A small Byzantine building, now used for Moslem worship under the name of Balaban Aga Mesjedi, is situated in the quarter of Shahzadé, off the south side of the street leading to the mosque of Sultan Mehemed and the gate Edirne Kapoussi. Mordtmann 460 proposes to identify it with the church of the Theotokos in the district of the Curator (τοῦ Κουράτορος), the foundation of which is ascribed to Verina, the consort of Leo Macellus (457-474). 461 The only reason for this conjecture is that the church in question stood where Balaban Aga Mesjedi stands, in the neighbourhood of the forum of Taurus, 462 now represented by the open area beside the War Office and the mosque of Sultan Bajazet. But the plan of the building does not correspond to the description given of the Theotokos in the district of the Curator. The latter resembled the Holy Sepulchre at Jerusalem, 463 and was therefore circular, whereas Balaban Aga Mesjedi is a hexagon. Indeed, it may be questioned whether the building was ever a church, seeing it has no room for either a berm, or an apse, or an eikonostosis. It may have been the library of a monastic establishment.
Internally the building is an accurate hexagon, with a deeply
arched recess in each side. Five recesses have a window,
while in the sixth recess, instead of a window, there is a door.
The cornice and wooden ceiling are Turkish. Externally the edifice
shows four sides, two circular and two flat projecting bays,
arranged in alternate order. In each of the circular sides are two
windows, while the fifth window and the entrance are respectively
in the flat sides. A Turkish narthex fronts one-half of the
building. (Plate LV.)

This mosque is situated in the quarter of Psamathia, at a short distance to the north of the Armenian church of S. George (Soulou Monastir), which stands on the site of the Byzantine church of S. Mary Peribleptos. Paspates, 464 who first recognized the Byzantine character of the edifice, regards it as the chapel attached to the convent of the Gastria (Μονὴ τῶν Γαστρίων, τὰ Γάστρια, i.e. in the district of the Flower-pots). His reasons for that opinion are: first, the building is situated in the district of Psamathia, where the convent of the Gastria stood; secondly, it is in the neighbourhood of the Studion, with which the convent of the Gastria was closely associated during the iconoclastic controversy; thirdly, the copious and perennial stream of water that flows through the grounds below the mosque would favour the existence of a flower-garden in this part of the city, and thus give occasion for the bestowal of the name Gastria upon the locality. The argument is by no means conclusive. A more fanciful explanation of the name of the district is given by Byzantine etymologists after their wont. According to them the name was due to the circumstance that the Empress Helena, upon her return from Jerusalem with her great discovery of the Holy Cross, disembarked at Psamathia, and having founded a convent there, adorned its garden with the pots (τὰ γάστρια) of fragrant shrubs which accompanied the sacred tree on the voyage from Palestine. 465 More sober historians ascribe the foundation of the convent to Euphrosyne, the step-mother of the Emperor Theophilus, 466 or to his mother-in-law Theoctista. 467 Both ladies, it is certain, were interested in the House, the former taking the veil there, 468 while the latter resided in the immediate neighbourhood. 469 Probably the convent was indebted to both those pious women for benefactions, and it was unquestionably in their day that the monastery acquired its greatest fame as the centre of female influence in support of the cause of eikons. Theoctista was especially active in that cause, and through her connection with the court not only strengthened the opposition to the policy of her son-in-law, but also disturbed the domestic peace of the imperial family. Whenever the daughters of Theophilus visited her she took the opportunity to condemn their father's views, and would press her eikons on the girls' lips for adoration. One day, after such a visit, Pulcheria, the youngest princess, a mere child, in giving an account of what had transpired, innocently told her father that she had seen and kissed some very beautiful dolls at her grandmother's house. Whereupon Theophilus, suspecting the real facts, forbade his daughter to visit Theoctista again. On another occasion the court fool, Denderis, surprised the Empress Theodora in her private chamber kissing eikons and placing them over her eyes. 'What are these things?' he inquired. 'My beautiful dolls which I love,' she replied. Not long afterwards the jester was summoned to amuse Theophilus while sitting at table. 'What is the latest news?' asked the emperor. 'When I last visited "mamma" (the jester's familiar name for the empress) I saw most beautiful dolls in her room.' Instantly the emperor rose, beside himself with rage, and rushing to his wife's apartments violently denounced her as a heathen and idolater. 'Not at all,' answered Theodora, in her softest accents, 'that fool of yours saw me and my maidens looking into a mirror and mistook the faces reflected there for dolls.' The emperor did not press the case, but a few days later the servants of Theodora caught Denderis and gave him a sound thrashing for telling tales, dismissing him with the advice to let dolls alone in the future. In consequence of this experience, whenever the jester was afterwards asked whether he had seen his 'mamma's' dolls recently, he put one hand to his mouth and the other far down his back and whispered, 'Don't speak to me about dolls.' 470 Such were the pleasantries that relieved the stern warfare against eikons.

On the occasion of the breach between Theodora and her son Michael III., on account of the murder of her friend and counsellor Theoctistos at Michael's order, she and her four daughters, Thekla, Anastasia, Anna, and Pulcheria, were confined in the Gastria, and there, with the exception of Anna, they were eventually buried. 471 At the Gastria were shown also the tombs of Theoctista, her son Petronas, Irene the daughter of Bardas, and a small chest containing the lower jaw of Bardas 472 himself. It is this connection with the family of Theophilus, in life and in death, that lends chief interest to the Gastria.
Although the building is now almost a complete ruin, it still preserves some architectural interest. On the exterior it is an octagonal structure, with a large arch on each side rising to the cornice, and thus presents a strong likeness to the Byzantine building known as Sheik Suleiman Mesjedi, near the Pantokrator (p. 25). The northern, southern, and western arches are pierced by windows. The entrance is in the western arch. The interior presents the form of an equal-armed cross, the arms being deep recesses covered with semicircular vaults. The dome over the central area has fallen in. The apse, semicircular within and showing five sides on the exterior, is attached to the eastern arm. Its three central sides are occupied by a triple-shafted window. Two shallow niches represent the usual apsidal chambers. A similar niche is found also on both sides of the entrance and on the eastern side of the northern arm of the cross. In the wall to the west of the southern arch is a small chamber. The joint between the apse and the body of the building is straight, with no bond in the masonry; nor is the masonry of the two parts of the same character. In the former it is in alternate courses of brick and stone, while in the latter we find many brick courses and only an occasional stone band. Evidently the apse is a later addition. In view of these facts, the probable conclusion is that the building was originally not a church but a library, and that it was transformed into a church at some subsequent period in its history to meet some special demand.

The church of S. Mary of the Mongols (τῶν Μογγολίων, τῶν Μουγουλίων, τοῦ Μουχλιοῦ, Μουχλιώτισσα), which stands on the heights above the quarter of Phanar, a short distance to the west of the Greek Communal School, was founded in the thirteenth century by Maria Palaeologina, a natural daughter of the Emperor Michael Palaeologus (1261-1282). As the church has been in Greek hands ever since its foundation its identity cannot be disputed. The epithet given to the Theotokos in association with this sanctuary alludes to the fact that Maria Palaeologina married a Khan of the Mongols, 473 and bore the title of Despoina of the Mongols (Δέσποινα τῶν Μουγουλίων). 474 The marriage was prompted by no romantic sentiment, but formed part of the policy by which her father hoped to secure the goodwill of the world for the newly restored Empire of Constantinople. While endeavouring to disarm the hostility of Western Europe by promoting the union of the Latin and Greek Churches, he sought to conciliate the people nearer his dominion by matrimonial alliances with their rulers. It was in this way that he courted, with greater or less success, the friendship of Servia, Bulgaria, the Duchy of Thebes, and the Empire of Trebizond. And by the same method he tried to win the friendship of the formidable Mongols settled in Russia and Persia. Accordingly he bestowed the hand of one natural daughter, Euphrosyne, upon Nogaya, 475 who had established a Mongolian principality near the Black Sea, while the hand of Maria was intended for Holagu, famous in history as the destroyer in 1258 of the caliphate of Baghdad. Maria left Constantinople for her future home in 1265 with a great retinue, conducted by Theodosius de Villehardouin, abbot of the monastery of the Pantokrator, who was styled the 'Prince,' because related to the princes of Achaia and the Peloponnesus. A rich trousseau accompanied the bride-elect, and a tent of silk for a chapel, furnished with eikons of gold affixed to crosses, and with costly vessels for the celebration of the Holy Sacrifice. When the mission reached Caesarea news came that Holagu was dead, but since reasons of state inspired the proposed marriage, the bridal party continued its journey to the Mongolian court, and there in due time Maria was wedded to Abaga, the son and successor of Holagu, after the bridegroom had received, it is said, Christian baptism. 476
In 1281 Abaga was poisoned by his brother Achmed, 477 and Maria deemed it prudent, and doubtless welcome, after an absence of sixteen years, to return to Constantinople. She appears again in history during the reign of her brother Andronicus II. Palaeologus, when for the second time she was offered as a bride to the Mongolian prince, Charbanda, who then ruled in Persia, 478 the object of this new matrimonial alliance being to obtain the aid of the Mongols against the Turks, who under Othman had become a dangerous foe and were threatening Nicaea. With this purpose in view Maria proceeded to that city, both to encourage the defence of an important strategic position and to press forward the negotiations with Charbanda. The Despoina of the Mongols, however, did not comprehend the character of the enemy with whom she had to deal. Her contemptuous demeanour towards Othman, and her threats to bring the Mongols against him, only roused the spirit of the Turkish chieftain, and before the Greeks could derive any advantage from the 30,000 Mongolian troops sent to their aid, Othman stormed the fortress of Tricocca, an outpost of Nicaea, and made it the base of his subsequent operations. 479
The church was built for the use of a convent which the Despoina
of the Mongols, like many other ladies in Byzantine times, erected
as a haven of refuge for souls who had dedicated their lives to the
service of God (λιμένα
ψυχῶν κατὰ
θεὸν
προσθεμένων
βιοῦν). She also endowed it with
property in the immediate neighbourhood (περὶ
τὴν
τοποθεσίαν
τοῦ Φανάρι), as well
as with other lands both within and beyond the city, and while
Maria lived the nuns had no reason for complaint. But after her
death the property of the House passed into the hands of Isaac
Palaeologus Asanes, the husband of a certain Theodora, whom Maria
had treated as a daughter, and to whom she bequeathed a share in
the convent's revenues. He, as soon as Theodora died, appropriated
the property for the benefit of his family, with the result that
the sisterhood fell into debt and was threatened with extinction.
In their distress the nuns appealed to Andronicus III. Palaeologus
for protection, and by the decision of the patriarchal court, to
which the case was referred as the proper tribunal in such
disputes, the convent in 1351 regained its rights.
480
As already intimated, to this church belongs the interest of having always preserved its original character as a sanctuary of the Greek Orthodox Communion. This distinction it owes to the fact that the church was given to Christoboulos, the Greek architect of the mosque of Sultan Mehemed, as his private property, to mark the conqueror's satisfaction with the builder's work. The grant was confirmed by Bajazet II. in recognition of the services of the nephew of Christoboulos in the construction of the mosque which bears that Sultan's name. Twice, indeed, attempts were subsequently made to deprive the Greek community of the church, once under Selim I. and again under Achmed III. But, like the law of the Medes and Persians, a Sultan's decree altereth not, and by presenting the hatti sheriff of Sultan Mehemed the efforts to expropriate the building were frustrated. 481
Among the Turks the building is known as Kan Kilisse, the church of Blood, and the adjoining street goes by the name Sanjakdar Youkousou, the ascent of the standard-bearer, 482 terms which refer to the desperate struggle between Greeks and Turks at this point on the morning of the capture of the city. 483
Although the building has always been in Christian hands it has suffered alterations almost more drastic than any undergone by churches converted into mosques. The interior has been stripped of its original decoration, and is so blocked by eikons, chandeliers, and other ornaments as to render a proper examination of the church extremely difficult. In plan the church is a domed quatrefoil building, the only example of that type found in Constantinople. The central dome rests on a cross formed by four semi-domes, which are further enlarged below the vaulting level by three large semicircular niches. It is placed on a drum of eight concave compartments pierced by windows to the outside circular and crowned with a flat cornice. Externally the semi-domes and apse are five-sided. From the interior face of the apse and on its northern wall projects a capital, adorned with acanthus leaves, which, as it could never have stood free in this position, probably formed part of an eikonostasis in stone. The narthex is in three bays, the central bay being covered by a barrel vault, while the lateral bays have low drumless domes on pendentives. The entrance is by a door in the central bay, and from that bay the church is entered through a passage cut in the central niche of the western semi-dome, and slightly wider than the niche. The end bays open, respectively, into the northern and southern semi-domes by passages or aisles terminating in a diagonal arch. The arches between these aisles and the western semi-dome are pierced, and thus isolate the western dome piers. On the south the church has been greatly altered; for the entire southern semi-dome and the southern bay of the narthex have been removed and replaced by three aisles of two bays each. These bays are equal in height, and are covered by cross-groined vaults with strong transverse pointed arches supported on square piers, the whole forming a large hall held up by two piers, and showing the distinct influence of Italian Gothic work. This part of the building is modern. On the eastern wall is a large picture of the Last Judgment.
The plan of this church may be compared with that of S. Nicholas

In a vacant lot of ground on the eastern declivity of the hill above the quarter of Balat, and at a short distance to the east of a mass of rock known as Kesmé Kaya, stands a Byzantine chapel to which the name Bogdan Serai clings. Although now degraded to the uses of a cow-house it retains considerable interest. Its name recalls the fact that the building once formed the private chapel attached to the residence of the envoys of the hospodars of Moldavia (in Turkish Bogdan) at the Sublime Porte; just as the style Vlach Serai given to the church of the Virgin, lower down the hill and nearer the Golden Horn, is derived from the residence of the envoys of the Wallachian hospodars with which that church was connected. According to Hypselantes, 484 the Moldavian residence was erected early in the sixteenth century by Teutal Longophetes, the envoy who presented the submission of his country to Suleiman the Magnificent at Buda in 1516, when the Sultan was on his way to the siege of Vienna. Upon the return of Suleiman to Constantinople the hospodar of the principality came in person to the capital to pay tribute, and to be invested in his office with the insignia of two horse-tails, a fur coat, and the head-dress of a commander in the corps of janissaries. Gerlach 485 gives another account of the matter. According to his informants, the mansion belonged originally to a certain Raoul, who had emigrated to Russia in 1518, and after his death was purchased by Michael Cantacuzene as a home for the Moldavian envoys. It must have been an attractive house, surrounded by large grounds, and enjoying a superb view of the city and the Golden Horn. It was burnt 486 in the fire which devastated the district on the 25th June 1784, and since that catastrophe its grounds have been converted into market gardens or left waste, and its chapel has been a desecrated pile. But its proud name still haunts the site, calling to mind political relations which have long ceased to exist. The chapel stood at the north-western end of the residence and formed an integral part of the structure. For high up in the exterior side of the south-eastern wall are the mortises which held the beams supporting the floor of the upper story of the residence; while lower down in the same wall is a doorway which communicated with the residence on that level. Some of the substructures of the residence are still visible. It is not impossible that the house, or at least some portion of it, was an old Byzantine mansion. Mordtmann, 487 indeed, suggests that it was the palace to which Phrantzes refers under the name Trullus (ἐν τῷ Τρούλῳ). 488 But that palace stood to the north of the church of the Pammakaristos (Fetiyeh Jamissi), and had disappeared when Phrantzes wrote. Gerlach, 489 moreover, following the opinion of his Greek friends, distinguishes between the Trullus and the Moldavian residence, and places the site of the former near the Byzantine chapel now converted into Achmed Pasha Mesjedi, to the south of the church of the Pammakaristos. 490

Opinions differ in regard to the dedication of the chapel. Paspates, 491 following the view current among the gardeners who cultivated the market-gardens in the neighbourhood, maintained that the chapel was dedicated to S. Nicholas. Hence the late Canon Curtis, of the Crimean Memorial Church in Constantinople, believed that this was the church of SS. Nicholas and Augustine of Canterbury, founded by a Saxon noble who fled to Constantinople after the Norman conquest of England. What is certain is that in the seventeenth century the chapel was dedicated to the Theotokos. Du Cange mentions it under the name, Ecclesia Deiparae Serai Bogdaniae. 492
Mordtmann has proved 493 that Bogdan Serai marks the site of the celebrated monastery and church of S. John the Baptist in Petra,—the title 'in Petra' being derived from the neighbouring mass of rock, which the Byzantines knew as Παλαιὰ Πέτρα, and which the Turks style Kesmé Kaya, the Chopped Rock.
According to a member of the monastery, who flourished in the eleventh century, the House was founded by a monk named Bara in the reign of Anastasius I. (491-518) near an old half-ruined chapel dedicated to S. John the Baptist, in what was then a lonely quarter of the city, between the Gate of S. Romanus (Top Kapoussi) and Blachernae. The monastery becomes conspicuous in the narratives of the Russian pilgrims to the shrines of the city, under the designation, the monastery of S. John, Rich-in-God, because the institution was unendowed and dependent upon the freewill offerings of the faithful, which 'by the grace of God and the care and prayers of John' were generous. Thrice a year, on the festivals of the Baptist and at Easter, the public was admitted to the monastery and hospitably entertained. It seems to have suffered during the Latin occupation, for it is described in the reign of Andronicus II. as standing abandoned in a vineyard. But it was restored, and attracted visitors by the beauty of its mosaics and the sanctity of its relics. 494
In 1381 a patriarchal decision conferred upon the abbot the titles of archimandrite and protosyngellos, and gave him the third place in the order of precedence among the chiefs of the monasteries of the city, 'that thus the outward honours of the house might reflect the virtue and piety which adorned its inner life.' 495 Owing to the proximity of the house to the landward walls, it was one of the first shrines 496 to become the spoil of the Turks on the 29th of May 1453, and was soon used as a quarry to furnish materials for new buildings after the conquest. Gyllius visited the ruins, and mistaking the fabric for the church of S. John the Baptist at the Hebdomon, gave rise to the serious error of placing that suburb in this part of the city instead of at Makrikeui beside the Sea of Marmora. 497 Gerlach 498 describes the church as closed because near a mosque. Portions, however, of the monastic buildings and of the strong wall around them still survived, and eikons of celebrated saints still decorated the porch. On an eikon of Christ the title of the monastery, Petra, was inscribed. Some of the old cells were then occupied by nuns, who were maintained by the charitable gifts of wealthy members of the Greek community.
The building is in two stories, and may be described as a chapel over a crypt. It points north-east, a peculiar orientation probably due to the adaptation of the chapel to the position of the residence with which it was associated. The masonry is very fine and regular, built in courses of squared stone alternating with four courses of brick, all laid in thick mortar joints, and pierced with numerous putlog holes running through the walls. It presents a striking likeness to the masonry in the fortifications of the city. The lower story is an oblong hall covered with a barrel vault, and terminates in an arch and apse. In the west side of one of the jambs of the arch is a small niche. The vault for one-third of its height is formed by three courses of stone laid horizontally and cut to the circle; above this it is of brick with radiating joints. Here cows are kept.
The upper story is m. 3.75 above the present level of the ground. It is a single hall m. 8.80 in length and m. 3.70 wide, terminating in a bema and a circular apse in brick. Over the bema is a barrel vault. A dome, without drum or windows, resting on two shallow flat arches in the lateral walls and two deep transverse arches strengthened by a second order of arches, covers the building. In the wall towards the north-west there is a window between two low niches; and a similar arrangement is seen in the opposite wall, except that the door which communicated with the residence occupies the place of the window. The apsidal chambers, usual in a church, are here represented by two niches in the bema. Externally the apse shows five sides, and is decorated by a flat niche pierced by a single light in the central side, and a blind concave niche, with head of patterned brickwork, in the two adjacent sides. The dome, apse, vaults, and transverse arches are in brick, laid in true radiating courses. The absence of windows in the dome is an unusual feature, which occurs also in the angle domes of S. Theodosia. The pendentives are in horizontal courses, corbelled out to the centre, and at each angle of the pendentives is embedded an earthenware jar, either for the sake of lightness, or to improve, as some think, the acoustics of the building. This story of the chapel is used as a hayloft.
A careful survey of the building shows clearly that the domical character of the chapel is not original, and that the structure when first erected was a simple hall covered with a wooden roof. Both the shallow wall arches and the deep transverse arches under the dome are insertions in the walls of an older fabric. They are not supported on pilasters, as is the practice elsewhere, but rest on corbels, and, in order to accommodate these corbels, the lateral niches, originally of the same height as the central window, have been reduced in height. A fragment of the original arch still remains, cut into by the wall arch of the dome. The flat secondary arches crossing the chapel at each end are similarly supported on corbels.
This view is confirmed by the examination of the plaster left upon the walls. That plaster has four distinct coats or layers, upon all of which eikons in tempera are painted. 499 The innermost coat is laid between the transverse dome arches and the walls against which they are built. Those arches, therefore, could not have formed parts of the building when the first coat of plaster was laid, but must be later additions.
In keeping with this fact, the second coat of painted plaster is found laid both on the arches and on those portions of the old work which the arches did not cover.
The secondary arches under the transverse arches at each end belong to a yet later period, for where they have separated from the arches above them, decorated plaster, which at one time formed part of the general ornamentation of the building, is exposed to view. At this stage in the history of the chapel the third coat of plaster was spread over the walls, thus giving three coats on the oldest parts where unaltered—two coats on the first alterations, and one coat on the second alterations. The fourth coat of plaster is still later, marking some less serious repair of the chapel.
The voussoirs of the lateral dome arches should be
noticed. They do not radiate to the centre, but are laid flatter
and radiate to a point above the centre. This form of construction,
occurring frequently in Byzantine arches, is regarded by some
authorities as a method of forming an arch without centering. But
in the case of the lateral wall arches before us it occurs where
centering could never have been required; while the apse arch,
where centering would have had structural value, is formed with
true radiating voussoirs. The failure of the
voussoirs to radiate to the centre therefore seems to be
simply the result of using untapered voussoirs in which the
arch form must be obtained by wedge-shaped joints. For if these
joints are carelessly formed, the crown may very well be reached
before the requisite amount of radiation has been obtained. On the
other hand, if full centering had been used, we should expect to
find marks of the centering boards on the mortar in the
enormously thick joints. But neither here nor in any instance where
the jointing was visible have such marks been found. Still, when we
consider the large amount of mortar employed in Byzantine work, it
seems impossible that greater distortions than we actually meet
with in Byzantine edifices would not have occurred, even during the
building, had no support whatever been given. It seems, therefore,
safe to assume the use of at any rate light scaffolding and
centering to all Byzantine arches.
