In discussing the katechon, Thiel said the Roman emperor Nero was the proto-Antichrist.

Treat 'Christian eschatological/Schmittian framing' as satisfied by the Christian eschatological tradition; Carl Schmitt himself need not have named Nero. True: established Christian tradition and scholarship identify Nero as a precursor, type or first figure of the Antichrist. Examples would be early Christian sources such as interpretations of Revelation (666 as 'Neron Kaisar'), the Nero redivivus legend, Lactantius, Commodian, Sulpicius Severus, or Augustine's report of that view. Mostly true: Nero is widely treated as an Antichrist figure or type, but the specific 'proto-' (first or precursor) framing is not standard. Mixed: Nero appears only in some minority interpretations, alongside other equally standard 'first antichrist' figures such as Antiochus IV Epiphanes. Mostly false: the link is marginal or speculative. False: no recognised Christian tradition connects Nero with the Antichrist.

   “Even though his reputation in general was ambivalent, he became a central actor, often associated with the Antichrist figure in Christian eschatological teaching.”

The scholarly sources show that from the third century onward, Christian texts named Nero as the Antichrist of the Bible passages (E1), and that he was "often associated with the Antichrist figure in Christian eschatological teaching" through the Nero redivivus legend (E4). The Encyclopaedia Romana states that Nero was the first to persecute the Christians and that many believed he would come before the Antichrist, and it describes a popular belief that Nero was the Antichrist or his precursor (E2, E3). The same source notes that not all Christians shared that belief (E3), which shows the idea was disputed but still a popular part of the tradition. Christian texts from the third century onwards identified Nero with the Antichrist (E1, E4), and a popular belief held him to be the Antichrist or his precursor (E2, E3). This meets the 'true' standard in the criteria, so the claim resolves true.
