 note = {Hagia Sophia is one of the world’s most famous cultural heritage sites because of its unique structural system,coexistence of religions,and various mosaics that were executed from the 6th to the 14th centuries.
 In Hagia Sophia, an interesting subject for scholars is the date of the mosaics. Attempts have been made to identify the correlation of materials and dates. Differences among the materials and techniques of each era can be determined by visual observation and measurement of tessera size.The characteristics of mosaics have also been identified by color spectral reflectivity survey. Now 10 samples of cover glass of tesserae from 2 mosaics (at South Gallery and South Aisle)are being analyzed to verify previous considerations. The possibility that both mosaics were executed in an earlier period, such as from the 6th to the 9th centuries,may be pointed out on the basis of analysis of these samples.},
