In 15 century at the universities of Europe was studied epistolografiyu - science to write letters. To help to instructors and to students were comprised special textbooks - the collections of the samples of letters in the different cases of life.
At the Krakow university thus they taught to compose right(!) the love letters: beginning with the refined greeting, then it was necessary to praise the beauty of addressee with the required addition about the attractiveness and virtues, to further add wish so that the recipient of letter would be exponential, satisfactory and healthy, and complete letter about fate to the will of Most High, about his patronage and protection. However, then university reform abolished this obligation and, that the most interesting, this opened road for the variety and originality in the expression of feelings. Yes is in good health freedom!
In the later publications, for example, in the "manual" 1822 it is said: "love letters are invented for the report of the thoughts of their to others. They serve instead of the verbal conversation, and as before the eyes represent people, removed from each other, even in the great distance." Very precise statement. But are such their recommendations about the writing? "Written style must not be too high, not constrained not clownish. It must be simple and similar to the usual conversation, depicted on the paper. It is simpler, the more pleasant it is, the nearer to the heart. The rhetorical figures are not necessary for it: many exclamations, rotation, just as the long periods, necessary sometimes in other kind of compositions. However, in order to write simply and is free, must thoroughly know its language in order not to lose equilibrium and, after rising is too highly, not to undergo the incidence. The more we work above the letter, the more imperceptible must be, that we worked. Craftsmanship lies in the fact that to hide skill and to approach how much it is possible nearer to nature: so that everything would seem natural, those freely discharging; so that everyone could say that this otherwise better cannot be expressed".
