The article decribes a learned rivalvry between two high schools in Prague - the Utraquistic Charles-Academy and the Jesuit Ferdinand-Academy at St.Clemens. Although both schoools were divided by a different confession, there was a fruitful intellectual competition between them on the field of education of students, which finished definitively in 1622, when the Utraquistic Academy was abolished by order of the emperor and the Vienna-government and the Prague University turned back to catholic religion under custody of Jesuits.
