The situation, however, is slightly more complicated than that for his grandfather was called Pier Vincenzo Rainaldi. As we mention below, Pier Vincenzo Rainaldi was an outstanding scholar and his friends gave him the nickname Dante (or Danti) after the brilliant author of the Divine Comedy. The name stuck, and Pier Vincenzo's son Guilio also became known as Danti. For simplicity, we shall use the name Egnatio Danti throughout this article. Egnatio was born into a family of artists and scholars with mathematical talents. Both his father, Guilio Danti, and grandfather, Pier Vincenzo Rainaldi (Danti), were goldsmiths and architects who had written works on art. His father, made little gold statues and also constructed astronomical and surveying instruments, while his grandfather had translated Johannes de Sacrobosco 's astronomy text of 1220

In 1562 he was asked by Cosimo I de' Medici, the second duke of Florence, to prepare maps and a huge terrestrial globe which is still preserved. The maps were hung on the walls in the Palazzo Vecchio in Florence. Cosimo became first grand duke of Tuscany in 1569 and he appointed Danti to be professor of mathematics at Pisa. However Cosimo died in 1574 and Danti's position became insecure. In 1576 he had to leave Tuscany and he went to Bologna. From 1577 Danti mapped the area around Perugia, and in the same year he was appointed professor of mathematics at Bologna. He also accepted a commission to map the Papal states. In 1574 Danti detected the 11 day error in the calendar and from that time on became a leading figure in calendar reform. He designed and published work on astronomical instruments, an interest which led him to discover the 11 day error. He built an instrument to determine the true equinox so that the calendar might be corrected and constructed an astronomical quadrant. He built other instruments, namely ones to indicate the wind direction and a surveying instrument. Among Danti's mathematical publications are editions of some of Euclid 's works.

Dr. Kim H. Veltman V Instrumentation and Science Introduction Astronomy Optics Perspective ... Modern Developments 1. Introduction The development of perspective had fundamental consequences for science, art, the environment and the imagination. Each of these domains will be considered in turn in the chapters that follow. 2. Astronomy Ever since the Babylonians, there had been observation of the heavens and, already in Antiquity, there were instruments to observe the apparent motions of the planets and stars. Yet the focus of attention was on finding a pattern for phenomena such as eclipses of the sun and moon. Since the heavens were assumed to be unchanging, astronomy became primarily a conceptual problem of accounting for a set of recurring events. Indeed, once a basic catalogue of stars visible to the naked eye had been made, there was little incentive to look more closely. Hence, paradoxically, although ancient astronomy produced various instruments for observation of the heavens, it remained in many ways unvisual: a question of deceptive appearances1 rather than of visual truth. The development of the planisphere and astrolabe2 imposed a deductive grid on the heavens, not unlike that of Ptolemy's projection in his

Home E-mail to a Friend Print The Sun in the Church J. L. HEILBRON THE COPERNICAN REVOLUTION, which displaced the earth from its ancient seat at the center of the universe, is often cited as the beginning of modern science. Not only did Copernicanism correct an error dating to antiquity by substituting the sun for the earth as the center of the solar system, but it also challenged the cosmological teachings of the Roman Catholic Church, thereby setting up the new scientific cosmology as the rallying point of opposition to dogma. The culmination of the Copernican triumph is the morality play that was enacted in the trial of Galileo. There the Church is portrayed as quite willing to impose the heavy hand of censorship, and worse, to suppress ideas that would one day open wide the windows of scientific freedom. Drawing of the meridiana, Santa Maria degli Angeli, Rome, 1703 Christian theologians had decreed at the Council of Nicaea in 325 A.D. that Easter should be celebrated on the first Sunday after the first full moon after the vernal equinox (the day of the equinox is a day when the hours of daylight and darkness are equal). The full moon that follows the equinox can readily be observed in principle and often in practice. One then needs only to recognize the equinox, wait until the next full moon, and declare the following Sunday to be Easter. That straightforward procedure gives the right date for Easter, but not enough time to prepare for it. Therein lies an administrative predicament. To further complicate matters, the equinox and the full moon take place at different times at different places on earth, as, of course, does Sunday. Even if solar and lunar observations everywhere in the far-flung congregations of the Church were entirely accurate, Easter could well end up being celebrated on different days in different places. That was unacceptable to an organization struggling to make good its claims to unity and universality.
