In the 1300s and 1400s the London population suffered from tuberculosis, typhus, influenza, leprosy, dysentery, smallpox, diphtheria, measles, heart disease, fevers, coughs, cramps, catarrhs and cataracts, scabs, boils, tumors, and "burning agues". There were also many deaths by fires, burning by candles near straw beds when drunk, falling downstairs when drunk, and drowning in the river or wells. Children were often crushed by carts, trampled by horses, or mauled by pigs.
Towns recognized surgery as a livelihood subject to admission and oath to serve the social good. Master surgeons were admitted to practice in 1369 in London in full husting before the mayor and the aldermen and swore to: [1] faithfully serve the people in undertaking their cures, [2] take reasonably from them, [3] faithfully follow their calling, [4] present to the said mayor and aldermen the defaults of others undertaking, so often as should be necessary, [5] to be ready, at all times when they should be warned, to attend the maimed or wounded and others, [6] to give truthful information to the officers of the city as to such maimed, wounded, or others whether they be in peril of death or not, and [7] to faithfully do all other things touching their calling.
Some young girls of good families were boarded at nunneries to be taught there. Some upper class widows retired there. Only women were allowed to be present at a birth, at which they spread the knowledge of midwifery. As usual, many women died giving birth. Various ways to prevent pregnancy were tried. It was believed that a baby grew from a seed of the father planted in the woman's body.
Infant mortality was especially high in boroughs and burgess family lines usually died out. A three-generation family span was exceptional in the towns, despite family wealth.
After the plague, gentlemen no longer had their children learn to speak Norman. The grammar schools taught in English instead of Norman as of 1362. Bishops began to preach in English. English became the official language of Parliament, in 1363, and in the courts, replacing Norman and Latin.
The requirements of elementary and higher studies were adjusted in 1393 and began the public school system. William of Wykeham's school, St. Mary College of Winchester in Oxford was the prototype. The curriculum was civil law, canon law, medicine, with astronomical instruments that students made, theology, and the arts. The arts textbooks were still grammar, logic, Donatus, and Aristotle. Many laymen were literate, for instance country gentry, merchants, and craftsmen. Laymen instead of clerics were now appointed to the great offices of state.
A will in 1389 in which a wealthy citizen arranges for one son to become an attorney and the other a merchant:
"Will of William de Tonge, citizen of London: One hundred marks each to my two sons. And I will that my said two sons shall live upon the profits of the money bequeathed to them above until the age of twenty years. And if my said two sons be well learned in grammar and adorned with good manners, which shall be known at the end of twenty years, and the elder son wish to practice common law, and if it is known that he would spend his time well in that faculty, I will that over and above the profit of the said one hundred marks he shall have yearly from my rents for the term of seven years five marks. And if he should waste his time aforesaid, or if he should marry foolishly and unsuitably, I will that he receive nothing more of the said five marks.
And if younger son wishes to attend the University of Oxford or to establish himself well in the mystery of a merchant after the age of twenty years, and [if] there be knowledge of his praiseworthy progress in his faculty or his carefulness in trading … I will that he shall receive five marks yearly in the manner described above for his maintenance, over and above the profit of the said one hundred marks to him bequeathed, for the space of seven years; and if he behave himself otherwise, I will that thereupon he be excluded from the said five marks. And in case the said bequest of 200 marks to him and his brother shall be annulled so that he shall have nothing therefrom … then the said 200 marks shall be spent upon all the yearly chaplains who can be had to celebrate divine service in the church of All Hallows for my soul."
Most great lords were literate. Many stories described good men, who set an example to be followed, and bad men, whose habits were to be avoided. Stories were written about pilgrimage vacations of ordinary people to religious sites in England. Will Langland's poem "The Vision of William Concerning Piers Plowman" portrays a pilgrimage of common people to the shrine of Truth led by a virtuous laborer. Mystics wrote practical advice with transcendental teaching, for instance "Scale of Perfection" attributed to Walter Hilton and "Cloud of Unknowing". Richard Rolle wrote about spiritual matters, probably the "Prick of Conscience". Richard de Bury wrote "Philobiblon" about book lovers. Jean Froissart wrote the "Chronicles" on knights. Courtly ideals were expressed in "Sir Gawaine and the Grene Knyght", wherein the adventures of the hero, an Arthur knight, are allegorical in the struggle against the world, the flesh, and the devil (1370). "Pearl" eulogized all that is pure and innocent on the event of the death of a two year old child. Marco Polo's book of discoveries on his journey to China was known.
