Note 2218 — Chapter VII · THE MATERIALS OF OLYMPIC VICTOR MONUMENTS, AND THE OLDEST DATED VICTOR STATUE.2172
Reading edition
Deonna, op. cit., p. 85, says that the size of the αἰδοῖα is an indication of archaism, as the earlier artists exaggerated them in order to show the sex better. Figs. 7 (example from the Kerameikos) and 72 (example from Delphi), on pp. 132 and 179 respectively of his work, resemble our statue in this feature.
