The name Osiris originates from ancient Egyptian mythology and language. It is derived from the Egyptian hieroglyphic word "Usiré", which means "powerful" or "mighty". The name Osiris belongs to one of the most important deities in ancient Egyptian religion, the god of the afterlife, the dead, and resurrection.

Osiris was the mythological lord of the underworld, the judge of the dead, and the ruler of the realm of the deceased. According to ancient Egyptian beliefs, he was the first son of the earth god Geb and the sky goddess Nut. Osiris was considered the brother of Isis, Nephthys, and Set, and was married to Isis.

The stories and myths surrounding Osiris are found in various ancient Egyptian texts and hieroglyphic inscriptions, such as the Pyramid Texts, the Coffin Texts, and the Book of the Dead. These texts describe the legends of Osiris' birth, life, death, and resurrection, as well as his role in the afterlife.

One of the earliest recorded examples of the name Osiris dates back to the 5th Dynasty of ancient Egypt, around 2494-2345 BCE. The name appears in the Pyramid Texts, which were inscribed on the walls of the pyramids of Saqqara, and in the Coffin Texts, which were written on the interior of coffins and tombs.

Throughout history, several notable individuals have borne the name Osiris. One of the most famous was Osiris I, an ancient Egyptian pharaoh who ruled during the 5th Dynasty, around 2460-2453 BCE. Another was Osiris, the son of Ramses II, who lived during the 19th Dynasty, around 1279-1213 BCE.

In Greek mythology, the name Osiris was also used for the god Serapis, who was a syncretic deity that combined aspects of Osiris and the Greek god Apis. One of the most notable individuals with this name was Serapis of Tyre, a Greek philosopher and teacher who lived in the 3rd century CE.

Another historical figure named Osiris was a 4th-century Christian saint and martyr from Egypt. He was martyred during the persecution of Christians under the Roman emperor Diocletian in the early 4th century.

In the 17th century, there was an Ottoman Turkish poet and mystic named Osiris, who lived in the city of Bursa in modern-day Turkey. He was known for his devotional and mystical poetry, which often featured themes related to Sufism and Islamic spirituality.
