drakōn

Scholars are nearly unanimous that the lexical sense is a large, often supernatural serpent and that English "dragon" is traditional but somewhat misleading; LSJ glosses it "dragon, serpent" and notes it is interchangeable with ophis from Homer onward, while Ogden's monograph judges "serpent" the better general fit for its semantic field, with wings and fire-breathing rare in Greek dragons. The word's significance for Revelation runs through the Septuagint, where it became the standard rendering of the Hebrew chaos-monster terms tannin and liwyatan (and occasionally rahab and nachash), especially in adversarial or political contexts, while the more neutral keto was preferred for cosmogonic or zoological settings (Foerster, TDNT). The cosmic-combat background (Gunkel's Chaoskampf) is now traced primarily to Ugaritic sources, above all the seven-headed Lotan of the Baal Cycle whose description Isaiah 27:1 closely mirrors (Day, God's Conflict with the Dragon and the Sea); Watson's Chaos Uncreated presses a notable caution against over-applying the chaos category, though the direct Isaiah 27:1 / KTU 1.5 parallel remains its hardest case. On Revelation 12 itself the two main camps differ in emphasis rather than substance: Yarbro Collins reads the chapter through the Greco-Roman combat myth (the Leto-Apollo-Python story prominent in first-century Asia Minor), while Bauckham, Beale, and Fekkes treat the Old Testament and Daniel matrix as controlling, with the beasts of Revelation 13 as Leviathan (sea) and Behemoth (earth) forming a satanic counterfeit of the divine. Ian Paul synthesizes these as a "political cartoon" that drops biblical characters into the plot of the imperial Apollo myth so that the emperor becomes the dragon's beast. Aune (WBC), Koester (AYB), and Osborne (BECNT) hold eclectic mediating positions. Scholars also note that the firm identification of the Eden serpent with Satan was a late development still crystallizing in the New Testament period, which Revelation 12:9 brings to a head.
