After this I saw, and behold, another came up, like a leopard, which had on its back four wings of a bird; the beast also had four heads, and dominion was given to it. Bible

“a leopard.” This is the Greek Empire of Alexander the Great, and the four wings represent great speed. Alexander became king in 336 BC, and had conquered from India to Ethiopia before his death in 323 BC. When he died, his kingdom was divided into four smaller kingdoms, the four heads of the beast. His generals Antipater and Cassander ruled Macedon and Greece; Lysimachus ruled Thrace and Asia Minor (Turkey); Seleucus I ruled Syria; and Ptolemy I ruled Palestine and Egypt.
