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

Michael Sokoloff's English preface to Caspar Levias' Hebrew language "Grammar of Galilean Aramaic" (1986) also sheds light on the controversy that began with Dalman.

More recently attempts to better understand the Galilean dialect vis a vis the New Testament have been taken up by Steve Caruso. Evidence on possible shortening or changing of Hebrew names into Galilean is limited. Ossuary inscriptions invariably show full Hebrew name forms. David Flusser suggested that the
