Санта-Мария-ин-Домника
With the political stability brought about by the Frankish conquest of Italy there was a new burst of production of major Roman mosaics in the Carolingian period. The great hall (triclinium) of the Lateran Palace had religious mosaics in its apse-like semi-dome which survive, now moved outside and very heavily restored. Five churches in Rome have mosaics from this period:Santi Nereo e Achilleo (c. 814) has an iconographically eccentric programme at the east end, while Santa Prassede and Santa Cecilia in Trastevere (both c.820) and San Marco (commissioned between 828 and 848) all have semi-domes following that of Santi Cosma e Damiano (526-30 - above) with Saints Peter and Paul presenting martyrs and the donor Pope carrying a model of the church. Santa Maria in Domnica (c. 820) has an enthroned Madonna and Child in the midst of saints and angels.
