Selene is the moon goddess in ancient Greek mythology.
According to Hesiod's "Theology" [1], she is the daughter of the Titanic god Hyperion and Thea, the sister of the dawn goddess Aeos, and the twin sister of the sun god Helios. The traditional image of Selene in mythology is: wearing a brilliant crescent crown, wearing a robe or a veil; Sometimes, with wings and a golden halo, a lunar rover pulled by two divine horses (some say oxen, with horns symbolizing the new moon) gallops through the night sky, disappearing into Oshinas as day approaches. In classical mythology, Selene and his brother Helios drove through the sky in turn every day, forming the alternation of day and night. Luna corresponding to Roman mythology.

The etymology of Selene is unknown, but if the word comes from ancient Greek, it may be derived from σέλας (literal meaning: light).
Just as Helios is confused with Apollo, Selene is sometimes confused with Artemis in the late period of ancient Greece. According to Hesiod's "Divine Manual", Selene's mother is Tea, who is one of the Titans, and is called "the vast light" in Homer's epic, possibly the ancient goddess of light. In the late classical era, [2] Selene was also called Cynthia [3] while mixing with Artemis.

Selene played an important role in the witchcraft of ancient Greece. Ancient people believed that the roundness of the moon would have an impact on human life: a full moon would make all things flourish and grow, while a declining moon would hinder the development of all things. Therefore, a declining moon is beneficial for treating diseases or exorcising evil spirits. The residents of the Thessaly region also believe that witches will perform spells during lunar eclipses. Until the Hellenistic era, people still believed that Selene was the carrier of soul.
In ancient Greece, the festival commemorating Selene was the vernal equinox.

The love story between Selene and Endymion is very famous in Greek mythology. Endymion is a beautiful young man admired by Selene. He was granted eternal youth by the gods, but at the cost of eternal sleep in the cave of Mount Latmus in Karia. According to the myth of the region of Orea (a region in ancient Greece, roughly equivalent to today's Ilia), Selene gave birth to 50 daughters to Endymion, which is a reflection of the 50 weeks of a year in the ancient Greek calendar [4].
Apollonius recorded this myth in more detail [5]. Endymion was a mortal hunter or shepherd (according to Pausanias [6], Endymion was the king of Elea). His appearance is extremely beautiful, and Selene, fascinated by this amazing beauty, asked Zeus to let Endymion remain young forever. But Selene learned from Eos that it was impossible to ask God to grant eternal life to mortals, so this request became to let Endymion sleep forever, so that he would neither die nor leave her. Cicero also said that in this event, Selene took the initiative to ask Endymion to sleep. But in other versions, it was Endymion's own decision not to wake up. Endymion's Mount Latmus is very close to Miletus. Every night when Selene passed through the sky, he would visit Endymion in his sleep with a sad face. The daughters of Selene and Endymion are called Menae (Menae is an alias of Selene [2]).
Pan
In the myth, Pan sent a group of lambs to Selene in order to pay attention to her; It is also said that Pan disguised himself as a lamb in an attempt to seduce Selene. The yoke on Selene's ox cart (or wagon) was also sent by Pan. [7]
Zeus
In addition, Selene was once associated with Zeus and gave birth to a daughter Pandya [8]. Some data believe that Selene is also the mother of the Nemean lion [9] (while it is generally believed that its mother is Ekdena).
