This leopard was the Grecian monarchy; a leopard is less than a lion, so was this monarchy at first, but yet durst fight with a lion; so did Alexander encounter Darius with a force very small to the other. A leopard also for his swiftness; therefore described with four wings on his back. The beast had also four heads, because his commanders that succeeded him were four of his chief commanders, that divided that empire into four parts between them; and these were the four heads to whom dominion was given, Ptolemy, Seleucus, Philippus, Antigonus, or, as others, Perdiccas and Meleager, Daniel 8:21,22. Dominion was given to it: Alexander did this by the mighty power of God; else how could he conquer Darius, that had six hundred thousand, with thirty thousand, and in so short a time go conqueror over Asia to the East Indies, I mean that part which now the Mogul possesseth, where he fought with Porus and beat him?
