panel is a stylisted version of the race course in the circus, which four quadrigae, each drawn by four horses which run around the spina (the median strip) which has an obelisk in the centre, covered with stylised simplifications of Egyptian hieroglyphs. This might recall the Circus Maximus and its obelisks. At the two ends of the spina are things which seem to represent groups of statuary. The depiction of the race track is very interesting both for its subject matter and for its technical execution, which stylises the course and all its features within the restricted space of the panel in a very efficient way, using side, front, and back views of the space alternately.
