A Fabulous Horse Bread by Gervase Markham, 1607

The big author for horse breads was Gervase Markham (ca 1568-1637 ). Markham is the horse trainer who perfected the type of breads fed to race horses as part of a structured exercise program for race horses, thus establishing horse training on a modern basis. The custom at the time was for men to agree amongst themselves to a cross country race three months in advance and then to begin a training regime.
