Detail of the panel depicting Aion from the Monument of C. Iulius Zoilos.
Particular attention has been paid to modelling the feet of this figure, with his left foot slightly overlapping the edge of the frieze, a deliberate detail intended to give the subject a lifelike quality. Peter Rockwell notes that, when at art school, he was taught that when carving relief figures to go high on a monument it was good idea to carve their foot projecting slightly to provide the viewer with a reference point that would allow them to appreciate the full height of the figure.
