The church was rebuilt by Isaac Comnenus, Alexius's third son. However, it was only after the third phase of building, two centuries after, that the church as it stands today was completed. The powerful Byzantine statesman Theodore Metochites endowed the church with many of its fine mosaics and frescos. Theodore's impressive decoration of the interior was carried out between 1315 and 1321. The mosaic-work is the finest example of the Palaeologian Renaissance. The artists remain unknown. In 1328, Theodore was sent into exile by the usurper Andronicus III Palaeologus. However, he was allowed to return to the city two years later, and lived out the last two years of his life as a monk in his Chora Church.
