Origins
of Harness Racing.
In 1500
BC the Assyrian kings kept elaborate stables with professional
trainers. They trained horses to pull chariots, initially for use in
battles but soon they were also used for hunting as a sport. Local
horses were bred with horses brought in from Asia Minor and Northern
Africa. In the 7th century BC, the Olympic Games had four-horse hitch
chariot races; two-horse hitch races took place earlier.
Chariot
racing as a sport gained great prominence in Rome. Public records of
the bloodlines of horses were kept. The top horses even had their
records buried with them. One horse had 1300 victories, 88 second and
37 third placements.

The Circus
Maximus hippodrome was built on a site for chariot racing in the Murcia
Valley between the Palatine and the Aventine hills. It was 600 metres
long and 200 metres wide. Except at the open end, seats ran in tiers
around the U-shaped arena. They consisted of two parallel terraces
facing each other along the long sides of the track connected by a sharp
curve curve in the terrace facing the stables at the other end. By the
4th century AD it could hold 200,000 spectators. A fence ran down the
middle, called a spina, to make laps. This was most
probably done to eliminate the possibility of head-on collisions and
prevented horses being distracted by seeing another team coming towards
them at close range.
In Greece
chariot racing had been the sport of the wealthy. In Rome companies
distinguished by their colours of white, red, blue and green took part.
During the reign of Agustus, 27BC-A.D.14, there were 12 races a day and
each race consisted of seven or twelve laps. By the time of Flavius'
reign, A.D.69-96, there were 100 races from dawn to dusk. As in today's
sport, they had proper racing officials, starting chutes, legal
disputes, claims of doping horses and betting.

Circus Maximus, Rome. One of the
largest sports venues ever built.
Rebuilt in the first century B.C. Modified until 400 B.C. Only ruins remain.

Eventually
the chariot passed its use by date as a military vehicle and chariot
racing ended with the fall of Rome in the 4th century.
