LITERATURE:
Cf. Dumont, A., ‘Musée Sainte-Irène’ in Revue Archéologique, 1868, II, pp.236-263, p.260, mentioning two fragments of porphyry in the middle of the street, near the Mosque of Mehmet II; Mendel, G., Catalogue des sculptures grecques, romaines et byzantines, Constantinople, 1914, nos.1175 (2391) vol.III, p.419, for the fragments of an imperial sarcophagus in porphyry.

FOOTNOTES:
For the Romans, porphyry was the Imperial marble par excellence, and from Constantine the Great until the end of the 5th century, but probably also later, it was used to create sarcophagi for the emperors and members of the Imperial families. This particular stone was connected with the Imperial family because of its red colour, recalling the violet and red shades of the purple (porphyra), the precious colour assigned only to emperors and their relatives. In Constantinople, a room of the Imperial palace was called Porphýra, located on one of the palace terraces overlooking the Sea of Marmara and the Bosphorus. It was perfectly square in shape with a pyramidal ceiling and was entirely covered in purple porphyry speckled with white dots: this was the room where the empresses gave birth to the heir of the Roman Empire, called Porphyrogénnētos, meaning ‘born in the purple room’.

Porphyry was widely used for building churches in the Christian Empire, and Justinian exhausted the supplies from Egypt by building the Great Church of Hagia Sophia, where still today a great amount of this material can be seen. The impressive Imperial sarcophagi were kept in the Church of the Holy Apostles, as well as the great porphyry sarcophagus of Constantine the Great, of which only a small fragment survives today in the Archaeological Museum of Istanbul.
