The figure between the first and second window is probably Jonas, as ΑϹ still remains on the right side of the head, and there is only room for three letters on the other side. The undergarment is a greenish blue with silver lights, and has broad red stripes. The nimbus is blue.
Over the head of this figure is found the remnant of an inscription ΝΤΙΔΟϹ. This may have belonged to one of the figures above, of which a sandaled foot and edge of a garment alone remain. The foot does not stand upon green earth, like the prophets below, and therefore probably belonged to an angel. Only a part remains of the third prophet from the east, which was inscribed Habakkuk.[389]
The mosaics on the soffite of the eastern arch were covered before drawings were made. At the crown is a medallion with a white ground. In this is a low throne of gold, with two green cushions upon it; over them is thrown a blue cloth with a white hem, and upon that is placed a golden book. Above is also a gold cross with three arms; the middle one is the longest, and at its intersection with the upright member is a circle. On the south face of this eastern arch is the figure of John the Baptist, with long hair, and a brown shaggy garment; his right hand blesses, and his left holds a cross with three arms. Opposite, on the north side is the Virgin, with uplifted hands in the attitude of prayer. She has a white undergarment, bound with a golden girdle, a red upper garment, and a veil of a green-blue, with a gold hem. Under her is John Palaeologus, who restored this part, and to whose time these figures and designs certainly belong. The emperor wears a crown, with strings of pearls on either side. He has a closely fitting undergarment of gold, decorated with pearls and embroidery. A magnificent cloak hangs down from the left shoulder, and round the neck and breast is a kind of broad gorget richly embroidered. In his right hand is a sceptre, and in his left a roll.
The archangel on the south side of the bema vault[390] has a globe in the left hand, and a staff in the right. He is clad in white, with imperial red shoes. The arch of the apse bears an inscription, which ends with the letters ϹΕΙΕ ΠΑΛΙΝ.
On the conch of the apse is the Mother of God upon a throne, holding the Child between her knees; her upper garment, which is blue, conceals the whole figure, except that at the breast, under the arm, and above the feet, the white and gold garment beneath is visible. The Child has his right hand uplifted and his left against his breast. He wears a white garment, with a gold girdle. His hair falls down freely, and the nimbus has three streams of light. The throne is gold with red ornaments, but is without a back, and the footstool is of green silk.
In the dome pendentives are Cherubim with six wings. Each head is four feet two inches high. The upper feathers of the wings are a light green, and the under feathers brown.[391] The great centre-piece of the dome, which, according to Du Cange, represented Christ as Judge of the World seated upon a rainbow, no longer exists.
Only one of the domes of the gynaeceum preserves its mosaic ornament of figures. This[392] represents the descent of the Holy Spirit. Only a part remains of the throne in the centre; on it is a green cushion, and a blue cloth with gold patterns. Groups of spectators fill the pendentives of the vault.
Above the doorway which leads from the western gynaeceum to the chambers over the south porch, are remains of figures, which can no longer be identified.[393] In the ceiling of the chamber over the stairway is a design of green tendrils on a gold ground.[394]
The small dome in the chamber which opens out of the western buttress of the south side on the first-floor level has four angels with uplifted hands, supporting a medallion in the centre. This design is similar to that in the side chapel at S. Prassede at Rome.
“The figure representations belong to the time of Justinian, though the Silentiary, otherwise so accurate, does not describe them.”
