[1] Historian David Blackbourn has pointed out that a number of features in Lateau's life are similar to that of other mystics such as Anna Katharina Emmerick and to the experiences of visionaries such as Bernadette Soubirous and Catherine Labouré.
[3] Beginning 24 April 1868, pain recurred every Friday and blood began to flow from her left side and feet.
On 25 September, the stigmata was completed by the appearance on the breast of four small spots of blood as if coming from four pinpricks to the heart.
[6] Lateau's claims of stigmata were disputed by Donovan Rawcliffe, who suggested they were self-inflicted, caused by "extreme emotional or other psychogenic factors following intense concentration on the crucifixion.
"[7] On 17 July 1868, the phenomenon of the bleeding of the stigmata was accompanied by an ecstasy, which returned every Friday in the form of a trance-like state that lasted for a total of 8 hours.
[9] She was insensitive to pain and noises, but could briefly exit the ecstasy following a request of the parish priest of Bois-d'Haine or some clergymen.
The commission was made up of clerics; a layperson, who was Minister of State Adolphe Dechamps; and a physician, Dr. Lefebvre of the Catholic University of Louvain.
The investigation acknowledged Lateau's sincerity and the authenticity of the facts and concluded that science could find no rational explanation as to what had happened to her.
Physician Évariste Warlomont suggested attributing the phenomena to "double consciousness" (later termed dissociative identity disorder).
According to skeptic Bergen Evans, "Dr Warlomont, an uncouth and discourteous fellow who was sent to investigate her claims by the Belgian Royal Academy of Medicine, unexpectedly wrenching upon a cupboard in her room, found a cache of food, and got Miss Lateau to admit that, while she never slept, she was subject to nocturnal periods of forgetfulness.
