such as the Navigium Isidis, as well as initiation ceremonies resembling those of other Greco-Roman mystery cults. Some of her devotees said she encompassed all feminine divine powers in the world. The worship of Isis was ended by the rise of Christianity in the fourth through sixth centuries CE. Her worship may have influenced Christian beliefs and practices such as the veneration of Mary, but the evidence for this influence is ambiguous and often controversial. Isis continues to appear in Western culture, particularly in esotericism and modern Paganism, often as a personification of nature or the feminine aspect of divinity. In Egypt and Nubia Name and origins Whereas some Egyptian deities appeared in the late Predynastic Period (before c. 3100 BCE), neither Isis nor her husband Osiris were mentioned by name before the Fifth Dynasty (c. 2494–2345 BCE). An inscription that may refer to Isis dates to the reign of Nyuserre Ini during that period, and she appears prominently in the Pyramid Texts, which began to be written down at the end of the dynasty and whose content may have developed much earlier. Several passages in the Pyramid Texts link Isis with the region of the Nile Delta near Behbeit el-Hagar and Sebennytos, and her cult may have originated there. Many scholars have focused on Isis's name in trying to determine her origins. Her Egyptian name was written as () and was pronounced , which became () in the Coptic form of Egyptian, in the Meroitic language of Nubia, and , on which her modern name is based, in Greek. The hieroglyphic writing of her name incorporates the sign for a throne, which Isis also wears on her head as a sign of her identity. The symbol serves as a phonogram, spelling the st sounds in her name, but it may have also represented a link with actual thrones. The Egyptian term for a throne was also st and may have shared a common etymology with Isis's name. Therefore, the Egyptologist Kurt Sethe suggested she was originally a personification of thrones. Henri Frankfort agreed, believing that the throne was considered the king's mother, and thus a goddess, because of its power to make a man into a king. Other scholars, such as Jürgen Osing and Klaus P. Kuhlmann, have disputed this interpretation, because of dissimilarities between Isis's name and the word for a throne or a lack of evidence that
