First Edition of Manfredi’s collected lessons in astronomy published posthumously. Eustachio Manfredi, a Jesuit scholar, was a mathematician and astronomer from Bologna who was also active in the field of poetry and asked many philosophical questions of his peers. Manfredi’s engagement with the study of astronomy had always been in conjunction with other offices he held in mathematics until he cofounded the Observatory of the Bologna Institute of Sciences in 1712. At the Observatory, Manfredi was able to study the problem of the annual parallax, or displacement, of fixed stars; his study was significant since it could offer solid proof for the heliocentric model of the universe. It was a late publication of his complex treatise on this topic, his De annuis inerrantium (1729), which unfortunately left it open for other scholars to publish their findings in his research area. Seeing that cultural climate was not yet ready to accept the new heliocentric theories, Manfredi rededicated himself to the fruit of reporting accurate but intellectual observations in astronomy. These collected lessons were published ten years after his death as the Instituzioni Astronomiche and remain an impressive literary work. His ideas valued and preserved even after his death, Manfredi characterized the Bolognese astronomical observations of the late 1600s and over the next century. He is largely credited for encouraging the reality of the heliocentric system. As an indirect result of Manfredi’s work, the Church admitted the scientific nature of Galileo’s works.
