Abstract
Based on an analysis of the typographic material of Rhegius' Catechism (Prague, after 6 June 1547), this paper breaks the earlier myth of the beginnings of the Czech printer Jiří Melantrich. An analysis of the printed letters and the title border leads to the conclu-sion that Melantrich cooperated with the Catholic printer Bartoloměj Netolický - not after Ferdinand's ban on printing press (in the autumn of 1547), but already in the summer before the publication of Rhegius' Catechism.
This is clearly proved by an analysis of the typo-graphic means of the Catechism, which belonged to Netolický, to whom they later returned.
