Horae , (Gr. Lat. Horoe, hours), in classical mythology, the goddesses of the order of nature. In Homer they are the ministers of Zeus, guardians of the gates of Otympus, and rulers of the clouds and weather. In Hesiod they are the daughters of Zeus and Themis (Justice), who provide not only the fruits in their season, but give to a state good laws, justice, and peace. They are usually mentioned in connection with the graces and the nymphs as attendants on the Olympian divinities, adorned with wreaths of flowers, and bringing blessings to men. Their number was indefinite; in Athens two only were worshipped, Thallo and Carpo, the Horae of spring and of the harvest season. On works of art they appear as blooming maidens, carrying the products of the seasons. The Hora of spring, the Chloris of the Greeks and Flora of the Romans, is especially celebrated in sculptures as the attendant of Venus rising from the sea, and of Proserpine on her ascent from the lower world.
