In this view, there are many interesting details of a chariot race that may not be available anywhere else.
We know that in general there were four major "teams" that were in play in the Roman world: the reds, whites, blues, and the greens. In the lower-left, note that charioteers are clad in red and white. The two charioteers above the spina are clad in blue and green!
There are two rectangular pools that form the basis of the spina. They were filled with water which seems to be a unique style. Note also, the pyramid in the left portion of the spina.
In the lower right, there is a figure with two jugs—evidently, he wet down the track and may have cooled down the axles of the chariots. In the upper left, the standing person may have a whip to urge the teams on—or it may be some type of cutting instrument that could be used to free horses and charioteers from chariots that had crashed.
This large second century Roman Mosaic that was discovered in Lugdunum (modern Lyon) in 1806. On it, the details of a chariot race in the circus, or hippodrome, of Lugdunum is depicted. It is 16 feet long and 9 feet wide.
It is surrounded by a floral design, inside of which is a guilloche pattern, and inside of that the arena of the circus where 9 chariots are racing. No seating of the circus is represented and indeed the circus of Lugdunum originally had wooden seats that were destroyed by fire.
