Horae

"They bring and bestow ripeness, they come and go in accordance with the firm law of the periodicities of nature and of life", Karl Kerenyi observed, adding "Hora means 'the correct moment'.

"[2] Traditionally, they guarded the gates of Olympus, promoted the fertility of the earth, and rallied the stars and constellations.

Nicolas Poussin has represented the four seasons by subjects drawn from the Bible: Spring is portrayed by Adam and Eve in paradise: Summer, by Ruth gleaning: Autumn, by Joshua and Caleb bearing grapes from the promised land; and Winter, by the deluge.

In more modern representations the seasons are often surrounding Apollo: Spring, as Flora, crowned with flowers, and in a shaded green drapery over a white robe: Summer, standing under the lion in the zodiac, with a gold-coloured drapery over a white gauze vestment, the edges of which are tinged by the yellow rays of the sun, holding a sickle, having near her a wheat-sheaf; Autumn, as a Bacchante, in a violet-coloured garment, pressing grapes with one band into a golden cup, which she holds in the other; and Winter as an aged person, placed in the shade at a great distance from the god.

[21][22] Finally, a quite separate suite of Horae personified the twelve hours (originally only ten), as tutelary goddesses of the times of day.
