The ram that you saw with the two horns stands for the kings of Media and Persia.

I saw it approaching the ram. It went into a fit of rage against the ram and struck it and broke off its two horns. The ram had no ability to resist it. The goat hurled the ram to the ground and trampled it. No one could deliver the ram from its power.

I saw that the ram was butting westward, northward, and southward. No animal was able to stand before it, and there was none who could deliver from its power. It did as it pleased and acted arrogantly.

It came to the two-horned ram that I had seen standing beside the canal and rushed against it with raging strength.
