Title: Horae
Content:  The number of Horae varied according to different sources, but was most commonly three: either the trio of Thallo, Auxo and Carpo (goddesses of the order of nature) or Eunomia (goddess of good order and lawful conduct) and her sisters Dike (goddess of Justice) and Eirene (goddess of Peace).
Title: Horae
Content:  In Greek mythology the Horae or Horai  or Hours (Ὧραι, Hōrai,, "Seasons") were the goddesses of the seasons and the natural portions of time.
Title: Horae
Content: in one variant emphasizing their fruitful aspect, Thallo, Auxo, and Carpo—the goddesses of the three seasons the Greeks recognized: spring, summer and autumn—were worshipped primarily amongst rural farmers throughout Greece; ; in the other variant, emphasizing the "right order" aspect of the Horai, Hesiod says that Zeus wedded "bright Themis" who bore Diké, Eunomia, and Eirene, who were law-and-order goddesses that maintained the stability of society; they were worshipped primarily in the cities of Athens, Argos and Olympia. The earliest written mention of Horai is in the Iliad where they appear as keepers of Zeus's cloud gates. "Hardly any traces of that function are found in the subsequent tradition," Karl Galinsky remarked in passing. They were daughters of Zeus and Themis, half-sisters to the Moirai. The Horai are mentioned in two aspects in Hesiod and the Homeric Hymns:

Of the first, more familiar, triad associated with Aphrodite and Zeus is their origins as emblems of times of life, growth (and the classical three seasons of year): At Athens, two Horae: Thallo (the Hora of spring) and Carpo (the Hora of autumn), also appear in rites of Attica noted by Pausanias in the 2nd century AD. Thallo, Auxo and Carpo are often accompanied by Chione, a daughter of Boreas (the god/ personification of the North Wind) and Orithyia/ Oreithyia (originally a mortal princess, who was later deified as a goddess of cold mountain winds), and the goddess/personification of snow and winter. Along with Chione, Thallo, Auxo and Carpo were a part of the entourage of the goddess of the turn of the seasons, Persephone.
Title: Horae
Content:  Horae were originally the personifications of nature in its different seasonal aspects, but in later times they were regarded as goddesses of order in general and natural justice. "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: "Hora means 'the correct moment'." Traditionally, they guarded the gates of Olympus, promoted the fertility of the earth, and rallied the stars and constellations. The course of the seasons was also symbolically described as the dance of the Horae, and they were accordingly given the attributes of spring flowers, fragrance and graceful freshness. For example, in Hesiod's Works and Days, the fair-haired Horai, together with the Charites and Peitho crown Pandora—she of "all gifts"—with garlands of flowers. Similarly Aphrodite, emerging from the sea and coming ashore at Cyprus, is dressed and adorned by the Horai, and, according to a surviving fragment of the epic Cypria, Aphrodite wore clothing made for her by the Charites and Horai, dyed with spring flowers, such as the Horai themselves wear.
Title: Horae
Content:  In Argos, two Horae, rather than three, were recognised presumably winter and summer: Auxesia (possibly another name for Auxo) and Damia (possibly another name for Carpo). In late euhemerist interpretations, they were seen as Cretan maidens who were worshipped as goddesses after they had been wrongfully stoned to death.

Title: Horae
Content:  Nonnus in his Dionysiaca mentions a distinct set of four Horae, the daughters of Helios. Quintus Smyrnaeus also attributes the Horae as the daughters of Helios and Selene, and describes them as the four handmaidens of Hera. The seasons were personified by the ancients, the Greeks represented them generally as women but on some antique monuments they are depicted as winged children with attributes peculiar to each season. The Greek words for the four seasons of year:
Title: Hathor
Content:  Hathor ( "House of Horus", Hathōr, ) was a major goddess in ancient Egyptian religion who played a wide variety of roles. As a sky deity, she was the mother or consort of the sky god Horus and the sun god Ra, both of whom were connected with kingship, and thus she was the symbolic mother of their earthly representatives, the pharaohs. She was one of several goddesses who acted as the Eye of Ra, Ra's feminine counterpart, and in this form she had a vengeful aspect that protected him from his enemies. Her beneficent side represented music, dance, joy, love, sexuality, and maternal care, and she acted as the consort of several male deities and the mother of their sons. These two aspects of the
