Sky deity

A sky deity is a god or goddess associated with the sky. These figures are a common feature in polytheistic religions, which are belief systems involving many different gods. Because the sky is vast and constantly changing, it often carries deep religious significance for many cultures. Many traditions view the sky as an "upper world" or a "celestial realm." This realm is often positioned as the opposite of the earth or a "netherworld." Gods who rule the underworld are sometimes called chthonic deities.

Sky deities are often categorized by the specific parts of the sky they oversee. Daytime sky deities are typically distinct from nighttime ones. In the study of folk literature, Stith Thompson’s Motif-Index separates "Sky-god" (A210) from "Star-god" (A250). Nighttime gods are usually known as night deities, while those in charge of stars are called star gods. Luminary deities are also included because the sun and moon are located in the sky. Some religions even feature a deity of the day that is separate from the god of the lit sky.

Many sky gods hold roles related to leadership and family structures. A masculine sky god is often the king of the gods and acts as a patriarch within a pantheon. These figures are collectively categorized as "sky father" deities. There is often a polarity, or a balance, between the sky and the earth. This is frequently expressed by pairing a sky father with an "earth mother" goddess. While less frequent, some traditions pair a sky mother with an earth father. A main sky goddess may serve as the queen of the gods. She might be an air or sky goddess herself, though she often has other primary functions.

In Greek mythology, the history of the sky follows a specific sequence of rulers. Uranus was the primordial sky god, meaning he was one of the first beings. He was ultimately succeeded by Zeus. Zeus ruled the celestial realm from the top of Mount Olympus. This created a clear division between different realms of existence. While Zeus ruled the sky, the chthonic deity Hades ruled the underworld. Meanwhile, the god Poseidon ruled the sea.

Different cultures across the globe have developed unique names and roles for these beings. In Africa, the Yoruba people believe in Olorun, the supreme deity of the sky and heaven. The Zulu people recognize Umvelinqangi as a sky god. In Asia, the Japanese Shinto tradition honors Amaterasu, the goddess of the sun and the universe. In Central Asia, the Turkic and Mongolic traditions include Tengri, a god of the sky. The Chinese tradition features several emperors, such as the Jade Emperor, who holds a central role in the celestial hierarchy.

In the Americas, sky deities reflect diverse ways of understanding nature. The Incan people worshipped Inti, the god of the Sun, and Mama Killa, the goddess of the Moon. The Lakota people recognize various spirits, such as the Morning Star spirit, Anpao wichapi. They also recognize the Cloud People, known as the Wi Mahpiya Oyate. In the Mayan tradition, Hunab Ku is recognized as a sky father. These varied beliefs show how different groups interpret the celestial world around them.

Sky deities often connect to broader concepts of power and the universe. In ancient Semitic religions, the god El was a supreme sky father. He was often paired with the fertility goddess Asherah. The Hebrew Bible notes that the 7th-century Judean king Josiah removed the statue of Asherah from the temple of Yahweh in Jerusalem. This historical shift contributed to the rise of Hebrew monotheism by the 7th century BCE. These stories demonstrate how the way people view the sky can change over long periods of history.
