1) "And I stood on the sand of the sea, and saw a beast (kingdom) rise up out of the sea, having seven heads and ten horns, and upon his horns ten crowns, and upon his heads the name of blasphemy. 2) And the beast that I saw was like unto a leopard, and his feet were as the feet of a bear, and his mouth as the mouth of a lion; and the dragon gave him his power, and his seat (throne) and great authority. 3) And I saw one of his heads as it were (slain) wounded to death,(Greek: εσφαγμενην), and his deadly wound was healed: and all the world wondered after the beast."
John is instructed to record a series of events: the things which he had seen, the things that are, and the things which shall be hereafter: Revelation 1:19. After the seven letters to the seven churches, a door opens in heaven and John is taken up in the spirit. The large majority of the things recorded in Revelation consists of futuristic events, that extend far beyond John's world, to the end of the age. These events transpire during the last seven years of world history and move the reader forward, into the the time of the end and, the second coming of Yeshua HaMashiach.
We are told that Revelation is full of symbolic imagery and it's hard to understand so, we expect to be confounded and confused. We were told how scripture should be interpreted and now, we hold onto centuries-old interpretations for dear life and pass them on, conditioning future generations with several flawed interpretations. One of these flawed interpretations is the theory, that the seven heads of the beast, are the seven hills of Rome, moving the fourth beast, the antichrist-tribulation kingdom into Europe.
