Midrash su Daniele 8:5

The eighth king was Alexander of Macedonia, who ruled from one end of the world to the other, as it is said, "And as I was considering, behold, an he-goat came from the west over the face of the whole earth" (Dan. 8:5). "Over the earth" is not written here, but "over the face of the whole earth." And not only that, but he wished to ascend to heaven in order to know what is in heaven, and to descend into the depths in order to know what is in the depths, and not only that, but he attempted to go to the ends of the earth in order to know what was at the ends of the earth. The Holy One, blessed be He, divided his kingdom among the four corners (or winds) of the heavens, as it is said, "And when he shall stand up, his kingdom shall be broken, and shall be divided towards the four winds of the heaven" (Dan. 11:4).
