Aphrahat the Persian Sage : Again the ram was lifted up and exalted, and it pushed with its horns toward the west, and toward the north and toward the south, and it humbled many beasts. And they could not stand before him, until the he-goat came from the west and struck the ram and broke his horns and humbled the ram completely. But the ram was the king of Media and Persia, that is, Darius; and the he-goat was Alexander, the son of Philip, the Macedonian.… And the he-goat of the goats came up from the region of the Greeks and exalted himself against the ram, and he struck him and broke both his horns, the greater and the lesser. And why did he say that he broke both his horns? Clearly because he humbled both the kingdoms that he ruled; the lesser, that of the Medes, and the greater, that of the Persians. But when Alexander the Greek came, he killed Darius, king of Media and Persia. — DEMONSTRATIONS 5:5 Ishodad of Merv : The words "breaking its two horns," that is, the two powers, which Darius possessed, as the kingdom was subjected to two races, since the Medes and Persians were indicated together. In the same manner Cyrus, who was the first to rule, was a Mede on his mother's side and a Persian on his father's side. As their first king was called a Persian and a Mede, so the peoples, who were under his dominion, were indicated with the same names, because these two territories made a single kingdom. — COMMENTARY ON Daniel 8:7
