Palio di Legnano in the context of Legnano

Horse racing is an equestrian performance activity, typically involving two or more horses ridden by jockeys (or sometimes driven without riders) over a set distance for competition. It is one of the most ancient of all sports, as its basic premise – to identify which of two or more horses is the fastest over a set course or distance – has been mostly unchanged since at least classical antiquity.

Horse races vary widely in format, and many countries have developed their own particular traditions around the sport. Variations include restricting races to particular breeds, running over obstacles, running over different distances, running on different track surfaces, and running in different gaits. In some races, horses are assigned different weights to carry to reflect differences in ability, a process known as handicapping.

A medieval pageant is a form of procession traditionally associated with both secular and religious rituals, often with a narrative structure. Pageantry was an important aspect of medieval European seasonal festivals, in particular around the celebration of Corpus Christi, which began after the thirteenth century. This festival reenacted the entire history of the world, in processional performance, from the Bible's Genesis to the Apocalypse, employing hundreds of performers and mobile scenic elements. Plays were performed on mobile stages, called waggons, that traveled through towns so plays could be watched consecutively. Each waggon was sponsored by a guild who wrote, designed, and acted in the plays.
