It should not be assumed that wherever a palace is mentioned by the historians the “Great Palace” is the one referred to, and it must be remembered that the palace described in the _Ceremonies_ was the result of gradual growth: indeed, what is required is a chronological analysis of its history. We have seen in the first chapter that according to the _Paschal Chronicle_ Constantine built a palace by the hippodrome, and the _Notitia_ mentions the palaces of Placidia and Marina in the same neighbourhood. According to Procopius the palace was almost rebuilt by Justinian, but he only specifically mentions the Chalké. Remains of a palace now on the sea-wall, exactly to the south of the curve of the hippodrome, are thought to be portions of the palace “Hormisdas” which Justinian occupied before he came to the throne (B, on Plan, Fig. 2). Close to the sea-wall farther to the west was the double church of SS. Sergius and Bacchus and SS. Peter and Paul, of which the first survives as Little Sancta Sophia (A, on Fig. 2). These were early works of Justinian, and his monogram and that of Theodora appear on the capitals of S. Sergius. Procopius tells us that the church of S. Sergius was “close to the king’s palace which was formerly called by the name of Hormisdas. This was once his own private house,” and when he became emperor “he joined it to the other imperial apartments.” The Great Palace was higher up the slope, against the hippodrome and Augusteum, to which its gates opened. It was long after Justinian that the great palace reached its maximum development; the Chrysotriclinum was erected by his successor Justin II. The houses of Marina and Placidia were still in use at the end of the sixth century, although this is mentioned by neither Labarte nor Paspates. The wedding of the daughter of Phocas was celebrated in the former,[283] and “the Royal palace of Placidia” is referred to by John of Ephesus. The writer tells us that Tiberius II., the successor of Justin II., made large additions to the palace. Before he reigned alone the wife and daughters of Tiberius occupied the house of Hormisdas, “as it was situated just below the palace, and he would go down and spend the evening with them and return early in the morning to the palace.”[284] Justinian II. also added to the palace, and in the ninth century Theophilus built the Triconcha. Basil the Macedonian still further increased the assemblage of buildings. It is clear that in the time of Justinian there were at least four more or less separate palaces grouped together--the Great Palace, Hormisdas, and those of Marina and Placidia.
