To prevent Incitatus, his favourite horse, from being disturbed he always picketed the neighborhood with troops on the day before the races, ordering them to enforce absolute silence. Incitatus owned a marble stable, an ivory stall, purple blankets, and a jeweled collar; also a house, a team of slaves, and furniture – to provide suitable entertainment for guests whom Gaius invited in its name. It is said that he even planned to award Incitatus a consulship.
