Galilean moons century when other inner moons were discovered, and Marius' names became widely used. Galileo was able to develop a method of determining longitude based on the timing of the orbits of the Galilean moons. The times of the eclipses of the moons could be precisely calculated in advance, and compared with local observations on land or on ship to determine the local time and hence longitude. The main problem with the technique was that it was difficult to observe the Galilean moons through a telescope on a moving ship; a problem that Galileo tried to solve with the invention of
Galilean dialect and commented upon the Galilean Aramaic speech. Schöttgen's work, "Horae Ebraicae et Talmudicae", which studied the New Testament in the context of the Talmud, followed that of Lightfoot. Both scholars provided examples of differences between Galilean and Judean speech. The grammarian Gustaf Dalman identified "Galilean Aramaic," but he was doubted by Theodor Zahn. Porter (2000) notes that scholars have tended to be "vague" in describing exactly what a "Galilean dialect" entailed. Hoehner (1983) notes that the Talmud has one place with several amusing stories about Galilean dialect which indicate only a defective pronunciation of gutturals in the third and fourth
