In addition to the church mosaics, a side mortuary chapel (the Parakklesion) has some unbelievable frescoes. It was dedicated to Theodore Metochites, who refurbished the Chora Monastery / Church in the 11th century and put in all the murals. The guy has a pretty fascinating history. He started off life in exile because his parents had tried to reunite the Eastern Orthodox and Roman Catholic faiths. He worked his way back into favor by arranging marriages for the Emperor and his cronies. Over time, he became treasurer, and later prime minister. But when a fight broke out between rivals for the throne, Metochites backed the wrong guy and was exiled once again. Eventually, he was allowed to return and became a monk in his own monastery.
