Trigarium

[2] It may be part of a larger field set aside as a public space for horse pasturage and military drill for youths, which was the original purpose of the Campus Martius.

The faction headquarters of the professional charioteers were established nearby, with the trigarium just northwest of the stables and clubhouse of the Green and Blue teams.

[5] An adjacent area where people played ball and hoop games and wrestled was the site of temporary wooden stadia built by Julius Caesar and Augustus and finally the permanent Stadium of Domitian.

[7] Pliny uses the word to mean equestrian exercise generally: he describes a fortified water or sports drink, prepared with powdered goat dung and vinegar, that was drunk by Nero "when he wanted to strengthen himself for the trigarium".

[15] Isidore of Seville comments on the sacral origin of chariot races as part of the public games (ludi), which were held in conjunction with certain religious festivals.

The races of the Equirria on February 27 and March 14, also celebrated for Mars, may have been held at the trigarium as well, and possibly events for the ludi tarentini, which became the Saecular Games.
