The first direct evidence that games probably resembling football were being played at English public schools comes from the "Vulgaria" by William Horman in 1519. Horman had been headmaster at Eton (1485/6–1494/5) and Winchester College. His Latin textbook includes a translation exercise with the phrase "We wyll playe with a ball full of wynde", a rough translation of the original Latin "Lusui erit follis pugillari spiritu tumens", which Francis Peabody Magoun translated as "In sport we shall have a ball inflated with air to kick". Even as early as 1519, Horman shows us that he was well aware of the value of sports to children's education and the need to temper their enthusiasm in order not to affect their studies: "There muste be a measure in gyuynge of remedies or sportynge to chyldren, leste they be wery of goynge to theyr boke if they haue none, or waxe slacke if they haue to many".
