Daniel 8:5

5. This he-goat was the Grecian empire impersonated in Alexander the Great (Daniel 8:21), as the Babylonian in Nebuchadnezzar (Daniel 2:38). The marvelous rapidity of Alexander’s conquests is well pictured by the goat which seemed to rush over the ground without touching it. (Compare the four-winged leopard, Daniel 7:6.) The Grecian empire is symbolized as a goat with one notable or conspicuous horn, because it rose and reached its culmination in Alexander, who in a very few years conquered the entire world, and almost literally took possession of the face of the whole earth. The Arabic designation of Alexander as the “two horned” has no reference to this passage (Prince), but probably grew out of the Egyptian legend that he was the son of Amon, whose symbol was a ram. In the Syriac version of the pseudo-Callisthenes he is also given this title. (Compare Budge, History of Alexander.)
