I was recently shown photographs of this Piazza and the obelisk by friends who stayed nearby and asked about its present functioning as a sundial. (I understand it was originally set up nearby as a sundial gnomon in Roman times.)
The markings on the pavement seemed to me to be date related with perhaps a local time of transit taking account of EoT. I was told there is a slit in the globe which surmounts the obelisk so presumably a ray of light falls on the pavement with what I guess is a meridian line. I am sure some members of the list must have detailed knowledge of this; can anyone give more information please?
