County knights served sheriffs, coroners, escheators, and justices on special royal commissions of gaol-delivery. They sat in judgment in the county court at its monthly meetings, attended the two great annual assemblies when the lord, knights and freeholders of the county gathered to meet the itinerant justices who came escorted by the sheriff and weapon bearers. They served on the committees which reviewed the presentments of the hundreds and village, and carried the record of the county court to Westminster when summoned there by the kings' justices. They served on the grand assize. As elected representatives of their fellow knights of the county, they assessed any taxes due from each hundred. Election might be by nomination by the sheriff from a fixed list, by choice, or in rotation. They investigated and reported on local abuses and grievances. The King's justices and council often called on them to answer questions put to them on oath. In the villages, humbler freeholders and sokemen were elected to assess the village taxes. Six villeins answered for the village's offenses before the royal itinerant justice. Reading and writing in the English language was taught. The use of English ceased to be a mark of vulgarity. In 1258 the first governmental document was issued in English as well as in Latin and French, and later Latin started falling into disuse. Boys of noblemen were taught reading, writing, Latin, a musical instrument, athletics, riding, and gentlemanly conduct. Girls were taught reading, writing, music, dancing, and perhaps household nursing and first aid, spinning, embroidery, and gardening. Girls of high social position were also taught riding and hawking. Grammar schools taught, in Latin, grammar, dialectic (ascertaining word meaning by looking at its origin, its sound (e.g. soft or harsh), its power (e.g. robust and strong sound), its inflection, and its order; and avoiding obscurity and ambiguity in statements), and rhetoric [art of public speaking, oratory, and debate]. The teacher possessed the only complete copy of the Latin text, and most of the school work was done orally. Though books were few and precious, the students read several Latin works. Girls and boys of high social position usually had private teachers for grammar school, while boys of lower classes were sponsored at grammar schools such as those at Oxford. Discipline was maintained by the birch or rod.
