A princess would be raised to marry a prince or king,a nd as such she would have many responsibilities. She would be expected to be pious, and to go to Mass often and pray frequently. she would be given a good education (princesses and queens were expected to be cultured and take an interest in books and writers). She would be expected to interest herself in charities. When she married and had children she would be responsible for overseeing their upbringing and education. She migth have to act as regent while her husband was away, and therefore would be expected to take an intelligent interest in government.
In 'Treasure of the City of Ladies' a book of advice for women of all classes (but especially royal and noble women, who would be the ones most likely to purchase her book) Christine de Pisan suggested what a day in the life of the ideal princess would be like:
"She will rise early every day, and address her first words to God. When the lady is ready she will go to hear her Masses, as many as time and leisure will permit her....This lady will have such a good, orderly, system that when she leaves her chapel there will be some poor people at the door to whom she herself will give alms from her own hand, and if any deserving petitions are made to her, she will hear them kindly and give a gracious reply. She will not detain those that she can deal with quickly, and she will therefore increase her alms and also her great renown...
When she has done these things, if she has responsibility in government, she will go to the council chamber on days when it is held. There she will have such a bearing, such a manner and such an expression when she is seated in her high seat that she will indeed seem to be the lady and mistress over all, and everyone will hold her in great reverence as their wise mistress with great authority. She will conscientiously hear the proposals that are put forward and listen to everyone's opinion. she will be so attentive that she will grasp the principle points and conclusions of matters and will note carefully which of her counsellors speaks better and with the best deliberaton and advice, and which seem to her th e most prudent and intelligent...
After the morning council she will have her midday meal, which ordinarily and especially on solemn days and on feast days will be in the hall, where the ladies and maidens are seated, and other suitable persons ranked according to their position at court. ..After the tables have been taken up and grace has been said, if there are any princes or lord present, if there are any ladies or damsels or other visitors around her, then she will receive each of them in such honour as is fitting so that everyone will feel contented. She will speak to them ina thoughtful manner, with a pleasant expression, to the elderly people in a more serious manner, to the young people in a different and merrier one. and if one happens to say or hear any amusing thing or any merriment she will know how to contain it with such a pleasant manner that everyone will say she is a gracious lady and one who well knows her manners in all places.
After the spices have been taken up and it is time to retire, the lady will go to her chamber, where she will rest for a short while if she feels a need to. Then afterwards, if it is a weekday and she has no more importnat occupation with which to avoid idleness, she will take up some work, and she will have th ewomen and girlss around her work similarly. In the privacy of her chamber she will wish each of them to choose freely whatever she likes from all respectable kinds of merriment, and she herself will laugh with them and divert herself in private gatherings so unrestrainedly that they will all praise her great liberty and indulgence and they will love her with all their hearts. She will be occupied like this until the hour of vespers, when she will go to hear them in her chapel if it is a feast day and if no weighty business prevents her, otherwise she will say them without fail with her lady chaplain. After doing this, if it is summer she will go off to amuse herself in a garden until supper-time, walking up and down for her health. She will wish that if any persons need to see her for any reason they be allowed to enter and she will hear them. At bedtime she will pray to God. And that concludes the schedule of the ordinary day of the prudent princess living in good and holy occupation.
As for other amusements in which ladies are accusotmed to take their pleassure (like going hunting sometimes hunting with a falcon by the river for aquatic game and other pastimes), we do not add these things to the order of our discipline and teaching, for we leave them to the preference and desire of their husbands and themselves."
