Newton's first reflecting telescope was completed in 1668 and is the earliest known functional reflecting telescope. The Newtonian telescope's simple design makes it very popular with amateur telescope makers. Newton's idea for a reflecting telescope was not new. Galileo Galilei and Giovanni Francesco Sagredo had discussed using a mirror as the image forming objective soon after the invention of the
Galilean Galilean Zealots and Judean Pharisees. During the Great Rebellion (66-70 CE) the Galileans and Idumeans were the most adamant fighters against Rome; they fought the Romans to the death when many Judeans were ready to accept peace terms. Unlike the Judeans and the Idumean, the Galileans survived until the 1930s in the village of Peki'in, after which the Jews were expelled to Hadera by the Arab riots. Until 500 years ago, Peki'in had a Jewish majority and in Medieval times, Galilean Jews had presence in many villages such as Kafr Yassif, Biriyya, Alma, and more. "Galileans" (or "Galilæans") were also
