Abstract
Crux of Telcz was an avid copyist who seems to have never simply copied the texts but rather always adjusted and appropriated them. This paper will concentrate on a case of his "creative copying" for which there survives a probable direct manuscript model: a sermon on the New Year by Johlín of Vodňany.
Crux has started to copy the sermon but then decided to make very substantial (and rather curious as far as their content is concerned) interventions. This case will serve as a basis for more general reflections on the nature of "editing" within late medieval manuscript culture.
