Santa Maria Maggiore, Rome: details of the Cosmatesque floor

NOTES: This drawing appears to have served as the basis for plate 6 in Wyatt's Specimens of the geometrical mosaic of the middle ages (London, 1848). The book was based on papers Wyatt had read at the Royal Institute of British Architects, the Royal Academy of Arts and the Archaeological Institute of Great Britain and Ireland, so this drawing perhaps was one that was used on those occasions.
