We do not even know his German name, although various possibilities have been suggested. Clavius grew up during the initial stages of the Protestant Reformation in a region of Germany, Franconia, that remained Catholic. Three years after he was born, Ignatius de Loyola founded the Jesuit order with ten initial members; its membership had reached about a thousand by 1555, when Clavius was admitted to the order in Rome, a month before his seventeenth birthday. In 1556 he was sent to the university of Coimbra in Portugal, where the Jesuits had founded their own college. Here he took the normal university curriculum but excelled in the mathematical subjects, and his observation of the total solar eclipse of 1560 made him decide that astronomy would be his life's work. In 1560 he returned to Rome and began his study of theology at the Collegio Romano . He was ordained in 1564 while still pursuing his theological studies. In 1575 he became a full member of the order. He began teaching the mathematical subjects at the college as early as 1564 and, except for a two-year stay in Naples, he was on the faculty of the Collegio Romano until his death in 1612.

As an astronomer Clavius held strictly to the geocentric model of the solar system, in which all the heavens rotate about the Earth . Though he opposed the heliocentric model of Copernicus , he recognized problems with the orthodox model. He was treated with great respect by Galileo , who visited him in and discussed the new observations being made with the telescope ; Clavius had by that time accepted the new discoveries as genuine, though he retained doubts about the reality of the mountains on the

Z Christoph Clau, mathematician and astronomer, whose most important achievement related to the reform of the calendar under Gregory XIII ; born at Bamberg, Bavaria, 1538; died at Rome, 12 February, 1612. The German form of his name was latinized into "Clavius". He entered the Society of Jesus in 1555 and his especial talent for mathematical research showed itself even in his preliminary studies at Coimbra. Called to Rome by his superiors as teacher of this branch of science at the well-known Collegium Romanum, he was engaged uninterruptedly there until his death. the greatest scholars of his time, such men as Tycho Brahe, Johann Kepler, Galileo Galilei clavis , "key"), that he was appointed a cardinal , that he met his death by the thrust of a mad bull, etc. His relations with Galilei , with whom he remained on friendly terms until his death, have also been often misrepresented. The best evidence of the actual achievements of the great man is presented by his numerous writings, which at the end of his life he reissued at Mainz in five huge folio volumes in a collective edition under the title, "Christophori Clavii e Scoietate Jesu opera mathematica, quinque tomis distributa". The first contains the Euclidian geometry and the "Spheric" of Theodosius (Sphaericorum Libri III); the second, the practical geometry and algebra; the third is composed of a complete commentary upon the "Sphaera" of Joannes de Sacro Bosco (John Holywood), and a dissertation upon the astrolabe; the fourth contains what was up to that time the most detailed and copious discussion of gnomonics, i.e. the art of constructing all possible sun-dials; finally, the fifth contains the best and most fundamental exposition of the reform of the calendar accomplished under

In fact, except for a period in Naples around 1596 and a visit to Spain in 1597, Clavius was to remain Professor of Mathematics at the Collegio Romano for the rest of his life. The Julian leap-year rule created 3 leap years too many in every period of 385 years. As a result, the actual occurrence of the equinoxes and solstices slowly moved away from their calendar dates. The date of the spring equinox determines the date of Easter so the church began to press for reform. Clavius proposed that Wednesday, Oct. 4, 1582 (Julian) should be followed by Thursday, Oct. 15, 1582 (Gregorian). He proposed that leap years occur in years exactly divisible by four, except that years ending in 00 must be divisible by 400 to be leap years. This rule is still used today and is so accurate that no further reform of the calendar will be necessary for many centuries.

Known as the "Euclid of the 16th century ," he distingnished himself in mathematical research at Coimbra and was appointed to the chair of mathematics at the Collegium Romanum . He devised a method of dividing a measuring scale which was the precursor of the so-called Vernier's measuring instrument, but his greatest achievement was the execution and success of the Gregorian Calendar reform which prevailed through his efforts. His numerous scientific works have been published collectively under the title of "Christophori Clavii e Societate Jesu Opera Mathematica quinque tomis distributa." Among them are a practical geometry and algebra, an exposition of gnomonics, and a treatise on the Gregorian Calendar reform.
