 It has been proposed that there were statues positioned on top of the lower level, on either side of the central, "aediculum"-like, niche of the upper level, as was common for this architectural form; Theseus and Hadrian are the most commonly advanced candidates for these two statues, based on the inscriptions.Ward-Perkins has proposed that the attic held additional multiple statues, located over the projecting Corinthian columns of the lower level.In stark opposition to these proposals, Willers states that there is no evidence of the type of doweling needed to mount statuary on the top of the lower level and that the stone is far too roughly worked on the upper surface for statues to rest on it.
