Where did Revelation spring from?

There is an intriguing relationship between the Eucharistic Prayer in Did. 10 and the installments in Revelation. The Didache's prayer concludes with the line 'Allow the prophets to give thanks as much as they wish'. Could it be possible, therefore, that Revelation's installments are examples of a prophet making use of this freedom? This possibility is explored in my, 'The Didache and Revelation' in J. A. Draper and C. Jefford (eds.) A Missing Piece of the Puzzle in Early Christianity  (Atlanta: SBL, 2015)

Garrow provides a much more compelling [than the preceding essay in the collection] argument that a conceptual relationship exists between the Didache and the Apocalypse, in their ethical visions, in eucharistic vocabulary, and in particulars in apocalyptic details. Not content to show conceptual parallels, Garrow, who has argued that the Didache predates the gospel of Matthew, also argues that the Didache predated the Apocalypse and “provided the creative fountainhead out of which Revelation was born” (512).
