My PhD project at the Europa-Universität Flensburg
I am conducting a cross-cultural research on astrolabic quadrants. My work is an extension of the replication technique regarding time reckoning astronomical instruments from the pre-modern period. One of the instruments is a northern projection quadrant of almucantars from 1326/27 for the Damascus region by Zayn al-Dīn [Shams al-Dīn] Abū ˁAbd Allāh Muḥammad ibn Aḥmad ibn ˁAbd al-Raḥīm al-Mizzī al-Ḥanafī (Mizzī for short, d. 1349), the other one is a southern projection Sutton-type quadrant from 1658 for the London region by Henricus [Henry] Sutton Londini (Sutton for short, d. 1665). My dissertation topic is "Analysis of the Practice with Two Astrolabic Quadrants from the 14th Century Damascus and the 17th Century London". I began working on this project, which is funded by a scholarship from the State of Schleswig-Holstein, on November 1st, 2021.
For my project, I have been adapting the astrolabic [portable] quadrants to the year of 2022 and to the Flensburg region. I am using digital tools such as 3D CAD software and programming languages for this purpose. The first step after the adaptation is producing paper & 3D-printed models for the instruments. Then, they are going to be produced with the same material as the historic precursors.
Mizzī’s manuscript on how to operate the front [almucantars] side of the quadrant has at least 10 copies with 3 different versions. His works about the back [al-mujayyab] side of the quadrants were also copied several times. Apart from Mizzī’s own works, about 40 percent of the treatises about the astronomical instruments from the Ottoman period are about portable quadrants. Despite this significance, there is a literature gap in the modern academic studies on this subject.
The main resource for the Sutton-type quadrants is John Collin’s (d. 1683) treatise with the title of "The Sector on a Quadrant or A Treatise containing the Description and Use of Four Several Quadrants; Two Small ones and two great ones, each rendred many ways, both general and Particular. Each of them Accomodated for Dyalling; so the Resolving of all Proportions Instrumentally; And for the ready finding the Hour and Azimuth Universally in the equal Limbe. Of the great use of Seamen and Practitioners in the MATHEMATICKS." from 1658. This resource has not been studied in detail neither.
Hence I am going to be replicating and analyzing the historical scientific practice by following the instructions from these treatises.
