Well, there are many medieval customs and uses that are totally obsolete today. I will give you a few examples, three so as not to bore you, which will amaze you.
The wedding night was public
Medieval weddings hardly resemble today’s. The normal age of the spouses was just leaving childhood and beginning adolescence, between 12 and 15 years. Marriages were not celebrated for love, but for common interests such as the union of lands or obtaining greater social protection. And on wedding nights, pay attention, family and friends took the bride and groom to bed (to put them to bed, they said then) and stayed in the bedroom until the consummation of the marriage. Let us remember that only when it has been consummated is there a true marriage, so if the groom was not able to do so in front of those present, he was considered impotent and the marriage could be dissolved.
barely drank water
The lack of hygiene, the poor sanitation conditions and the continuous diseases made the water from wells and rivers not only undrinkable, but also a vector of infections. Hence, they depended on alcoholic beverages (wine, beer, mead…), which became drinkable after the fermentation process. Even the children drank these alcoholic beverages, although of a very low degree, since dysentery or a simple infection meant death if it was not cured soon.
The Inquisition did not burn witches
We have all seen a movie in which we are told how the Inquisition burned women with the fallacy of having practiced witchcraft. Well, it wasn’t like that at all. The Inquisition was a religious institution instituted to persecute heresy and only relapsed heretics (those who relapsed into the error they had abjured) were handed over to civil justice for execution. It would already be in the Modern Age when the Inquisition persecuted witchcraft, burning 59 in Spain, 4 in Portugal and 36 in Italy (Catholicism was more interested in the conversion and salvation of souls, in the return to the fold, and not so much in punishment). Nothing to do with the 100,000 women murdered by the Lutherans accusing them of witchcraft or the almost 50,000 who were murdered by the Calvinists, especially during the 30 Years War. But that is another story.
