Specialist Notes

FIRST EDITION. Christophorus Clavius (Bamberg, 1537 - Rome, 1612) addresses the scientific foundations of the construction of sundials providing various mathematical demonstrations and decisive solutions to many theoretical and practical problems. Work of considerable interest and usefulness in years in which the measurement of time was entrusted to the gnomons, who guaranteed a fair degree of accuracy, and is undoubtedly an extraordinary testimony of the authority of Clavius, an illustrious mathematician and astronomer. Known in Italy as Christopher Clavius and called the Euclid of the sixteenth century, the author is also remembered for his important contribution to the reform of the Gregorian calendar. The fascinating crater visible from the Earth located in the southern region of the Moon, the "Clavius" crater and the asteroid "20237 Clavius" bears the name of the mathematician.
