The Saphea Arzachelis It was called the Saphea Arzachelis by Profat Tibbon (Jacob ben Makir), betterknown under the name of prophatius Judaeus, in a treatise dated 1263. http://www.astrolabes.org/saphea.htm
Extractions: The Saphea Arzachelis Many would argue that the highest level ever achieved by the astrolabe was an instrument style introduced by Gemma Frisius (1508-1555) in Louvain, Belgium in the middle of the 16th century. This instrument, called the "Astrolbum (sic) Catholicum" by Gemma, included innovations in the instrument itself and a standard of artistic execution that greatly influenced European instrument manufacturing. Hans Dorn (1430-1509) of Vienna produced an astrolabe in 1486 with virtually the same format as the Astrolabum Catholicum (the instrument survives and is in Poland). There is no way of knowing whether Gemma ever saw or heard of Dorn's astrolabe and simultaneous inventions in a time of rapid progress are not unusual. Gemma's "Astrolabum Catholicum" was an attempt to make an astronomical instrument that could be used anywhere by a wide range of users. An ordinary astrolabe requires a separate plate for each latitude which makes it impractical to produce an instrument that can be used anywhere at reasonable cost and convenience of use. In addition, the ordinary astrolabe, as flexible as it is, is not well suited for certain types of problems, particularly those expressed in celestial latitude and longitude. In order to overcome these shortcomings, Gemma Frisius designed an instrument that had an ordinary astrolabe on one side and adopted a form of astrolabe that can be used at any latitude for the other side and included a magnetic compass in the throne. This form makes a lot of sense since different problems are better suited for one type of astrolabe or the other.
The Astrolabe Quadrant with no moving parts was in 1288 by Jacob ben Mahir ibn Tibbon (12361304),more widely known by his Latin name of prophatius Judaeus or Profeit Tibbon. http://www.astrolabes.org/quadrant.htm
Extractions: The Astrolabe Quadrant The earliest known description of an astrolabe reduced to a quadrant with no moving parts was in 1288 by Jacob ben Mahir ibn Tibbon (1236-1304), more widely known by his Latin name of Prophatius Judaeus or Profeit Tibbon. Tibbon's treatise was quickly improved by Peter Nightingale whose account received wide distribution. The instrument was quickly named the quadrans novus (new quadrant) to differentiate it from the traditional quadrant or quadrans vetus (old quadrant). The basic idea behind the idea of the quadrans novus is that the stereographic projection that defines the components of a planispheric astrolabe is just as valid if the astrolabe parts are folded into a single quadrant. The result is an instrument that can perform many of the functions of a standard astrolabe at much lower cost, but without the intuitive representation of the sky provided by the rotating rete,. It is not clear how popular the astrolabe quadrant became as few examples survive. There were, however, a number of treatises on the instrument so there is reason to believe that many were made, perhaps of cardboard or wood. Further, it is possible that brass quadrants were not as highly prized as true astrolabes due to their simplicity and were recycled into other instruments. The astrolabe quadrant was more popular in the Ottoman Empire from the 17th century until the early 20th century The astrolabe quadrant in the picture is not a specific instrument but contains the arcs and scales that can be considered typical on a 14th or 15th century

Extractions: USING THE ASTROLABE The astrolabe was used to make a number of different astronomical calculations. Users could find things such as the altitude of a star or the sun, the position of the sun along its annual path through the zodiacal constellations (the ecliptic) as viewed from earth, the time of sunrise and and sunset and the length of day. Here are a few instructions for some of these calculations: Finding the altitude of a star or sun: Suspend the astrolabe by its ring and rotate the alidade until you see the Sun's shadow or the star through its sight. Note its altitude on the altitude scale. Finding the position of the sun along the ecliptic (the sun's annual path through the zodiacal constellations as seen from earth): Use the two circles on the back of the astrolabe which give the position of the sun for every date. Finding the time of sunrise: Determine the sun's position in the ecliptic. Rotate the rete until that point of the ecliptic is on the eastern horizon of the latitude plate. Read the time where the rule meets the limb.

Extractions: CLASSICAL ROOTS AND EARLY ISLAMIC PERIOD The real details of the astrolabes invention in ancient Greece have largely been lost. The third century BC mathematician Apollonius, of what is now Turkey, may have invented its stereographic projection of the celestial sphere. And the astronomer Hipparchus may have been familiar with that projection during the next century, or may have even invented the astrolabe then. A useful but inaccurate Islamic myth is that Ptolemy discovered the astrolabe when his celestial globe dropped under the hooves of his donkey. The astrolabe does resemble a celestial globe or armillary sphere that has been flattened into two dimensions. And its basic design has not changed over the millennia but only been enhanced by many different features.

Extractions: ONE BOOK, 1393 YEARS - A history of the Almagest 1.1 Introduction One book dominated astronomy for nearly one-thousand four-hundred years. This was the Almagest of Claudius Ptolemy. Why was just one book so influential and so dominant that it took so long to be surpassed? 1.2 Ptolemy Ptolemy lived in Egypt in the period when it was part of the Roman Empire. We know very little about him personally and the dates of his life (AD.100 to 178) are only approximate. He worked in the city of Alexandria. Alexandria is located on the northern (Mediterranean) coast of Egypt. It was a city renowned for learning and had a famous library and museum. Possibly, Ptolemy himself worked in one or other of these institutions. Ptolemy wrote in Greek, which was the scientific and philosophical language of his day. He is famous for writing many books on scientific subjects. These are: "Mathematical Syntaxis" (The Almagest) Astronomy "On the Apprations of the Fixed Stars and a Collection of Prognostics" Astronomy
