The name Artus Manor comes from the Latinised form of the name of King Arthur. The legend of Arthur and the knights of the Round Table, popular at the end of the Middle Ages, has become an incentive for the cultivation of knightly traditions, not only by the nobles, but also by the rich Gdansk bourgeoisie who attempted to make themselves similar to the gentry. Another gathering of a similar character was also the Brotherhood of Saint George, whose patron, as is known, was a dragon slayer according to legend. But going back to the Artus Manor. This building can be visited in Gdańsk at the Long Market, next to Neptune’s Fountain. It is a monumental building with a Gothic-Renaissance symmetrical facade. Its symmetry, however, is disturbed by two small elements, in the wall to the right of the entrance portal. They are a stone head with a demoniac expression, and an iron spike with barbs hanging on a chain. There is a legend associated with these objects. It speaks of a devil who had once come down from hell to Gdańsk to take part in the ball held one night at the Artus Manor. Eventually, after attempting to seduce a beautiful Gdańsk lady, the demon was beaten by the townspeople and driven out of the city. To commemorate this event, his tooth which had been knocked out during the fight was placed on the facade of the manor, next to the effigy portraying the unfortunate devil. In fact, the iron spike is the end of a knight’s copy that was used during encounters at knights’ tournaments. Placing this element on the facade of the Manor was most probably a symbol referring to the knightly traditions of this place. However, with time, as the knights’ traditions withered away, the memory of the real function of the artefact was also blurred, hence an impressive legend was concocted. However, the problem of the origin of the mysterious stone head remains an unsolved mystery.
