Christoph Schissler , also Christoff Schissler , Christoffer Schissler and Christoph Schißler (* around 1531 probably in Augsburg ; † September 14, 1608 in Augsburg) was a German instrument maker .

Life

The Perlach Tower in 1818 and 2014, clearly recognizable as a Christoph Schissler sundial

Little is known about Schissler's childhood and youth; he lived most of the time in Augsburg , where he made nautical instruments such as astrolabes , quadrants and armillary spheres . He was a trained belt maker and received the title of master in 1553 at the age of 22. He described himself as a geometrical and astronomical foreman at Augspurg .

In 1561, the Augsburg magistrate commissioned Christoph Schissler to design and install four sundials on the Perlach Tower, which remained there for around 350 years until the tower was restored in the 20th century, after which they were replaced by large clocks with pointers. Schissler received 400 guilders for this, and his wife as an assistant received another 6 guilders.

He also invented a portable sundial that could be set to correctly show the time in the different latitudes between England and Italy. Schissler was during his lifetime a European-known and famous instrument maker, whose work in the emerging at the time curiosities occupied a prominent place of the noble houses.

In 1571 Schissler traveled to the court of Elector August of Saxony in Dresden and in 1583 to the court of Emperor Rudolf II in Prague .

In later years he occupied himself with the mapping and surveying of Augsburg and received 500 guilders from the magistrate in 1602 for the submission of a map of the city of Augsburg and the surrounding area. He had his own study room, in which his son Hans Christoph continued his work. This scholar's room is reconstructed in the Maximilian Museum in Augsburg.

Schissler's workshop

In a letter to August von Sachsen from 1572, he lists what his workshop was able to deliver:

I offer globes of heaven and earth, spheres, astrolabes, planispheres , strangely wonderful horologies that incline and decline, also strange compasses that magnetically show the way and the hour, as well as various clocks that work inside and outside, at solar or moonlight to show the correct time and hour day and night. Also a particularly skilful drinking utensil, on which the text of the 20th chapter from the 4th book of the kingdoms ( 2 Kings 20  EU ) about the Horologium of Achaz is engraved: since the shadow has run back etc. I could also create an instrument with which Text of the 10th chapter Joshua ( Jos 10.13  EU ): Since the sun stood still. Likewise, an instrument would have to be made by which the four cardinal points are shown in all known and unknown places and in sun, moon or starlight, even without any light in pitch dark night. Your Grace would certainly find this instrument helpful in finding a preconceived location in the forest.

In 1569, Christoph Schissler handed over a measuring tool to August von Sachsen, the Quadratum Geometricum , which is nowadays considered by several researchers to be the most valuable of all scientific tools of the 16th century.

legacy

Over 100 of his instruments are preserved worldwide and can be viewed in museums. His work was intended for the entire European market, which can be seen from the labels and settings for different languages ​​and latitudes.

In 2015, the London auction house Bonhams auctioned a combined brass astrolabe with sundial from 1566 for £ 146,500 (about € 200,000).
