The doctor examined and treated Magda Logomer on the queen's request following the tortures she was submitted to, and by the correspondence between the high officials of the Kingdom of Croatia and the Court of Vienna.

63 witches were prosecuted under the witchcraft laws between 1740 and 1752, in the counties of Zagreb, Varaždin and Križevci, at the time when persecution was at its peak in the region.

The rules also require strict record keeping detailing the instruments and methods of torture used, and the precise dates and times.

[2] Examples of instruments used for torture included wheel and dismemberment,and the tourniquet, which consisted of tightening the neck with a screw and gradually increasing the pressure.

[2] Being herbalist meant in practice collecting grasses and making remedies, but it is not known how she was trained for this profession, which required a good knowledge of plants.

Matija Sunsić, a witness at the trial, stated that Magda confessed to him that only fear of Švagel prevented her from using her healing skills.

She could therefore have used this fear for her own interest, but also sought to resolve disputes by paying compensation in order to avoid being accused of witchcraft, elements that were found in several of her physical altercations.

[2][4][5]Magda Logomer was sent to a medical clinic, and Gerard van Swieten, the personal physician of Maria Theresa of Austria, examined her.

On June 9, 1758, Maria Theresa was informed of the case and ordered Count Franjo Nadaždi, then ban of the kingdom, to send Magda to her so that she could meet her in person.

Magda was examined by De Haen, a professor of medicine, and Gerard Van Swieten,[6] who was also the court expert on witchcraft in addition to being the personal physician of the empress.

[8] On November 23, 1758, the Empress in a letter addressed to the ban of Croatia acquitted Magda[5] and sent her back home to Križevci under special protection.

However, the records show that her husband died two years after her return, as did two of the people who had accused her, which must not have made her social reintegration any easier, given the local rumors and suspicions of witchcraft against her.

It could conduct trials without interference, pronounce death sentences without having to refer to a higher court of the Austro-Hungarian or Croatian monarchy.

[9] Marie Thérèse wanted to eradicate superstition in her kingdom, and hunting witches and black magic was no longer her priority.

In 1740, the same year that Frederick the Great prohibited the use of torture in witch trials, Maria Theresa issued a decree specifying that all witchcraft cases were to be dealt with solely under imperial jurisdiction.

In 1766 this decree was reinforced by a General Ordinance on the attitude to be adopted, which stated:[10]During our reign no authentic sorcerer has ever been discovered, but trials of this kind have always been based on deception due to the wickedness, stupidity or insanity of the accused or on some other vice.

[11] Marija Jurić Zagorka published Grička Vještica (The Witch of Grič ) based on real historical facts.

The report of Dr. Gerard van Swieten was published in 1913 and 1924 in the newspaper Obzor, and the case is discussed in the correspondence between the high officials of the Kingdom of Croatia and the Court of Vienna, these documents constituting historical records.
