Kitzinger compares a roundel of Hadrian lion-hunting, which is "still rooted firmly in the tradition of late Hellenistic art", and there is "an illusion of open, airy space in which figures move freely and with relaxed self-assurance" with the later frieze where the figures are "pressed, trapped, as it were, between two imaginary planes and so tightly packed within the frame as to lack all freedom of movement in any direction", with "gestures that are "jerky, overemphatic and uncoordinated with the rest of the body".
