Abstract: At the beginning of the XVII century, Kepler and Roeslin were much closer in stature than history commonly teaches us today. The appearance of the nova in 1604, precisely at the moment and in the place of the great conjunction marking the emergence of the fiery trigon, was held by Roeslin to confirm his previous prognostication of a “universal transformation” of the world. This extraordinary event gave occasion to “reports” written in German in 1604 by our two authors with such different methodological and theoretical outlooks. Beginning in 1606 with the publication of Kepler's De stella nova and lasting until Roeslin's death in 1616, a discussion arose between the two involving several of their works. We will focus on the antecedents and first phase of the discussion (1604—1606), giving particular attention to the problem of the “signification” of the nova in the context of contemporary eschatological expectations.
