Shire knights performed a number of duties. They served a sheriffs, escheators, coroners, and justices on special royal commissions of gaol-delivery. They sat in judgment in the shire court at its monthly meetings, attended the two great annual assemblies when the lord, knights and freeholders of the shire gathered to meet the justices on eyre, 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 shire court to Westminster when summoned there by the kings' judges. They served on the grand assize. As elected representatives of their fellow knights of the shire, they assessed any taxes due from each hundred. They investigated and reported on local abuses and grievances. The king's judges 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 at the royal eyre. Everyone was taught to read and write in English. Even obscure villages gathered children together for this schooling. 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, logic [dialectic], and rhetoric [art of public speaking 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. There was no examination for admission as an undergraduate to Oxford, but a knowledge of Latin with some skill in speaking Latin was a necessary background. The students came from all backgrounds. Some had their expenses paid by their parents, while others had the patronage of a churchman, a religious house, or a wealthy layman.
