Detail of the unfinished athlete modelled on the Polykleitan diskophoros from the Sculptor's Workshop.
Since it was common for carvers in the Roman period, especially at Aphrodisias, to define their subjects first in two dimensions and then three, working in from the front of the block, it is impossible to say for sure whether this was intended to be a relief or a free-standing statue. In this case a high relief seems most likely.
