Page "Apollo" Paragraph 307

Another haloed Apollo in mosaic, from Hadrumentum, is in the museum at Sousse.

The conventions of this representation, head tilted, lips slightly parted, large-eyed, curling hair cut in locks grazing the neck, were developed in the 3rd century BCE to depict Alexander the Great.

Some time after this mosaic was executed, the earliest depictions of Christ would also be beardless and haloed.
