Hathor was a major goddess in ancient Egyptian religion who played a wide variety of roles, including sky deity, solar goddess, goddess of music and love, patroness of mining, and guide of the dead into the afterlife. She was considered the symbolic mother of the pharaohs through her mythological roles as wife of Ra and mother of Horus. More temples were dedicated to her than to any other Egyptian goddess.
Hathor's most common form in Egyptian art was a woman wearing a headdress of cow horns and a sun disk, often with a red or turquoise sheath dress. She could also be depicted as a cow bearing the sun disk between her horns, as a woman with a cow's head, as a lioness, a cobra, a domestic cat, or a sycamore tree. Her face sometimes appeared as a frontal human face with bovine ears on the capitals of temple columns, a style known as the Hathoric column.
Hathor's most prominent temple was at Dendera in Upper Egypt. It dates to at least the Fourth Dynasty, roughly 2613-2494 BC. The last version of the temple was built in the Ptolemaic and Roman Periods and is today one of the best-preserved Egyptian temples from that era.
The Festival of Drunkenness commemorated the return of the Eye of Ra and was celebrated on the twentieth day of the month of Thout. It involved drinking, dancing, and eating that represented the opposite of the sorrow, hunger, and thirst the Egyptians associated with death. Scholars believe celebrants aimed to reach an altered state of consciousness to interact with the divine realm.
Hathor was linked to trade goods and foreign lands including Nubia, Canaan, and the Sinai Peninsula. The Egyptians equated the patron goddess of Byblos, Baalat Gebal, with Hathor as early as the Old Kingdom. She held epithets such as "Lady of Mefkat" connected with turquoise and blue-green minerals, and the largest temple complex in the Sinai at Serabit el-Khadim was dedicated primarily to her as patroness of mining.
Hathor helped the spirits of deceased humans enter the Duat, the realm of the dead, and was closely associated with necropolises on the west bank of the Nile. Coffins and tombs were interpreted as her womb, from which the deceased would be reborn like the sun god. In the Third Intermediate Period, roughly 1070-664 BC, Egyptians began adding Hathor's name to that of deceased women, and this association continued into the Roman Period.
