Christoph Scheiner

Christoph Scheiner SJ (25 July 1573 (or 1575) – 18 June 1650) was a Jesuit priest, physicist and astronomer in Ingolstadt.

Augsburg/Dillingen: 1591–1605
Scheiner was born in Markt Wald near Mindelheim in Swabia, earlier margravate Burgau, possession of the House of Habsburg. He attended the Jesuit St. Salvator Grammar School in Augsburg from May 1591 until 24 October 1595. He graduated as a "rhetor" and entered the Jesuit Order in Landsberg am Lech on 26 October 1595. At the local seminary, he served his biennial novitiate (1595–1597) under the tutelage of Novice Master Father Rupert Reindl SJ. From 1597 to 1598, he finished his lower studies of rhetoric in Augsburg. He took his first vows before Father Melchior Stör, SJ and received the minor orders from the Augsburg suffragan bishop Sebastian Breuning. He spent the years 1598–1601 in Ingolstadt studying philosophy (metaphysics and mathematics). In 1603, Scheiner invented the pantograph, an instrument which could duplicate plans and drawings to an adjustable scale. From 1603 to 1605 he taught humanities: his years as a Latin teacher at the Jesuit grammar school in Dillingen earned him the title of Magister Artium.



Ingolstadt: 1605–1617
From the autumn of 1605 until 1609, Scheiner studied theology in Ingolstadt. Due to his invention of the pantograph, he had already gained celebrity status. Duke William V of Bavaria even invited him to Munich to demonstrate the instrument.

On 14 March 1609, he entered Holy Orders as a Deacon. He was ordained by suffragan bishop Marcus Lyresius. Scheiner finished his studies on 30 June 1609 with his first work, Theses Theologicae and with a disputation (PhD in theology). On 18 April 1609, he received his major orders from suffragan bishop Lyresius in Eichstätt, from where he went to Ebersberg to serve his tertianship with Father Johannes Pelecius S.J. In the years between 1610 and 1616/1617, Scheiner worked as a successor to Father Johannes Lantz S.J. in Ingolstadt, teaching mathematics (physics and astronomy) and Hebrew. He lectured on sun dials, practical geometry, astronomy, optics, and the telescope.

In 1611, Scheiner observed sunspots; in 1612 he published the "Apelles letters" in Augsburg. Mark Welser had the first three Apelles letters printed in Augsburg on 5 January 1612. They provided one of many reasons for the subsequent unpleasant argument between Scheiner and Galileo Galilei, which began when Galileo responded to the Apelles letters with his own Letters on Sunspots. Scheiner published in 1614 the Disquisitiones mathematicae in Ingolstadt with Johann Georg Locher, in 1615 Sol ellipticus in Augsburg and with Georg Schönberger Exegeses fundamentorum gnomonicorum in Ingolstadt, and in 1617 he published Refractiones coelestes, also in Ingolstadt. Scheiner took his remaining vows of poverty, chastity, obedience and loyalty before the Pope on 31 July 1617 in the town of Ingolstadt under Father Johannes Manhart S.J. In the very same year Scheiner made known his wish to go to China as a missionary. Father General Mutio Vitelleschi sent him a letter, however, telling Scheiner he had better stay in Europe and persevere with his mathematical studies. In the winter of 1617/1618, Scheiner returned to Innsbruck, Austria at the behest of Archduke Maximilian III.

Innsbruck/Freiburg/Neisse: 1617–1624
After November 1614, Archduke Maximilian III summoned Scheiner to Innsbruck several times to discuss astronomical and mathematical questions. The Archduke had received an astronomical telescope with two convex lenses which showed objects upside down and the wrong way round. Scheiner added a third lens, thus manufacturing a terrestrial telescope which allowed Maximilian to see the beautiful stretches of his country while standing upright. A portable camera obscura was developed by Scheiner in Innsbruck. Furthermore, a walkable camera obscura was constructed.

After the death of Maximilian III in 1618, Archduke Leopold V was appointed imperial representative of Tyrol and of the Upper Provinces. Like his predecessor Maximilian, Leopold V put his trust in Father Scheiner. Scheiner's "Oculus hoc est: Fundamentum opticum," containing many new insights into the physiological nature of the eye, was published in Innsbruck in 1619. The book had been written earlier in Ingolstadt. Oculus is subdivided into three parts: the first part treats the anatomy of the eye, the second part the refraction of the light ray inside the eye, and the third part deals with the retina and the visual angle. Scheiner once again chooses the way of observation and experiment. Like Kepler before him, he found that the retina is the seat of vision and that the optic nerve transmits the images from the retina to the brain. Scheiner was rebuked once more for going from Innsbruck to Hall in a heavily loaded coach drawn by six horses. Father General Vitelleschi wrote him a letter. Archduke Leopold V and Father Scheiner carried on a sizeable correspondence from 1620 until 1632. One of Scheiner's letters to Leopold from 1626 informs the Archduke that Galilei is not to hear of Scheiner's work concerning the sunspots.

The inventory of Leopold's library contains works by Tycho Brahe and Galileo Galilei: Leopold lead a friendly correspondence with Galilei. On 23 May 1618, Leopold received telescopes from Galilei, along with a treatise on the sunspots, the Discorso del Flusso e Reflusso del Mare.

Scheiner was the builder of the new Jesuit church in Innsbruck. Craftsmen began to work on the roof in July 1624, but September saw a sudden collapse of the middle part of the gallery and the sidewall facing the street. According to a new decision, the church had to be turned by 90° and be reconstructed.

Freiburg University was facing a decline at the beginning of the 17th century. It was on 16 November 1620, that Archduke Leopold summoned the Jesuit Fathers, first of all, the "most excellent by far" Christoph Scheiner. In the spring of 1621, Scheiner was recalled for reasons confirmed to be unknown: in fact it was Archduke Karl's wish to have Scheiner as his father confessor. Archduke Karl had travelled with Scheiner from Brixen to Vienna, from where he did not return to Neisse until sometime between 1621 and 1622. In February 1623, Scheiner was appointed Superior of the future college. Then the Spanish King Philipp IV chose Karl of Austria for the office of a vice-king of Portugal. Archduke Karl travelled to Madrid. Scheiner had to travel to Rome, to instigate the foundation of the new college in Neisse. Scheiner stayed in Rome longer than his duty required. In Rosa Ursina sive Sol, he wrote that he had been sent to Rome "ad summum pontificem, ob certa peragenda negotia" (Latin meaning "to the pontifical summons..."). Other theories, contending that Scheiner had been summoned to Rome as an expert astronomer because of Galilei, or that he felt his transfer to Neisse was a punishment, have not been confirmed. It was only 13 years later, that he returned to Neisse via Vienna, where he stayed for some time.

Rome: 1624–1633


When Scheiner went to Rome in 1624, friends asked him to write about his solar observations. At last he had time for mathematical books, among them Galilei’s Il saggiatore, which contains Galileo's work on sunspots. This was similar to Scheiner's own work (unsurprisingly, since both were observing at the same time) but led to allegations from both of plagiarism by the other, and to a deep enmity between the two scientists. In 1629 and 1630, Scheiner observed a series of mock suns (parhelia) and haloes, including a complex display on 24 January 1630. These were described in his book Parhelia, which had a profound influence on the work of René Descartes and later on Christiaan Huygens. His observations also included an eclipse on 8 April 1633. On 22 June 1633, Galilei received his sentence and had to renounce his claims, despite the protest sounding even from the Aristotelian side. Scheiner's influence on the trial cannot be proven. The trial files merely contain a small note mentioning that he had opposed the Copernicans. At the time of the trial, Scheiner was still in Rome, staying at the seminary for future priests.

Scheiner wrote three of his books in Rome: Rosa Ursina sive Sol (Bracciano, 1626–1630), on sunspots, which served as a standard work for research work on the sunspots for a long time. Rosa Ursina sive Sol contains four books. In the first part, Scheiner discusses the question of priority of discovery in regard to sunspots. The second part not only describes telescopes, different kinds of projection and the helioscope but also compares the optics of the telescope to the physiological optics of the eye. In the third book, Scheiner presents a comprehensive collection of the data from his observation of sunspots. Book 4 consists of two parts: the first part deals once again with solar phenomena like sunspots and sun flares, the sun's rotation period of 27 days and the inclination of its axis of rotation. In the second part, Scheiner mentions numerous passages and quotations from the Bible, the writings of the Church Fathers and philosophers to prove that his geocentric view is in accordance with the teachings of the Catholic Church. Scheiner published Pantographice, about the pantograph which he had invented as early as 1603, and finally in 1632/1633, Scheiner published his last work Prodromus, a pamphlet against the heliocentric theory which was published posthumously in 1651.

Vienna: 1633–1637
Father General Mutio Vitelleschi wrote his first letter to Scheiner in Vienna on 21 January 1634. Thus Scheiner must have returned to Vienna between December 1633 and January 1634. Scheiner was unwilling to go back to Neisse. In Vienna, Scheiner was forced to confront the insecure funding for his book Rosa Ursina sive Sol.

Neisse: 1637–1650
After 15 November 1637, Scheiner was in Neisse in Silesia. Scheiner's activities in Neisse: Advisor, Councilor of the Rector, Mentor and Father Confessor to the students. He died there, and his obituary from 1650 maintains that Scheiner had to stay in Vienna because of the war, that he had had to flee from Neisse with all his astronomical instruments, that he usually got up early, to write or read, take care of the garden and plant trees with his own hands. The author of this obituary mentions Scheiner's modesty and chastity while pointing out that he was envied by many and "struggled with envy himself." Christoph Scheiner died on 18 June 1650 in Neisse (now Nysa, Poland).

Legacy
The primary school in Markt Wald is named in memory of Christoph Scheiner. In Markt Wald, there is also a street and a plaque hangs in the town hall and an observation tower to his remembrance. In Ingolstadt, there is the Christoph-Scheiner-Gymnasium (a High School). The street to the observatory of the university in Munich and a road in Berlin (Charlottenburg) are named after Scheiner. In 1999, a coin (35-mm diameter), with Scheiner's face on it, was minted in Ingolstadt. Also a lunar crater is named after Scheiner (diameter: 110 km [68 mi], height of embankment: 5,500 m [18,000 ft], named by Riccoli). A postage stamp was issued in Austria (2005). The town museum in Ingolstadt shows an oil painting (after 1732), also the Studienbibliothek Dillingen a fresco (painter Ignaz Schilling, 1702–1773).
