The Birth of Alexander the Great.Mosaic, 4th century BCE. From Baalbek,Lebanon. National Museum of Beirut.
In the case of this mosaic, the name-labels seem to serve an obvious and important purpose: how else can the viewer recognize the scene as the birth of Alexander rather than the birth of Achilles or Dionysos? At the same time, the borrowing of the iconographic schema hints at analogies between Alexander, Achilles and Dionysos.
