"Chariot racing book suggestions" Topic

What do folks suggest for books on chariot racing in the ancient world, especially during the Roman empire era?

Looked at Roman Circuses by John Humphrey and wondering what others here think would be essential reading for this subject.

Thanks,

Ben Hur

"And now, to make the turn, Messala began to draw in his left-hand steeds, an act which necessarily slackened their speed. His spirit was high; more than one altar was richer of his vows; the Roman genius was still president. On the three pillars only six hundred feet away were fame, increase of fortune, promotions, and a triumph ineffably sweetened by hate, all in store for him! That moment Malluch, in the gallery, saw Ben-Hur lean forward over his Arabs, and give them the reins. Out flew the many-folded lash in his hand; over the backs of the startled steeds it writhed and hissed, and hissed and writhed again and again; and though it fell not, there were both sting and menace in its quick report; and as the man passed thus from quiet to resistless action, his face suffused, his eyes gleaming, along the reins he seemed to flash his will; and instantly not one, but the four as one, answered with a leap that landed them alongside the Roman's car."

Seems like it's usually covered in books about gladiators, as a sub-topic…
