The last mosaic has the inscription:
VOTIS XXX MVLTIS โง XX BIS XX CVRANTE YACINTHO COMITE FABRICA AD SVMMVM PER DVCTA ES CVLMEN
Translation
For vows on the thirtieth anniversary of the rule of the emperor, and more (vows) for (another) twenty years, and twenty more years again. Under the care of Hyacinthos holding an office, building, to the highest summit, you were drawn.
Notes
Edit: I thought it was Constantine I, but it is more likely the emperor is Constantius II based on numismatic evidence. For comite, see L&S s.v. comes II.E.
