• noun An ancient constellation and sign of the zodiac. The figure represents a winged woman in a robe holding a spike of grain in her left hand. One of the stars was called Vindemiatrix, or by the Greeks Protrygeter—that is, precursor of the vintage. At the time when the zodiac seems to have been formed, 2100 B.C., this star would first be seen at Babylon before sunrise about August 20th, or, since there is some evidence it was then brighter than it is now, perhaps a week earlier. This would seem too late for the vintage, so that perhaps this tradition is older than the zodiac. Virgo appears in the Egyptian zodiacs without wings, yet there seems no room to doubt that the figure was first meant for the winged Assyrian Astarte, especially as the sixth month in Accadian is called the “Errand of Istar.” The symbol of the zodiacal sign is ♍, where a resemblance to a wing may be seen. The constellation contains the white first-magnitude star Spica. See cut in next column.
