Iter Exstaticum Coeleste [Ecstatic Journey into the Heavens] (1660): Volume 1

Iter Exstaticum Coeleste, published in 1660 as the second edition of Kircher's 1656 work Itinerarium Exstaticum, stands as an imaginative synthesis of early modern astronomy, natural philosophy, and sacred cosmology. Framed as an ecstatic, visionary journey through the heavens, the work draws on the long tradition of philosophical ascent—from Platonic and Neoplatonic models of intellectual illumination to medieval dream visions—while grounding its celestial itinerary in the latest astronomical debates of the seventeenth century. Under the guidance of the angelic companion Cosmiel, the narrator is led beyond the sublunary world and through the planetary spheres, confronting competing cosmological systems, from Ptolemaic geocentrism to Copernican heliocentrism and Tychonic compromise. Rather than offering a single dogmatic resolution, the text stages astronomy as a dynamic field of inquiry, in which mathematical models, sensory experience, and theological commitments must be held in careful balance. Authored by Athanasius Kircher and edited and refined by Gaspar Schott, the Iter Exstaticum Coeleste exemplifies the Jesuit intellectual project of reconciling empirical investigation with divine order. Kircher's expansive curiosity finds here a literary form capable of accommodating wonder, speculation, and disciplined inquiry alike, while Schott's editorial hand lends clarity and structure to the argument. Schott also actively defends Kircher's ideas against ecclesiastical censors who had raised objections to the earlier 1656 work, offering theological and methodological justifications to secure its acceptability within Church oversight. In guiding the reader through the heavens, Kircher and Schott invite contemplation not only of the structure of the cosmos, but of humanity's place within a universe understood as both mathematically ordered and theologically meaningful.
