Click the picture for a bigger image so you can see the globe more clearly and you will observe that it has latitude lines with the poles implied drawn upon it. There is a second set of latitude-like lines but these would not match the poles. Modern globes have longitude lines converging on the North and South poles, but the mosaic doesn’t have them.
The lines drawn upon the original globe I have extended into complete circles so their center points could be found and I drew small circles about the point for easy visibility. That turns out to be significant because the center of the smallest circle on the globe is identical to the center of a much larger circle drawn in light gray color following the line of the circumference of the bench the sages are sitting on.
In an effort to find a significance for these circles I repeated them using formerly defined hot spots for centers. There were some random coincidences, but I didn’t find any that satisfied my criterion of multiple significant intersections as found for the lines discussed in former posts.
Another unusual feature that must be commented upon is the leg of the sage under the sundial; that leg is shaped remotely like the Italian peninsula and set at the same angle relative to north. I made an effort to overlay modern maps upon the mosaic but was unsuccessful in finding a comfortable conformity.
The mosaic seems to define the periphery of the Roman Empire between the founding of “York” 71 AD and the eruption of Vesuvius in 79 AD.
