This article analyses translations of Ep. 5,27 by Marsilius Ficinus (Veritas de institutione principis): the work of an anonymous translator (perhaps Ř. Hrubý) and a later translation by O. Velenský. The article also analyses translations of Historia Bohemica by Aeneas Silvius (Konáč, 1510; Adam, 1585). The first Ficinus translation simplifies the ancient realia, avoids Latin infinitive constructions and translates some words with two expressions (multiplication). Velenský imitates Latin grammar in Czech. Konáč adheres to the verbum e verbo method, but substitutes words considered critical by Utraquist readers. Adam translates faithfully, but like the first translator of Ficinus, he uses multiplication and explicates within the translation. The translation style for the more literarily challenging texts was influenced by the translators’/publishers’ estimation of the readers’ skills.
