Places connected to places by virtue of the use of the same stamped brick type, overlaid against latitude and longitude
4th – 6th century stamped bricks connected by virtue of use in the same location, around Constantinople
Places connected to places, by virtue of use of the same stamped 4th to 6th century bricks, around Constantinople
