Isidore of Miletus’ nephew, Isidore the Younger, introduced the new dome design that can be viewed in the Hagia Sophia in present-day Istanbul, Turkey. The question is: what role did he play

The nature of the instrument invented by Isidorus can only be guessed - the Greek word normally means “compass” - and nothing is otherwise known about Hero’s book or Isidorus’ commentary on it.The third section of the so-called Book XV of Euclid’s Elements shows how to determine the angle of inclination (dihedral angle) between the faces meeting in any edge of any one of the five regular solids. Rules are given for drawing these isosceles triangles, and the rules are attributed to “Isidore our great teacher.” It may therefore be presumed that at least the third section of the book was written by one of his pupils.It is evident that Isidore had a school, and it would appear to have been in this school that Archimedes’ On the Sphere and the Cylinder and Measurement of the Circle - in which Eutocius had revived interest through his commentaries - were translated from their original Doric into the vernacular, with a number of changes designed to make them more easily understood by beginners. Historical context [edit | edit source] A renowned mathematician and engineer even before Justinian I commissioned him to build the Hagia Sophia in Constantinople, the Greek Isidore of Miletus had a storied career. As in the church of Saints Sergius and Bacchus in the same city, the stresses of the central dome are shared by half domes to the west and east, and the general similarity of plan has led to conjectures that the same architects built the earlier church. Isidore was undoubtedly a genius mathematician and possessed extraordinary engineering skills. You could not be signed in, please check and try again. A renowned mathematician and engineer even before Justinian I commissioned him to build the Hagia Sophia in Constantinople, the Greek Isidore of Miletus had a storied career. It is evident from a comparison of Eutocius’ quotations with the text of extant manuscripts that the text of these treatises which Eutocius had before him differed in many respects from that which we have today, and the changes in the manuscripts must, therefore, have been made later than Eutocius. The procedure begins with construction of an isosceles triangle with a vertical angle equal to the angle of inclination.

The dome rests upon four great arches springing from four huge piers; the pendentives between the arches were at that time a novel device. It is evident that Isidore had a school, and it would appear to have been in this school that Archimedes’ On the Sphere and the Cylinder and Measurement of the Circle - in which Eutocius had revived interest through his commentaries - were translated from their original Doric into the vernacular, with a number of changes designed to make them more easily understood by beginners. The finished product was built in admirable form for the Roman Emperor, “All of these elements marvellously fitted together in mid-air, suspended from one another and reposing only on the parts adjacent to them, produce a unified and most remarkable harmony in the work, and yet do not allow the spectators to rest their gaze upon any one of them for a length of time.”[9]. The first basilica was completed in 360 and remodelled from 404 to 415, but had been damaged in 532 in the course of the Nika Riot, “The temple of Sophia, the baths of Zeuxippus, and the imperial courtyard from the Propylaia all the way to the so-called House of Ares were burned up and destroyed, as were both of the great porticoes that lead to the forum that is named after Constantine, houses of prosperous people, and a great deal of other properties.”[5], The rival factions of Byzantine society, the Blues and the Greens, opposed each other in the chariot races at the Hippodrome and often resorted to violence. Isidorus of Miletus  After a great earthquake in 989 ruined the dome of Hagia Sophia, the Byzantine officials summoned Trdat the Architect to Byzantium to organize repairs. Emperor Justinian I commissioned the church to be rebuilt for the sake of state-sanctioned Christianity, approaching well-known mathematicians called Isidore of Miletus and Anthemius of Thalles, who created a building that even 15 centuries later is still considered one of the great architectural models of all time with its design, its symmetry and overall beauty. While there is no recod of Isidore passing away, when the re-building of the dome was requested, it was Isidore’s nephew, Isidore the Younger, who came to do the renovation.
