the upper left and lower right corners of the stamps can
be found the constellation of Pegasus, which is unique in that it is inverted when seen
from the northern hemisphere and upright when seen from the southern. It is shown
upright, as it appears in the Uruguayan heavens.
"Pegasus" was the winged horse of Grecian mythology, that sprang from the blood of
Medusa when the latter was slain by Perseus. As soon as it was created it flew to the
abode of the gods. Here Zeus took it, harnessed it to his chariot, and drove furiously
through the clouds, flashes of lightning darting out of the horses' hoofs.
