The young count had been a captain in the service of Austria, but had been cashiered for irregular conduct, and for disrespect to Prince Louis of Baden, commander-in-chief. To check him in his wild career, and bring him to sober reflection, his brother the prince caused him to be arrested and sent to the old castle of Van Wert, in the domains of Horn. This was the same castle in which, in former times, John Van Horn, Stadtholder of Gueldres, had imprisoned his father; a circumstance which has furnished Rembrandt with the subject of an admirable painting. The governor of the castle was one Van Wert, grandson of the famous John Van Wert, the hero of many a popular song and legend. It was the intention of the prince that his brother should be held in honorable durance, for his object was to sober and improve, not to punish and afflict him. Van Wert, however, was a stern, harsh man of violent passions. He treated the youth in a manner that prisoners and offenders were treated in the strong-holds of the robber counts of Germany in old times; confined him in a dungeon and inflicted on him such hardships and indignities that the irritable temperament of the young count was roused to continual fury, which ended in insanity. For six months was the unfortunate youth kept in this horrible state, without his brother the prince being informed of his melancholy condition or of the cruel treatment to which he was subjected. At length, one day, in a paroxysm of frenzy, the count knocked down two of his gaolers with a beetle, escaped from the castle of Van Wert, and eluded all pursuit; and after roving about in a state of distraction, made his way to Baussigny and appeared like a sceptre before his brother.
