Abraham, the "father of the faithful" was further advanced in this sublime science [astronomy] than the entire Egyptian nation. He taught astronomy in the King's Court at Egypt. He had a telescope which far exceeded those of the Ross and Lick observatories, and infallible instrument, known as the Urim and Thummim; by it he read the round of the starry worlds, through distances far beyond the scope of the telescope, upward to that imponderable orb known as Kolob in the Book of Abraham, in the vicinity of the resident of the eternal God. No media intercepted his view of those mighty orbs, or produced by the laws of refraction, the slightest exception of the visual organs.
