Parallels of Revelation and Ezekiel.
Isaiah, Jeremiah, Ezekiel and Daniel Zechariah and Malachi contribute to our knowledge of Revelation. Also, fulfilled prophecy makes prophecy everywhere easier to understand. Of the Old Testament texts, however, Isaiah makes Revelation more understandable to me than Ezekiel. But there are remarkable parallels between Revelation and Ezekiel, two books written about 600 years apart. Some of them are listed here.
