Uniquely among the books of the New Testament, Revelation never cites Scripture directly and uses no citation formulae to indicate allusions. Yet John the Seer’s vision of God’s heavenly empire, casting the New Jerusalem as a heavenly metropolis and Babylon-Rome as a defeated enemy, repeatedly borrows words and imagery from Scripture. Indeed, Revelation contains more allusions to Scripture than any other early Christian text or the contemporary Jewish and Christian apocalypses. Despite this saturation of allusions, the idiosyncratic characteristics of Revelation complicate an intertextual analysis of John’s apocalypse. John seemingly diverges from the Septuagint and other ancient Greek translations, typically reflecting the recension preserved in the Masoretic Text. Furthermore, John combines multiple texts to generate a single image, entangling the readers in a web of prophetic allusions. The crush of marginalia in scholarly editions point toward this multifaceted intertextuality, but printed editions constrained by the spatial limitations of the page cannot graphically display the overwhelming density of Revelation’s allusions. Online editions, however, circumvent these physical restrictions. Using Rev 17:1-18:24 and 21:1-22:7 as case studies, this paper demonstrates the potential of online annotated editions to represent visually John’s reapplication of Scripture. Free from the spatial constraints of printed texts, online editions can provide fuller, dynamic references. Allusions in the body text can be color-coded, and the marginal references can be hyperlinked to source texts in the MT and LXX. Online editions also provide flexibility, as users can toggle citations of individual texts, selecting the source texts and text-forms they prefer. Expanding beyond case studies to whole books will provide enhanced visual tools, such as heat maps to indicate clusters of citations or recurring imagery. Though digitally annotated editions will not solve the riddles of Revelation’s intertextual allusions, they will expand our tools for interpreting John’s immersive vision of God’s heavenly empire.
