As concerning the rest of the beasts, they had their dominion taken away: yet their lives were prolonged for a season and time.

The Antichrist is the horn, and the body of the beast mentioned is more than likely the Antichrist as well, even though Rome was called a beast above. The Antichrist is referred to as the beast in Revelation 13, and his body given over to be burnt in the fire is mentiond by John in Revelation 19:20. The other beasts is not to be confused with the other empires mentioned above (Babylon, Persians, Greeks) since they were destroyed centuries ago, but they are the other kings who followed the Antichrist, who were not thrown into the the Lake of Fire immediately with the Antichrist, perhaps they are given an extended time to repent.
