Casimir the Great, the last king of Poland from the Piast dynasty, did not leave any heir but the important legacy was the Wisliczko-Piotrek statutes, the first kind of legal code. There are mentioned there rights for beekeepers, who were engaged in a special kind of beekeeping that consisted in collecting honey from beehives, i.e. specially hollowed out hollows of trees, mainly oaks and pines. In those times, this was a particularly respected profession, inherited and honoured with the privilege of delivering honey to the court of a duke. At that time, honeys from barns, heather or lime honeys were considered to be of high quality, both in terms of taste and nutritional value. This profession required a certain amount of dexterity and strength, since climbing up the tree to the beehives was done with the help of ropes, which not everyone was able to do.
With time, the profession of beekeeper disappeared in favour of beekeeping and keeping bees in beehives, but recently there have been attempts to restore the profession, albeit to a limited extent due to forest protection. In the old days, in Poland (and neighbouring areas) there were many forests. And beekeeping was known and practiced long before Casimir the Great and his statutes. As far back as in the times of the Piast legends, the legendary Piast Chościskowic, the progenitor of the family, was sometimes ascribed the profession of beekeeper or wheelwright (M. Bielski, a historian from the 16th century). Old beekeeping, though not only in Poland, has been an element of the "Polish style" since the oldest legends.
