Detail of Sebasteion panel depicting Bellerophon.
Bellerophon's feet, as can be seen in this detail, are carved down into the base of the panel. This suggests that the figure was not accurately planned out before carving began and the carver ran out of space for the feet when he reached this area of the panel. This is a detail seen on a number of the Sebasteion panels and indicates that the carvers responsible were not working from carefully measured drawings or models.
